Factory-Supported:

A factory-supported competitor in motorsports is a professional competitor who receives direct funding, top tier equipment, technical help, and logistics from a vehicle manufacturer or official team, allowing them to focus solely on competing at the highest level, unlike privateers who rely on personal funds or smaller sponsorships.

Matchless:

There is a publication well known in motorcycling circles written by Peter Hartley many years ago entitled ‘Matchless – Once the largest British motorcycle manufacturer’. That was when Associated Motor Cycles or A.M.C as it was usually referred, made AJS, Matchless, James, Sunbeam and Francis Barnett. AMC was not a manufacturer in its own right, but rather the controlling, parent company of the individual manufacturers. Their main factory was situated in Plumstead, South East London and with their AJS and Matchless brands, virtually dominated British trials in the early to mid-1950s, at a time when competition was rife.

Norman motorcycles were produced by Norman Cycles Ltd, who manufactured bicycles, autocycles, mopeds, and motorcycles from 1938 through to 1961 in Ashford, Kent. Founded by Charles and Fred Norman in a garden shed after World War I, the company evolved from making cycles to producing lightweight motorcycles and autocycles, this continued until 1961.

Triumph Engineering:

In 1898 Triumph decided to extend production at Coventry to include motorcycles, and by 1902 the company had produced its first motorcycle, a bicycle fitted with a Belgian Minerva engine. In 1903, after selling more than 500 motorcycles, Triumph began motorcycle production at the Nuremberg factory in Germany. During the first few years the company based its designs on those of other manufacturers, but in 1904 Triumph began building motorcycles based on its own designs, and 1905 saw the first entirely in-house designed motorcycle. The company went in for competition in all forms of the sport including racing, trials and scrambles as well as record braking.

We go back to a time when winners of motorcycle events would attend very formal end of season dinners and dances, the men dressed in dinner suits and bow ties with sharp white shirts and polished shoes, the ladies wore long dresses. A different time, immediate post war, we are about to revisit trials history.

Occasionally, the sport of trials witnesses family members and relatives taking up competitive riding, which usually results in much sibling rivalry, as trials is very much a sport for individuals and the competitors compete to win. This is the story of two extremely competitive brothers, both rode for British motorcycle manufacturers, Jack with Triumph and Sid with Associated Motorcycles and Norman, they were the Wicken Brothers.

The Wicken brother’s parents were Sidney Edward and Beatrice, who set goals for both Jack and Sid to achieve and this set the tone for many competitions in life between the two brothers, Sid always striving to match his older brother Jack, or better him, which in later life, including the desire to live longer than him and reach the golden age of 85 years.

S.R. Wicken:

Sidney Ronald Wicken, known as ‘Sid’ was born in Woolwich, South East London on 17th July 1929, just a stone’s throw from the AMC factory at Plumstead, and grew up there with his brother Jack. He was to ride trials on factory prepared machines, first the Norman and secondly Matchless, in national and International trials events. His brother would eventually ride for the Meriden Triumph factory in national trials and the ISDT.

During the second World War, Sid was evacuated to Teston/Malling near Maidstone in Kent, a place where he learnt to fish, he loved to tell stories of his time there to his children, unfortunately he contracted Cerebral Meningitis. When born, Sid had what is known as a ‘cleft palate’ which required specialist surgery and this resulted in a scar on his top lip.

After his school days, Sid started a five-year apprenticeship as a carpenter with Thomas Edge, builders and joiners in Woolwich, where he was well trained.

Sid could build furniture to the standard of a cabinet maker, and could also cut and pitch a roof.

During this time Sid’s attention was captured by motorcycle trials and his first event was in 1947 on an AJS with girder forks, winning the Best Novice award in the Beggar’s Roost national trial.

National Service was mandatory post war and Sid was enlisted from 1948-1950 in the British Army where he was head hunted to ride for the Royal Signals.

During his National Service, Sid married Edna Yvonne Ross in 1950 and started their family with Stephen born in April 1951; followed by Linda in July 1952; Christine in January 1957; Yvonne in December 1958 and finally David in August 1960. Initially living with Edna’s parents in Elibank Road in New Eltham, London.

In 1954 Sid and wife Edna moved into a multi-storey flat in Putney. He joined Chelsea and Kensington as a clerk of works, later moving into Building Control as a Building Surveyor when he joined the Orpington Council around 1955.

It is believed that Sid had been loaned an AJS from the factory from time to time, as well as outings on a factory Triumph, but he accepted Karl Pugh’s offer to ride for Norman in April 1954. Sid had also struck up a friendship with the doyen of trials commentating, Ralph G.V. Venables.

Sid managed to convince the local Norman factory to support him for the forthcoming 1954 Scottish Six Days Trial. The factory fielded an eight man and machine team effort that year and provided Sid with a used machine, registered SKK59, it required a comprehensive rebuild and he only received the machine the week before the Scottish. This resulted in taking the bike up without its wheels in the lift in Putney and making it ready and reliable for the 1954 Scottish in the kitchen. The factory supported Norman riders for 1954 were: Karl Pugh, Brian Butt, Gerry Mills, Clive Mills, Don Barrett, G. Russel, Ray Peacock and Sid Wicken.

Sid’s efforts were rewarded by not only a finish, but winning the Peter S. Chamberlain Trophy, for the best performance by a newcomer.

The second best newcomer in 1954 was Sammy Miller on his home built SHS (Samuel Hamilton Special) who was awarded the Ben Nevis Challenge Quaich.

The magnificent Peter S. Chamberlain Trophy was awarded to the Best SSDT Newcomer, a silver Rudge motorcycle scale model. Jack Wicken won this trophy in 1953, Sid would win it a year later in 1954. Photo: Trials Guru Archive.

1955 was however to be the Norman factory’s final year at the Scottish Six Days, the model was the B2/C with the Armstrong leading link front suspension.

Two teams were entered, the Norman Cycles Ltd ‘A’ team comprised of Sid Wicken, Ray Peacock and Jack Rees, team ‘B’ was Don Barrett, Gerry Mills and Clive Mills. Team manager was Karl Pugh.

Sid managed to finish with a Special First Class award on the Norman with the loss of 55 marks. The winner was Jeff Smith on the factory BSA Gold Star who lost 20 marks.

It was time for Sid to find another mount and living fairly local to the AMC factory, he had caught the eye of Competitions Manager B.H.M. ‘Hugh’ Viney. They had two things in common, both were good trials riders and both were pretty handy at golf with Sid regularly playing off a 4-6 handicap!

Viney supplied Wicken with a competition department prepared 350cc Matchless G3LC, registered as OLH722, which had been under the previous custodianship of Fred Hickman (in rigid frame specification), Gordon McLaughlan and latterly racing’s Bill Lomas who had the machine on loan, over the winter of 1954/55. Lomas handed the Matchless back when he parted company with AMC’s racing department. Wicken was to campaign OLH722 with the short-stroke engine fitted, until early 1957.

Sid’s works Matchless had a couple of modifications carried out by previous custodian Bill Lomas who had developed a trials machine for James. Lomas had footrests specially forged to be slightly further back than the standard fit items and Wicken liked this revised riding position so left them as they were. The front end had been steepened by the factory to give quicker steering achieved by heating the front frame up and pulling the down tube in towards the engine, resulting in a slightly steeper fork angle and removing about an inch from the centre of the primary chaincase and revised engine plates in aluminium alloy.

For the 1956 Scottish, Sid had the front frame break below the headstock near to Spean Bridge, so he drew out his pliers and set about cutting a length of wire from a farm fence to tie the Matchless back together again. That year elder brother Jack was riding number 121 on the factory Triumph and Sid was right behind with number 122 on the works Matchless, both finished with Special First Class awards, Jack managing to keep ahead of Sid by ten marks, the competition would have been intense.

The AMC competition department recalled OLH722 which was replaced with a fresh Matchless in April 1957, registered TXX515.

OLH722 was passed on to friend and team-mate Ted Usher for his last year riding for the factory. Sid’s works supplied Matchless machines were more than competition bikes, they were also his mode of transport to and from his workplace. He made full use of the motorcycles he was entrusted with.

Sid not only rode national trials but was also selected for the Great Britain International Six Days Trial twice, in 1956 at Garmisch-Partenkirchen in Bavaria and again in 1958 at the same venue riding for the GB Vase ‘A’ Team. Sid rode a factory prepared 500cc AJS (TGF706), issued with riding number V149 in 1956 riding in the GB Vase B Team, taking home a Gold Medal and a 350cc Matchless (VLF403) with riding number V226 in 1958, again a gold medalist. Both these machines were prepared specially in the AMC competition department at Plumstead.

As a prelude to the 1956 ISDT event, Sid and his team mates at AMC including scrambles rider Dave Curtis had been entered for a Austrian three day trial for practice, but it included a ‘night run’. Unfortunately, this information had not made its way to Plumstead and although the AJS and Matchless bikes were fitted with batteries to power the lights, they were not fitted with alternators to charge the batteries! The British riders spotted a fast German rider just before their lights dimmed completely and tailed him at close quarters.

Sid reckoned that his 1958 ISDT Matchless was the very best bike he had been issued with, he won another ISDT Gold Medal.

Sid Wicken continued to ride for AMC on the 350cc Matchless throughout 1958, albeit the Matchless trials team had been disbanded by the factory in late 1957 primarily to concentrate in trials with the AJS brand, headed up by Gordon Jackson. Matchless would still be represented in scrambles events headed by Dave Curtis.

Ted Usher had by this time retired from competition, handing back OLH722 to the factory and Wicken was offered a berth with Francis Barnett, as it was of course one of the AMC group brands.

The Francis-Barnett featured the unpopular, French designed, 246cc AMC two-stroke engine which was wider and more bulbous than the previous Villiers power plant it replaced and was not a popular machine which did not sell in large numbers.

Sid was entered number 93 for his last, the 1959 Scottish Six Days Golden Jubilee event with the Barnett, which had been prepared by Reg May at Comerfords, Thames Ditton. With six entries resulting in six Special First Class awards, it was an unblemished record for Sid Wicken in the Scottish Six Days.

Sid Wicken’s SSDT tally was as follows:

Year – Riding No. – Machine – Result

1954 – 14 – 197cc Norman – 51 marks – Special First

1955 – 75 – 197cc Norman – 55 marks – Special First

1956 – 122 – 347cc Matchless – 83 marks – Special First

1957 – 153 – 347cc Matchless – Special First

1958 – 156 – 347cc Matchless – 31 marks – Special First

1959 – 93 – 250cc Francis Barnett – 45 marks – Special First

Sid was no stranger to two-strokes, having campaigned the Norman machines in 1954-1955, but the Francis Barnett frame broke on the Friday, so it was a coat hanger wire that came to the rescue this time to get through the Saturday’s run back to the finish in Edinburgh. In fact Sid was plagued with frame failures when on the Francis Barnett, he had it happen three times on three different machines supplied by the factory.

Having given up top flight trials riding in 1959, returning the 250cc Francis Barnett to the factory, Sid had a short lived return, when he ended up with a 250cc Greeves in the mid 1960s. The machine was taken as part payment for a submission of drawings Sid did privately for a gentleman’s planning application. In his later years, Sid maintained an interest in trials through his son’s Stephen and David and also made the annual pilgrimage to Fort William to spectate at the Scottish Six Days Trial, right up to his death, having watched for the last time in the May that year. He was 85 years old and passed away on 24th July 2014.

John Edward Wicken, known as ‘Jack’ was born on 3rd September 1927 in Woolwich with brother Sid, born two years later. As mentioned earlier, Sid senior had the motorcycle and sidecar combination and as kids, Jack would sit on the back of the bike and brother Sid would be in the sidecar with their mother, Beatrice or ‘Beat’ as she was known. Both were introduced to bikes at a young age. Jack always maintained that his driven nature came from his mother, Beat was a force of nature, a serious character and massively proud of her two boys.  The brothers were very close, life-long friends and very competitive. The second world war was declared on Jack’s twelfth birthday.

Jack Wicken was called up for national service in 1946 and spent twenty-two months in the Royal Navy, he became an Ordnance Artificer fourth class. He served on HMS Norfolk which had been involved in the sinking of the German battleship ‘Bismarck’ during the war and the post-war ‘cruise’ he was on took him out to Africa.

HMS Norfolk, the ship that Jack Wicken served on.

Jack had said that when they fired her big guns, the ship shook. However the highlight of Jack’s navy service was not looking after those guns, it was that the Norfolk’s football team, of which he was a striker, winning all twenty matches while he was on board. He couldn’t wait to get back home to become a footballer.  Jack was released from the navy in April 1948 but instead of football, Jack became a trials rider. It is thought brother Sid had got the trials bug while he was overseas which was why Jack decided to give it a go. Sid soon after went into the army for his national service.

Jack Wicken was training as a toolmaker in Woolwich at Pitter Gauge and Precision Tool Company, and had a pickup to transport the bike to trials. Jack would finish work at 5pm on a Friday and that night drive up to Scotch Corner in North Yorkshire, sleep the night in the cab, and then ride in a trial the next day. Then be back at work on Monday morning.

As far as riding for Triumph, Jack’s wife, Marjorie who was a secretary, wrote the letter which got him a works supported ride. The most remarkable thing about the Wicken brothers trials success was that they were born and brought up in South East London surrounded by houses, not countryside and hills. The only rocks would be found in garden rockeries! Jack and Marjorie had two children, Carol born in 1957 and Trevor in 1960.

There are many reports of Jack’s successes, the most notable being the Welsh Two Day in 1953.

Welsh Two Day Trial results from 1953.

Triumph Engineering made full use of the publicity surrounding Jack’s Welsh victory. Also the two international Six Days Trials at Garmisch-Partenkirchen in Bavaria, Germany in 1953 and Czechoslovakia in 1955.

At the Bavarian ISDT, Jack’s 500cc Triumph twin was suffering from a sticking throttle slide, to attempt to control his machine, he used the ‘kill button’ on the end of the Lucas magneto, otherwise it was almost flat out all the way, such was Jack Wicken’s determination to succeed being paramount against all odds.

Bernal Osborne’s report in the Motor Cycling of 22 September 1955:

Despite weatherproofing equipment, it jammed quite a few rider’s throttle slides and both Wicken and Alves were beaten. Fearful of stopping, Wicken continued as best he could with the carburettor slide half open, using the ignition cut-out to control speed, but nevertheless he lost much time.” [2]

Jack Wicken overcame the challenges of that very wet ISDT in Czechoslovakia to bring home a Gold Medal for his efforts in 1955.

Jack also won several special first class awards at the Scottish Six Days Trial.  Jack’s first Scottish was in 1953 and was rewarded by winning the P.S. Chamberlain Trophy, for the best performance by a newcomer, a year later brother Sid would win the very same trophy.

Presented to the Edinburgh & District club by the directors of Rudge Motor Cycles, the P.S. Chamberlain trophy for the Scottish Six Days was a scale model silver Rudge ‘Ulster’ four-valve head port motorcycle on a wooden plinth, which had real rubber tyres, control cables and a drive chain with individual links which worked. It was in itself a work of art.

Jack Wicken retired from trials riding in the latter half of 1957 when Triumph took back his 498cc twin PNX661, and wanted him to ride the much smaller 199cc Tiger Cub, which was not to his liking.

Jack was never defined by trials riding alone, he was very proud of what he achieved, but he lived in the moment but there were other sports which he came to love. Although there was a brief return to trials in the 1970s when he and Sid had one last fling at the Greybeards Trial, they were more likely to be found on the golf course together. 

Jack had taken up golf when he stopped trials riding and got his handicap down to two. In the 1970s he captaining one of the Kent teams. He also skied, rode horses and also sailed. He and brother Sid played a lot of golf in their latter years, but during the winter Jack would be found on the ski slopes of Westendorf in the Austrian Tyrol, whenever the opportunity presented itself.

Jack Wicken owned and ran his own light engineering companies for forty years. Starting with All Type Tools Ltd in Woolwich which he started as a worker’s cooperative with twenty other men in the early 1960s. In the 1970s, he left All Type Tools when he bought Wheeler and Clinch Limited, a tool makers business and Glyndon Plastics Limited, which was a plastic injection moulding business, which was also based on the Woolwich Industrial Estate. At one time he had forty people in his employment.  Jack retired when he sold the companies upon attaining 70 years of age, but for the last five years before stopping work, he would head off skiing at the drop of a hat. He always stayed at the same hotel and just before getting in the car to drive to the ferry, he would call the owners and tell them he was on his way. He was such a good customer and friend they always found him somewhere to stay, in the staff flat on one occassion and his photo hung above the bar where he enjoyed the apres ski.

Jack Wicken passed away in the November of 2012, aged 85 years.  Once he couldn’t play sports, he didn’t see a lot of point to life, he needed the competition.

So there we have it, two very different brothers who took up the very same sport, both receiving factory support and machinery, both competed at high level observed trials and speed events. Both equally determined to win and to beat each other in the process. Never giving the other any quarter, but still brothers until the end. The sort of rivalry that we don’t see anymore in our society. The Wicken brothers brought home the spoils of competition and their results did the talking.

Trials Guru’s John Moffat: “I never had the pleasure of meeting Jack Wicken as the opportunity didn’t arise, however I had the great pleasure of meeting his younger brother, Sid on more than one occasion. The first time was at the Ben Nevis sections during the 1986 Scottish Six Days. I was spectating and I happened to notice the gentleman to my left was wearing a Barbour jacket with a Union Jack embroidered badge on his left shoulder. I asked him if he rode in the ISDT at some point. He replied, “Yes I did on more than one occasion and I rode this trial many times.” I recognised him from some old SSDT programmes I had collected, looked at him and said: “Are you S.R. Wicken by any chance?” to which he smiled and replied positively, “Yes I am S.R. Wicken!

We conversed for a while and then I said to him that my family owned an ex-works Matchless. He then asked me what the number was, as I had told him it was Ted Usher’s former steed. When I told him that the registration number was OLH722, he quickly and abruptly said: “That was my bike!

From that moment on, we had something in common and we communicated many times, the following year he even brought up some old photos of him on OLH722 for me, which I had copies made and still have. Sid also told me how his works Matchless was prepared and about the various modifications from standard.

Sid Wicken came across as a very knowledgeable and positive thinking gentleman, someone that didn’t let too many things bother him. The type of man that looked for solutions and implemented them. Probably that is why he was so successful in the sport and warranted factory support for so many years.”

AJS – one that got away

There has always been a desire by enthusiasts to get their hands on factory machinery. The AJS and Matchless machines were one and the same, except for minor details and were brands that lesser lights sought to own.

A number of AMC trials bikes were released into private ownership after use by the Plumstead competition department, but only a few really ‘escaped’. One such escapee is the 350 Matchless G3LC the father of Trials Guru’s John Moffat purchased, OLH722. This was achieved by a single telephone call to the factory competitions department of AMCs in 1957. It was an ex-Ted Usher/Sid Wicken machine that had been in both long and short-stroke powered format in its four year period of use with the Plumstead factory riders. Similarly, the Matchless OLH723 which Usher also rode, was also released for sale in 1957 but released as an AJS and ridden in that year’s SSDT by Thornaby’s  Robin H. Andrew, whereas OLH721 had been Artie Ratcliffe’s factory 1954 SSDT winning mount when in rigid frame form.

OLH722 had past through the capable hands of Fred Hickman, Gordon Mclaughlan, Bill Lomas and Sid Wicken before ending up with Usher as his last factory supplied machine in 1957, just prior to the Matchless team being disbanded. The machine is still in the Moffat family, but that is a different story.

This is the story of another AMC factory machine that got away. A motorcycle that hasn’t been stored away or kept in a museum, but one that has continued to be used in anger as it was designed and built for – competition, and has won in the process.

WJJ580, where are you?

We set about tracking down the story of the 1959 registered AJS 16C with the index number WJJ580, one of a batch of similar machines used by the factory. Built as a long-stroke 350, it eventually became a 410cc variant which the factory wanted to try as a bigger bore machine. These special motors ranged between 401 – 420 capacity.

The discovery of WJJ580 opened a veritable pandoras box of information. With Trials Guru on the case, we find that there were three such machines made available to riders around the same time period.

The competitions department at AMC had been experimenting with competition short-stroke motors as early as 1956, these were issued to their factory supported riders replacing their long stroke units. Production short-stroke trials models would not be available until six years later, and a full year after Comerfords asked for Jackson replicas to be built, following his 1961 SSDT win. The first short-stroke would be the Matchless in 1962 followed by the 1963 AJS ‘Expert’ 348cc models.

Factory numbers:

The factory registered their team machines in their name ‘Associated Motor Cycles’ with some AJS machines being registered as a Matchless. One such machine was the 1961 AJS used by Mick Andrews from 1962-1964 which was registered as a Matchless 347cc as 644BLB.

Gordon Jackson told Trials Guru: “When the factory disbanded the Matchless trials team in 1957 to concentrate the brand in scrambles and motocross, they asked me to use a Matchless tank on my works bike just to keep the brand name going in trials, but in reality the bike was simply my AJS with the different tank fitted“.

In September 1959, AMC trials models brought with them the bespoke trials frame with a much lighter and slimmer rear subframe, and a swinging arm taken from the lightweight road machines of the era. The previous competition models had the wide set rear subframe accepting firstly the Jampot rear suspension, and then latterly Girling suspension units with bottom clevis mounts.

With the launch of the ‘new’ trials model, the factory had registered a batch of 350cc trials models for their retention by the Competitions department under the watchful eye of former rider, Bob Manns. These were all registered consecutively on 1st January 1959 as WJJ578/579 and the subject of this article, WJJ580.

The ever helpful Don Morley, professional sports and news photographer, and author of many books on motorcycling, looked up his records for Trials Guru and confirmed that Roger Kearsey had been issued with WJJ578 as a Matchless as did Ron Langston in 1960, Cliff Clayton with WJJ579 and Gordon Mclaughlan with WJJ580; the machine we are featuring.

Don Morley told Trials Guru: “The motorcycle manufacturers worked under the same legislation as private purchasers, in that they had to pay purchase tax which started in 1940 and went on until 1973 when it was replaced by Value Added Tax, when registering any motor vehicle back then. This was the main reason why they simply replaced the machine between the number plates on more than one occassion. Triumph however didn’t seem to do that“.

Cliff Clayton rode the Scottish Six Days Trial in May 1959 on ‘579, but it did not have the complete new style frame at this time, instead it had the factory 1958 ‘prototype’ rear subframe heavily altered at the top damper mount and used a Girling unit with the alloy clevis type lower mount mated to the old style swinging arm. It also utilised the heavy full width alloy rear hub, but the 1959 style 5.5 inch half width front hub which was from the 41′ WD G3L military machine. The fuel tank was blue with gold lining and the AJS monogram. A departure from the traditional black/gold combination. The new rear 5.5 inch trials rear hub would be introduced in the September 1959 and eventually all WJJ registered machines would be retro-fitted with the new style frame and lighter wheel hubs by the competitions department.

Morley: “I do remember having a ride on WJJ580 during a visit to the Isle of Man some years ago“.

AJS, the brand:

Probably the most famous AJS trials machine of all time is that which was used by Gordon Jackson to win the 1961 Scottish Six Days, losing a solitary one mark, the lowest ever recorded score. It was registered in December 1960 as 187BLF and is now owned by the Sammy Miller Trust, having been re-discovered in 2010 by Miller and positively identified by Jackson. 187BLF had never left the UK, this was contrary to popular belief.

Factory rider, Gordon Blakeway who had ridden for Ariel and Triumph, took over 187BLF when Gordon Jackson retired from trials in late 1962.

Gordon Blakeway told Trials Guru: “I rode 187BLF not as a short-stroke, but as a long-stroke. The bike was changed by the factory before I received it and Hugh Viney reckoned because I had ridden the long-stroke Ariel, then a long-stroke AJS would suit me better. I was slightly disappointed at this because I had been keen to have Gordon Jackson’s sharper short stroke motor“.

Blakeway continued: “When the factory eventually closed its doors in 1965, they asked me what I was due in expenses and I said it was about £55. I asked what they were going to do with 187BLF and they said it was for sale and they wanted £100 for it. I bought it, handing over the balance of £45 and about three weeks later I sold it on for an acceptable profit“.

It had been universally believed that 187BLF had been exported to Australia in the 1970s, even Blakeway believed that this was the case. However that was most likely to have been confused with the exportation of 644BLB, the 1961 registered Mick Andrews’ machine (1962-64), which Cliff Clayton also rode in the 1961 SSDT as an AJS, although it was registered as a Matchless.

WJJ580, the beginning…

Looking at the original buff log book, WJJ580 was registered as a 59/16C AJS on 1st. January 1959 to Associated Motor Cycles Ltd at 44 Plumstead Road, London SE18 listed as a ‘350cc’. However, it would not always be ridden as a 350 but as a 410 sometime later.
The AJS was retained by the AMC competitions department until 1963 when it was sold into private ownership to a Mr. Stone in Birmingham. After 12 months, he sold it to a Mr. Hopkins of Swansea, Wales.

The machine’s colour scheme was originally recorded as blue/black, being a blue tank and black frame, which was by then a colour option on production trials models.

Trials Guru tracked WJJ580 down to its’ current owner, Ian Harland who lives in the Isle of Man, he is the father of James Harland, a past winner of the Pre’65 Scottish on a Triumph twin in 2013.

Ian Harland: “I bought the AJS from the rider/dealer Bob Gollner of Denmead, near Waterlooville, Hampshire in 1989, it had been restored for him by Peter Pykett and I think he won the Talmag Trial on the bike“.

Harland: “The AJS has a lot of history in that it had been built within a small batch of similar machines for the factory riders. One of which was Gordon Mclaughlan who rode it in the 1960 Scottish. Unfortunately, it was believed that Gordon didn’t get on with the 410 motor and sent it back asking for a long-stroke 350. He was then allocated 164BLL which he rode until the factory closed its’ doors and the AJS team was finally wound down. Gordon retained the AJS, 164BLL for his own use after that“.

ian-harland-wjj580

Harland: “According to the original buff log-book WJJ580 was first registered as a 347cc machine. If this dislike of the over-bored mtor is correct it happened around 1960-1961. The reason the crankcases are stamped ’61’ is because a replacement motor would have been fitted. Apparently, the conversion to 410cc involves long stroke 350 crankcases and an 74mm bore. So to change from a short-stroke 350 to 410 involves a complete engine change, not just the barrel and head. Presumably, the change back to a 350 involved the installation of a new engine in 1961 which is still in the bike today. I met an ex-AMC competitions shop employee at the Manx Classic a few years ago who remembered some of this. I understand that Malcolm Adams from Leeds owned the sister machine, WJJ579 the ex- Cliff Clayton bike”.

Gordon Mclaughlan was issued with WJJ580 and rode the 1960 SSDT carrying the riding number 147. It was obvious that the short-stroke motor was used at this point, evidenced by the matt black rocker-box which indicated an ‘elektron’ item. Elektron is a magnesium alloy made by the Magnesium Elektron company for AMC, which it used from the early 1950s. These componenst were usually retained by the factory when machines were sold to be used on other machines. It had the integral push rod tunnels. It also sported the long down-swept exhaust system with the short silencer. ‘580 was also fitted with the new style 14 inch Girling rear damper units which bolted on to bosses on the frame and swinging arm. Steel wheel rims were still being used at this time with the standard 21 inch front and 19 inch rear. Dunlop ‘Trials Universal’ tyres were fitted to all the team bikes.

Gordon Mclaughlan spoke to Trials Guru, confirming some points raised by Ian Harland: “It’s a long time ago now and I have read a fair bit about my factory bikes over the years and it would appear that people know a lot more about them than I ever did! I suppose I was just too busy riding them to note down all the important facts and figures about them. However what I can remember is this. My bikes were always prepared by the works. I used to take whichever bike I was riding to Thornaby railway station and send it to the factory at Plumstead. They would fettle the bike and send it back, wrapped in cardboard and taped up to protect it in transit and I would go and collect it from the station.

I remember that the factory gave me a spare fuel tank that was a Matchless one, so that I could enter some trials with the AJS as a Matchless and I would cover over the AJS emblem on the timing cover.

I really liked the long-stroke motor as the sharp motor that Gordon Jackson used was just a bit too quick for my liking. I recall that some of the engines in my bike were as high as 420cc or at least that is what the factory told me. It was to try and win the 500cc cup at events on what was an over-bored 350.

I did ride WJJ580 for a year or so, before the factory asked for it back to do some work on it and back came 164BLL, that would be around late 1960, early 1961. It was before Gordon Jackson won the SSDT and we were given similar machines. I used 164BLL until the factory shut down, I was due eighty-five pounds in unpaid expenses and I was given 164BLL as payment. I kept it for quite a few years and then sold it as I was too busy to ride it when I was building my business, Gordon Mclaughlan Motors in Guisborough. We sold AJS motorcycles and Lambrettas to start with then I started selling second-hand cars until we became Morris agents which became BMC and then Austin-Morris, British Leyland and finally Rover until I retired“.

Trials Guru research revealed that Gordon Mclaughlan’s 164BLL was registered on 1st. January 1961 as a Matchless, even although it was built as an AJS and used primarily as such, and as a 350cc. I mattered not that Gordon’s AJS was actually registered as a Matchless, because the MOT test which commenced in 1960 was originally a ten year test, reduced to seven years in 1961. The factory didn’t retain machines much above three years from the date of registration.

Mclaughlan continued: “I did ride one of the first Pre’65 Scottish trials at Kinlochleven on a replica AJS I had built, I think that would have been around 1984. I enjoyed my time riding for the factory from 1954 after a couple of years on my own Norton 500T. The first AJS I received was a rigid, but I can’t recall the registration number of that bike, if anyone has any photos of it I’d be keen to see it. I know it wasn’t an ‘AJS’ private registration number as Gordon Jackson, Hugh Viney and Bob Manns had those.

Hugh Viney was our team manager, he was quite an aloof, reserved character, a rather serious man.

It’s amazing how many ex-works bikes were sold off by the factory after use. Ted Usher’s bike OLH723 ended up near to us, a local lad from Thornaby called Robin Andrew bought it in 1957. He was a fairly good local club rider“.

Sadly the factory machine 164BLL issued to Gordon Mclaughlan, was completely destroyed in the fire that destroyed many historic motorcycles at the National Motorcycle Museum at Bickenhill, Solihull on 16th September 2003.

Ian Harland continued the story: “When I bought WJJ580 the engine wasn’t the sweetest, it was actually very ‘rattly’. Martyn Adams, then based in Brighouse, West Yorkshire re-sleeved the barrel and found a new 7R piston for it. The motor has run ever since in many trials over the years ridden by myself including a number of Pre’65 Scottish, most Manx Classics, Talmag, Mons in Belgium etc. I’ve retired from trials now so the engine top end is again being rebuilt, the barrel being re-sleeved again by Martyn, now in Adelaide, Australia“.

Watched closely by SACU official Jim Birrell (standing with cine-camera) and Ralph Venables (seated, top left) Being factory prepared, it is fitted with the tommy bar front spindle nut and the compressed air bottle mounted on top of the alloy primary chaincase. The front forks have rubber inner tubes to protect the external fork springs. You can just make out the ‘prop stand’ bar strapped to the front frame down tube. This slotted into a tube which was welded to the front engine mount on the near-side. This complied with the SSDT regulation that the machine “must be fitted with a stand or the penalty would be 5 marks per day”. Mclaughlan was subsequently issued with 164BLL – Photo couresy of Ian Harland

Works issue:

WJJ580 was used in effect as the works ‘hack’, a machine that would be allocated to various riders who had either expressed a wish to ride for the factory or were chosen, some ‘selected’ by the well-known doyen of trials journalism, Ralph Venables.
Venables would effectively ‘scout’ for the factories as he had the ear of the competition managers, two of which were Hugh Viney and Bob Manns of AMC.
History records that Dave Rowland was ‘selected’ in 1961, prior to being snapped up by BSA, and was issued with 580 when he had been at Bordon doing his army national service. However it was not a happy arrangement and Rowland sent the machine back as he didn’t get on with it. But in his customary style, Dave sent a polite letter with the returned machine in 1962, thanking Hugh Viney and the factory for allowing him to try it over a period of time.

Taken directly from Ian Harland’s scrapbook on WJJ580, we have an image of the late Dave Rowland on the AJS when he was enlisted to the army during national service in 1961. We can see that the machine has the late type frame and swinging arm and long rear mudguard loop Please note: This image is copyright and was used by the late Ralph Venables in his ‘Ralph Remembers’ column in T&MX News at one stage.

Roger Kearsey from Upwaltham, Sussex who competed with the Matchless WJJ578 for a spell went on to ride for Royal Enfield.
Eric Adcock of DOT fame also rode WJJ578, but eventually sent it back, preferring to stick with the two-stroke DOT.

WJJ578:

Eric Adcock spoke with Trials Guru and provided photos of ‘578 that he had taken, plus the letters that he received from Hugh Viney, the competition manager at the AMC factory. Eric is still heavily involved with the sport and is a Director of North Western ACU and is their Permit Secretary and Treasurer.

Eric Adcock: “I received correspondence from Hugh Viney, the competition manager at AMC and I was sent WJJ578 to try out”.

Adcock: “I started in trials on a BSA Bantam in 1951, then on to a Francis Barnett and eventually on a DOT in January 1954, with a short spell on a Triumph Cub in 1958 which I had been sent by Henry Vale at triumphs, but couldn’t get on with it at all, so I sent it back. The Matchless I got on reasonably well with and quite liked it, winning an event in the process, but it was a bit too tall for me. I had the bike about three months before I sent it back to Plumstead, deciding to stick with DOT Motorcycles“.

Adcock: “… as it was a warm and pleasant place to clean them and work on them until I got married”

Adcock: “I took some photographs of WJJ578 when I had it and held on to them, along with the correspondence from Hugh Viney, I hope it brings back memories for your readers“.

 And so back to WJJ580 – Harland’s machine that got away:
sloc-manx-classic-2

In 1962 it was the time for the factory to move on the AJS, WJJ580, with new stock having been taken from the production line and retained by the competitions department, headed by Wally Wyatt.

Factory mods…

This was how it was done by the works: The machines would be selected by dispatch staff from the production line and the frame and engine numbers were all noted in the production ledgers as being retained by Comp Dept. These selected machines would be wheeled away to the Competitions department. The machines would be registered in the company name and then stripped down and modified by the competition staff with lighter components replacing standard parts as required. One such item was the primary chain-case, the factory had these fashioned from aluminium alloy instead of the standard steel pressing with a separate, detachable clutch dome also fashioned from aluminum alloy. This practice had been carried on from the immediate post-war years.

Around 1955, the practice was to steepen the steering of the standard trials frame by heating up the frame tubes and forcing down the headstock, this also required new engine plates in dural to be made up as the gearbox became closer to the motor and a shorter primary chaincase was also fabricated out of alloy. The result was a sharpening of the steering which the factory jockeys preferred.

Fuel tanks could be altered to sit on the machine closer to the steering head or otherwise to riders preferrence. Usually the area of the tank where the riders knees would make contact would have the paint polished off and abbreviated lining used.

Inside WJJ580…

The replacement 1961 stamped engine in Harland’s bike is definitely non-standard. The motor uses a 8:1 high compression piston and is a forged item as used in the AJS 7R racing motors. The valves are much bigger than the standard AJS 350 single utilises. It also has much more power than the standard 350 motor produces.

Around the year 2000, the original frame cracked at the headstock. The AMC trials frames were susceptible to this type of occurrence and it’s amazing it lasted so long. An Andy Bamford from Fleet frame kit was obtained which has been used ever since.

Harland: “I still have the original works frame which one day I’ll get repaired. These bikes are like ‘Trigger’s broom’.
I rode my son James’s 500 AJS in the Pre’65 Scottish in 1999 and l loaned WJJ580 to my good friend, Giovanni Dughera from Turin who was a works Ossa rider in the 1970’s”.

WJJ580 partially disassembled in 2016 to have a new liner fitted to the barrel by Martyn Adams. This frame was made by Andy Bamford in 2000, but Ian Harland still has the original frame set which will be repaired in the future. Note the alloy front brake plate, a special factory item, not the Comerfords version. The central alloy oil tank was a period modification used by the factory and subsequently marketed to private owners by Comerfords of Thames Ditton. All late model AMC trials machines from 1959-on used the bespoke trials frame and lightweight style swinging-arm and the 1 1/8th inch forks with the alloy top yoke.

Martyn Adams, formerly of Serco in Brighouse, now living in Australia and trading as MDA Motorcycle Engineering picks up the technical details: “I reconditioned this engine over 25 years ago and don’t think there is too much to say. However finding a piston for the engine 25 years ago was an issue, as the bore size is 74 mm, not the usual 69mm. At first we thought it was an AJS twin piston, but not so, as the piston is a forged type and not the cast type. We then realized the piston is from a 1954 specification AJS 7R, not the readily available short-stroke type of 75.5 mm“.

barrel-m-adams

Adams: “This is the reason we recently re-sleeved the cylinder as the piston was still in very good condition but has now been machined to take a modern oil control ring. Ian believed for years that the motor was a 410, but I think the crank is a standard 93mm stroke, which would give a capacity of exactly 400cc“.

Adams continued: “So I suppose the motor is really quite special as it’s a pretty unique mix of factory parts. Ian also has a another bike with a special short-stroke engine that I made a crank for and is very similar to the short stoke Ariels we call her the big bang motor“.

barrel-m-adams-2

Adams added: “I haven’t checked, but would reckon with the domed piston and 74 mm bore, not 69mm, the compression ratio will be around 9:1. This is quite high for a trials machine. The cylinder head from memory has the later valves from the short stoke head with big inlet with a 5/16 inch stem and small head exhaust valve with a 3/8 inch stem. As I said a real mix of factory parts“.

So at least WJJ580 escaped the fate of many factory machines that were broken up for their parts and it was put to good use. To be ridden and competed on, very much in the spirit in which they were all designed and built.

WJJ580 certainly was – One That Got Away!

The numbers game…

The AMC factory road registered all its ‘road test’ and works retained trials machines locally in the Greater London area. The ‘XF’ index mark for example was London County Council, used immediately post second world war. The exception was the ‘GK’ index mark, as it was London South West area, whereas the factory was based in being Plumstead SE18 London. It is safe to say that all AMC factory trials machines were all London registered.
