Bultaco Special Sherpa 1983


In an attempt to keep at the cutting edge of the sport but with a factory in serious financial trouble, Yorkshireman John Reynolds rode a special Comerfords Bultaco 340 in 1983 which had been built by Reg May on a freelance basis. It had some innovative features. Reg had managed to move the swinging arm pivot very close to the final drive sprocket. This was achieved by mounting the swinging arm pivots on two independent mounting ‘bobbins’ mounted on the frame. The swinging arm spindle was effectively dispensed with as was the rear engine mount assembly.

A special snakey exhaust system was used with the back box lowered to the footrest area on the off-side of the machine using modified Bultaco components. The swinging arm was a modified Bultaco Pursang item on the final version.

Enthusiast and journalist, Stefano Bianchi from Milan had the opportunity to buy this very special machine and has allowed Trials Guru to feature some photographs taken by Stefano.















With special thanks to Stefano Bianchi for allowing Trials Guru to feature this very unique Bultaco 340.

El Donkey, the nick-name given to Skipton rider James Moorhouse’s Bultaco Sherpa 340 will be ridden in the forthcoming Scottish Six Days Trial (2-7 May, 2016) in Lochaber.

Allocated number 255 this year, the machine suffered engine failure on the tough Tuesday run which had stressed the 35 year old machine to it’s limit.

Moorhouse had to retire as the motor had suffered irreparable damage, but vowed to have the machine rebuilt for 2016.

James also has his own amusing nick-name which is ‘P***-Tank Frank’.

The SSDT ballot was run and James was successful in his entry. Last year he rode number 181 and the elderly Bultaco caused great interest with SSDT supporters, many who remember similar machines being ridden in the 1980s.

James’s usual riding companions, Boyd Webster and Alan Mudd are not far away at numbers 247 and 248.

Here is a full list of entrants:

Altered top clamp to change the rake. HFS internals in the front forks. I’ve re-lined the hubs fitted Rockshocks. Over sized frame tubes, tube-less rim on the rear. Right to left rod for brake instead of cable. Fat-bars with 6 inch rise. Electronic ignition. Lengthened front part of the exhaust pipe. Made straight through and narrowed the club-foot rear exhaust. Fitted a Keihin flat slide carburettor. Smaller seat“. Kind regards see you all in Fort William – James Moorhouse, Skipton, Yorks.
