Ahead of it’s time, we are carried back to 1978 when photo-journalist Mike Rapley snapped this unique monocoque framed 325cc Bultaco at the Welsh Trophy Trial.
The top frame tube carrying fuel it bears a strange resemblance to machines we use today.

Unfortunately, Mike Rapley could not recall who built it, who rode it or if it still exists, but we do know someone that would like to own it! Then, thanks to a Trials Guru reader, we discovered that the owner/creator was from Kiddermister, England, called Phill Smith.

Have a look at the detail shot and judge for yourself! It was a forward thinking concept using the tried and tested 325cc Bultaco motor, plus some Bultaco components, such as the front end and wheels.

I seem to remember Steve Wilson playing around with this concept
I think its Steve Wilson.
I have a vague recollection of Duncan Macdonald producing a Bultaco special after the Ossas but whether this could be it I am not sure. It does have more of the Steve Wilson signature about it certainly.
I think the duncan mcdonald one was rivetted certainly this looks more steve wilson
I too remember this from the time and sure it was a Steve Wilson prototype
I thought Steve Wilson also, especially using those plastic tubes as chain guards but it doesn’t look like Steve riding it
I thought Steve Wilson when i saw it, especially the plastic tubes for chain guard, but it certainly doesn’t look like Steve riding it
the duncan macdonald bulto was aluminium and was rivetted just like the ossa s beforei .i rode with farther and son had some good times with the macdonalds they had a company in macclesfield and made vf muddgards vf stood for vacuum former’s and t
hay made all sorts of parts for bikes
Think like Tony it was from the joint Steve Wilson and Colin Tippin ( Frazer Emporium )in Redditch.
Had a chat earlier this week about the bike and Arthur Williams commented “now owned by john Collins acu man….but steve Wilson built that” I think you know one or both of the above, John Moffat, so perhaps the mystery might be solved once and for all with a but more info from them.
