It represents yet another trials bike from the fertile mind of Yorkshireman Peter Gaunt and was marketed by Allan Jefferies Motorcycles of Saltaire, near Bradford.
The basis was a Honda XL250 trail bike which was supplied complete to Gaunt who stripped it right back to the bare frame which was modified for steering head angle, the four-valve four-stroke engine lifted and the rear sub-frame was removed and a slimmer, lighter one fabricated.
Peter also put a lot of work into the thin gauge steel fuel tank, cutting a strip out of the centreline to make it narrower and also making cutouts to fit around the cylinder head after the engine was raised in the frame
The original main frame, front forks and wheels were utilised but the rest of the stock kit like lights, wiring, battery, ignition lock, seat, mudguards and exhaust was dumped and Peter added VF mudguards and his own exhaust.
The stock carb was also binned as it was a bulky piece of kit and a 26mm Amal carb substituted.
The ready to run weight was around 230lbs which was around 30 lbs more than the two-stroke opposition which is quite a chunk but it was certainly capable of winning a National trial in its day.
Don’t know how many were made – around 20? – which makes it quite collectable….
