Doc,
Beats me why somebody didn't attempt to make a trials bike out of the 185 Suz bored 2mm to 200, to rival the TY175/Cota 172. Shorter swingarm, rearset/raised pegs, slimmer tank/seat etc
I know the Gaunt 120 was a little earlier than the TS185 was released, but it surely would have made a much better bike I would have tho't. Maybe a Gaunt replica w a 185/200 motor would be a better mouse-trap!
Could even use the 10speed TC185 motor if you could remove the electric starter, run a regular flywheel ign & slim the LHS ign cover. Yeh I know, lots of work, but even the TS185 motor would make good basis for trials engine w its mild port timing & compact/lightweight size I would have thot.
