Thanks Bill, You are most correct, When I looked through some of Reg's photo albums, on an earlier photo, with his bike still in it's original road trim, a hand written message along side the picture shown of him racing at some track in the UK, said that the handling was" Somewhat suspect". When I asked him about this, he answered that once he had changed the front and rear springs, and put better shockers on plus the hydraulic damper, that this transformed the bike no end. The other mods were mostly to aid in ground clearance.....But he also said the change to concentric bushes, and thereby changing the trail, made a big difference as well. Gave quicker steering he said........Greg.
