The gearbox is a Petty PGT 5 speed, which I bought from Ray Petty in the 1970's. I have used a replica Manx gear lever linkage. This does mean that the bike has to be bump started, but the light weight of the bike makes this fairly easy. If a purchaser wished to fit a kickstart gearbox, I have an AMC box which I could supply, with various gearing options, but it would mean getting a new exhaust pipe bent, and having a folding footrest etc. I have fitted a four plate clutch, and a standard primary chaincase.
