I wanted a vintage 50cc racing bike but didn't want to pay for an original or try to source rare vintage parts. the base bike was a 78 pa50I that in the end, I used the engine cases and gearbox. The frame and subframe are 3/4" chromoly steel, fork tubes are a yamaha pw80, and front brake off a kawasaki kz400. The radiator is from a ninja 250 and running a bosch pump. Frame and subframe are powdercoated in a "safety orange" and the bodywork is a urethane base/clear in grabber blue.
