Fc's S2RR-Seeley type frame can be used with the H1R or standard H1 engines. The H1 frames, whether a factory "R": frame, stock or even period modified had problems regardless of the rider and\or track conditions. The FC S2RR chassis kit solves all of the original handling issues while retaining a period correct style. FC also offers an exhaust system designed for your engine build and retains exceptional ground clearance. This bike was also fitted with one of our alloy fuel tanks. The pictures shown demonstrate 2 different builds. One on a R motor and the other on a standard motor both of which have been fitted with a dry-clutch.
