Flat-CR (FCR) Carburetor
Originally designed and developed on world-class Superbike racing circuits, the Flat-CR carburetor broke new technological
ground with an innovative flat-slide throttle valve that rides on roller bearings. This practically frictionless design allows for
much lighter throttle return springs and a finer degree of power control for riders. Produced with the highest level of
technology available, the Flat CR has proven its advantage with race wins around the world.
