Providing direct output to your engine’s transmission, the 4-Stroke Clutch Flyweight is a vital engine component. Located on the engine block and connected to the bell rotor, the flyweight will move and expand when you twist the throttle grip. This results in the flyweight making contact with the bell rotor and thus causing your bike to propel forward.
