The PW50 is a 50 cc two-stroke dirt bike that is intended to introduce children to the sport of off-road motorcycling. Whereas standard dirt bike controls are difficult for even a fully-grown adult to learn, the PW50 is fitted with an automatic clutch that allows a young rider to concentrate on learning how to steer his motorcycle. The clutch system is similar to a drum-style brake and includes an outer clutch hub and an inner clutch assembly. A failing clutch will present itself as a distinct lack of power regardless of how far the throttle is open.
