Designed to propel your bicycle engine, the 4-Stroke 10 Tooth Drive Sprocket is a crucial transmission component. Located on your 4-Stroke 5G Transmission and connected to the Transmission Output Shaft and 415 chains, this component rotates as you twist the throttle grip. This results in the transmission of rotational energy from the 4-Stroke 10 Tooth Drive Sprocket to your rear sprocket in order to move your bike forward.

Most 4-stroke bicycle engine kits have 10 tooth drive sprockets. This drive sprocket threads on to the end of the 4-stroke transmission's drive shaft, located on its transmission and is locked in place with a clip (clip not included). Perfect for all Huasheng 142 and 142F engine kits and transmissions.

Note: 4-stroke drive sprockets are compatible with 415 chains. Some filing of the teeth may be necessary, as some chains skip if teeth are too long.
