The output shaft on a motorcycle is a crucial component of the transmission system that transmits power from the engine to the rear wheel. It converts the rotational motion of the engine into the drive force necessary for propulsion. Typically made from hardened steel or alloy, the output shaft is designed to withstand high torque and stress while ensuring smooth and efficient power transfer.

Suitable for 125cc 4-Stroke scooters with an engine number beginning with 152QMI.
