Description
Keeping your KYMCO machine operating at its best demands close attention to high wear items like the output sprocket. This BikeMaster 14-tooth countershaft gear is built to integrate seamlessly with 428 chain setups on compatible platforms. Proper meshing between the chain links and the gear teeth prevents slippage and maintains efficient kinetic energy transfer from the engine to the rear axle under all operating loads.
Forged from tough carbon steel, this unit handles heavy throttle application without deforming or rounding off the edges. Each tooth undergoes careful hobbing to ensure smooth engagement and disengagement during shifting cycles. Choosing a quality replacement part safeguards your transmission output shaft from premature damage caused by fatigued drive components.
