This product is a YP100 4-stroke engine-specific starter idle gear (starting shaft), an important component of the starting system. This idle gear is installed between the starter motor and the engine flywheel, transmitting the starter motor's torque to rotate the engine crankshaft for engine starting. Manufactured from high-quality steel with precision machining, it features accurate gear teeth and excellent wear resistance. It is an excellent replacement for the scooter's original starting shaft.

Over time, the starter idle gear may experience tooth wear, gear damage, or bearing failure, leading to abnormal noise during starting, difficulty starting, or complete failure to start. Timely replacement of a damaged starter idle gear is critical to ensuring proper engine starting and reliable operation.
