Description Starter Pinion for SYM / KYMCO 50cc 2T Scooters The starter pinion is the part that allows the starter motor to engage with the engine gear. Over time these wear out, and fail to engage the motor. When this happens it usually manifests as a crunch sound followed by a buzzing electric motor sound, and it can take multiple attempts to get the scooter to start via the electric start. Replacing the pinion is very easy, and immediately fixes the issue! 65/14 teeth, 8mm shaft
