Starter Double Gear – For Quad SPY Racing SPY350

Starter Double Gear – For Quad SPY Racing SPY350

Gear for the Starter Reduction Gearbox (Zongshen 350cc)

This Starter Double Gear is a critical component of the reduction gear mechanism that transfers the rotational movement from the starter motor to the flywheel of your Quad SPY Racing SPY350.

The double gear serves to reduce the high rotation speed of the starter motor to the necessary lower speed to crank the engine. Wear or damage to this gear is a common cause for loud noises during startup or the starter failing to engage. It is suitable for the SPY350 models that use the corresponding Zongshen 350cc engine.
