Remark :
Due to limited stock availability, please notice that some Kyosho items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

How do I know when the spur needs replacement?

Look for rounded or chipped teeth and increased backlash. If you notice slipping or noisy operation under load it is time to replace the spur.

Does tooth count affect tuning strategy?

Yes, a 72T spur shifts the balance between top speed and acceleration. Drivers often adjust pinion size and motor timing to work with the chosen spur for ideal lap times.

Are spare parts available for this gear?

Replacement spurs and compatible pinions are commonly available from Kyosho dealers and aftermarket specialists. Verify pitch and bore when ordering spares.
