Replacement motor pinion kit for Kyosho bikes

This aftermarket motor pinion gear kit suits Kyosho Motorcycle installations. It contains three steel #45 pinions in 11T, 12T and 13T, delivered as a 3pcs pack to support simple tuning changes and to replace worn motor pinions on scale motorcycle models.

Use the different tooth counts to adjust the effective final drive: lower tooth counts favour top speed while higher counts favour acceleration. Steel #45 provides a practical compromise of toughness and ease of manufacture for small motor pinions.

Installation notes: remove the existing pinion retention, install the chosen pinion, set proper mesh with the spur or gearbox input and verify smooth rotation before use. Re-check mesh after a brief break-in run.

The set contains three motor pinions: 11T, 12T and 13T, supplied together as a 3pcs kit.
Steel #45 is suitable for routine motor-side use, but check for signs of wear and maintain correct mesh to maximise life.
Measure your motor shaft and review the retention method; these pinions fit where shaft diameter and mounting match the pinion bore and fixing style.
