12T #45 steel motor pinion suitable for Kyosho models

This 12-tooth pinion is supplied as 1 pc and serves as an affordable replacement for Kyosho-style motorcycle motors. Constructed from #45 steel, it conforms to the common 12T profile used across many model motorcycle motors.

Installation requires sliding the pinion onto the motor shaft, aligning the teeth with the spur or gearbox input, then fastening the set screw. Verify shaft diameter and the set screw location to ensure correct mesh and secure fastening.

Using a steel 12T pinion delivers a stable contact pattern and increased resistance to wear over softer pinions, which will impact both low-end response and top speed according to your overall gear ratio. Choose this part when a reliable, standard motor pinion is needed for Kyosho-compatible setups.

Is a set screw included?

The pinion is supplied as the gear only; use your motor's existing set screw or the one from your original pinion.

Will this change my gearing?

The tooth count is 12T; swapping pinions only changes gearing if the replacement tooth count differs from your original.

Maintenance advice?

Inspect the pinion for wear regularly, keep the mesh clean and re-tension the set screw after initial runs.
