KYOSHO Motorcycle 13T Steel Motor Gear by GPM KM013TS  [KM013TS]

Kyosho motorcycle 13T steel motor gear

This is an RC-scale motor pinion intended as a direct replacement or tuning option for Kyosho motorcycle models that use a 13T motor pinion. The part is manufactured in steel #45 and supplied as 1 pc to replace a worn or damaged motor gear without altering the motor or gearbox housings.

Functionally, a 13-tooth motor pinion is a common choice when adjusting final drive characteristics; fitting a different tooth count changes acceleration and top speed trade-offs. As a steel pinion, this item is focused on wear resistance and consistent tooth engagement compared with softer materials, making it suitable for routine maintenance and tuning sessions.

Installation notes: remove the motor from the chassis per your model's standard procedure, slide the gear onto the motor shaft ensuring correct axial alignment and mesh with the spur gear, and secure it using the original fastening method. After installation, rotate the drivetrain by hand to confirm smooth mesh and no binding before powering on the model.
