Kyosho Motorcycle 11T Steel #45 Motor Pinion KM011TS by GPM  [KM011TS]

11T Steel Motor Pinion for Kyosho Bikes

This aftermarket 11T motor pinion is a single 1pc steel #45 replacement intended for Kyosho motorcycle models. The part matches the title specifications with an 11T tooth count in steel #45 and is supplied as one unit for hobby motor drives.

Fitting is straightforward for experienced technicians: remove the motor, take off the old pinion, slide the new 11T steel pinion onto the motor shaft, secure it using your motor's set-screw or press-fit method, and check gear mesh with the spur before finishing. Verify axial position and tighten fastenings to prevent early wear.

For tuning and upkeep, a steel #45 pinion gives better wear resistance than softer materials and is useful when changing gear ratios, testing mesh, or replacing worn parts. Inspect tooth profile regularly and confirm smooth rotation in the gearbox during bench tests before running.
