Precision #45 steel 12T pinion for scale motorcycle motors

This 12T pinion is supplied as 1 pc and is fabricated from #45 steel to provide a robust replacement for Kyosho-compatible motorcycle motor shafts. The geometry matches standard 12T profiles used across many model motorcycle motors.

Installation requires mounting the pinion on the motor shaft, establishing correct tooth engagement with the spur or gearbox input, and securing the set screw. Verify shaft diameter and set screw alignment prior to final tightening to ensure proper mesh and reduce risk of slippage.

From an upgrade perspective, a #45 steel 12T pinion delivers consistent contact geometry and improved wear resistance relative to softer alternatives, making it suitable where durability and predictable gear behaviour are priorities for scale motorcycle motor builds.

What is provided in the package?

One 12T #45 steel pinion supplied as the replacement gear for motor shaft mounting.

What should I check before fitting?

Confirm motor shaft diameter and the set screw position, and inspect the spur gear for wear to ensure correct final gear mesh.

How does material affect performance?

Steel #45 offers improved wear resistance and stable mesh characteristics versus softer materials, which helps maintain consistent performance across run sessions.
