This 11-tooth steel #45 pinion is supplied as a single 1pc aftermarket replacement for Kyosho motorcycle model motors. It adheres to the 11T and steel #45 specification listed in the product title for hobby drive train repairs.
Installation follows standard practice: remove the motor, remove the old pinion, press or slide the new 11T steel pinion on to the motor shaft, secure with the motor's fixing method, and verify gear mesh with the spur gear before finishing. Check axial placement and fastener security to reduce wear and ensure reliable operation.
In maintenance and tuning, this steel #45 pinion is a robust option when adjusting ratios or replacing worn parts. Regularly inspect teeth and perform bench rotation checks for smooth engagement before use on track or road.
