This 14-tooth motor pinion is built for the Kyosho Mini Inferno series and is supplied as one aluminium alloy gear. It is intended as a direct replacement for worn pinions and as a simple upgrade for experimenting with gear ratios alongside your chosen spur and motor.
How it affects setup: swapping to a 14T pinion shifts the motor load and final drive, giving predictable effects on acceleration and top speed depending on spur pairing. It is useful when testing alternative ratios or restoring original gearing after modifications.
Installation guidance: mount the pinion on the motor shaft with correct axial alignment and establish the proper mesh with the spur to avoid early wear. Run the gearbox slowly after installation to check for smooth rotation and to ensure there is no contact with surrounding parts. This item is for model use only.
