A single 16-tooth precision aluminium motor pinion designed for Kyosho Mini Inferno applications, supplied as one unit. This component is intended as a robust aftermarket replacement where metal pinions are preferred to improve durability and drivetrain consistency.
Machined from an aluminium alloy, the pinion delivers improved resistance to abrasion over injection-moulded plastics while keeping inertia low for small-scale drivetrains. It fits systems that accept a 16T motor gear and mounts on the motor pinion shaft of compatible Mini Inferno chassis.
Technical notes: verify motor shaft diameter and keying, set accurate mesh with the spur gear and confirm axial alignment to avoid uneven wear. The part is supplied as one piece; adjusting tooth count or material type remains a practical method for tuning acceleration versus top speed in compact RC setups.
