This single 14-tooth motor pinion is CNC-oriented in its design intent for the Kyosho Mini Inferno platform and is supplied as one aluminium alloy gear. It is produced to provide repeatable fitment as a replacement part and to support ratio testing during setup adjustments.
Engineering and tuning notes: the 14T tooth count sets a defined final drive characteristic, altering motor load and wheel torque in predictable increments. Use this pinion for controlled ratio changes when optimising acceleration or top speed for a given track or drive condition.
Installation procedure: mount the gear with correct axial placement on the motor shaft and establish a correct mesh with the spur to avoid premature wear. Verify smooth rotation and absence of lateral play after installation, and monitor operating temperatures during initial runs to confirm correct engagement. This component is intended for scale model use only.
