Kyosho Mini Inferno 12T Delrin Motor Gear DMIF012T by GPM  [DMIF012T]

12T Delrin motor gear for Mini Inferno

This 12-tooth Delrin motor gear is an aftermarket unit intended for Kyosho Mini Inferno cars and supplied in the DMIF012T fitment. The pinion is designed to mesh with the spur gear and set the effective final drive on typical 1/10 scale electric setups.

Manufactured in Delrin (acetal), the gear gives low friction and quieter engagement compared with metal alternatives, which helps reduce drivetrain noise and harshness. Choosing a 12T pinion lowers gearing relative to larger pinions, boosting initial acceleration and improving throttle response for shorter courses.

Fitment is simple on standard motor mounts: remove the motor, slide the pinion onto the shaft, adjust mesh with the spur, and tighten the set screw. Confirm correct rotation and clearances, then perform a low-power bench test before track use to prevent premature damage to the pinion or the spur.
