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

Delrin motor pinion for Mini Inferno

This aftermarket pinion is made for the Kyosho Mini Inferno platform and supplied by GPM as DMIF012T. The part is a 12-tooth Delrin motor gear intended for RC-scale electric drivetrains, serving as the motor pinion that meshes with the spur to form the final drive ratio.

Delrin (acetal) offers low friction and quiet engagement compared with some metal options, making it useful when you want smoother gear mesh and reduced drivetrain buzz. A 12T pinion reduces gear ratio compared with larger tooth counts, which affects acceleration and top-end balance; use it when tuning for quicker throttle response on short tracks.

Installation is straightforward for standard Mini Inferno motor mounts: remove the motor, swap the pinion on the motor shaft, set correct mesh with the spur, and secure the set screw. Verify rotation and clearance before full-power testing to avoid premature wear on the pinion or spur.
