This aftermarket Delrin motor gear is intended for Kyosho Mini Inferno owners who need a direct motor pinion replacement. Supplied as a single 13T unit, it fits the motor pinion location on Mini Inferno electric RC vehicles and is sold as an accessory for hobby maintenance.
Delrin lowers friction between mating gears and typically runs quieter than harder plastics, which helps when checking setups and during break-in runs. During installation check the gear mesh and shaft alignment, confirm free rotation by hand, and ensure the motor turns smoothly before powering the model for a full run.
Use this part for routine upkeep and simple tuning swaps where replacing a worn stock pinion with a like-for-like Delrin 13T restores quieter operation and predictable gear engagement on Mini Inferno drivetrains.
