This single 12T aluminium-alloy motor gear is a direct replacement pinion for Kyosho Mini Inferno models, intended to restore proper gear engagement or fine-tune final drive ratios on 1/10 electric setups.
Constructed from an aluminium alloy specified in the listing, the pinion is designed to maintain a consistent tooth profile and good mesh stability under normal club and track use. Always confirm your motor shaft style and mounting method before fitting to avoid accelerated wear to the spur or motor gear.
Fitting tips: isolate power, remove the motor or access the set screw, fit the 12T pinion on the shaft, adjust mesh to a small clearance that avoids binding, then secure the set screw and perform a brief low-speed check to verify smooth engagement.
