This single 12T aluminium-alloy motor gear serves as a precision replacement pinion for Kyosho Mini Inferno models, aimed at tuners and hobbyists seeking consistent engagement and predictable drive ratio changes on 1/10 electric platforms.
The aluminium-alloy construction noted in the listing prioritises a uniform tooth profile and stable mesh behaviour in typical use. Verify motor shaft dimensions and the pinion retention style before installation to ensure correct seating and to protect the mating spur gear from undue wear.
Recommended procedure: isolate power, remove or access the motor, fit the 12T pinion to the motor shaft, set minimal non-binding mesh, secure the set screw, and complete a controlled low-speed verification to confirm smooth engagement on the track.
