This single 1 pcs replacement motor gear is intended for the Kyosho Mini Inferno platform and is a 12T motor pinion manufactured in titanium. The part is supplied as one unit and functions as a direct spare where a 12-tooth motor gear is required.
Use the pinion to replace a worn item or when validating small changes to the final drive ratio during tuning. Titanium is specified as the material; installers should verify shaft diameter and correct gear mesh before powered operation to avoid accelerated wear to adjacent components.
Fitting procedure: install the pinion on the motor shaft maintaining the original orientation, confirm axial alignment with the spur gear, and secure any set screw or retention device used by your motor. Manually rotate the drivetrain after installation to confirm smooth engagement and correct mesh ahead of powered testing.
