This is a single 1 pcs replacement 12T motor pinion in titanium, intended for the Kyosho Mini Inferno platform. The part comes as one piece and is suitable as a direct spare where a 12-tooth motor gear is required.
Use this pinion to replace worn gears or when experimenting with slight drive ratio changes during tuning. The titanium material is listed as the construction; confirm correct shaft diameter and gear mesh before use to avoid premature wear to surrounding components.
Fitting notes: install the pinion in the same orientation as the removed unit, confirm axial alignment with the spur gear, and ensure any set screw or retention method is properly seated. Manually rotate the drivetrain after fitting to verify smooth engagement and correct mesh before powering the model.
