This listing is for a single 1 pcs 12T motor pinion in titanium designed for the Kyosho Mini Inferno platform. It is supplied as one unit and intended as a direct replacement where a 12-tooth motor gear is required.
Fit this pinion when swapping out a worn gear or when testing minor changes to the final drive ratio while tuning. Titanium is noted as the construction material; installers should check shaft fit and gear mesh before full operation to prevent accelerated wear on nearby components.
Installation advice: slide the pinion on in the same orientation as the removed part, check axial alignment against the spur gear, and confirm any retention screw or clamp is tightened. Turn the drivetrain by hand after installation to confirm smooth engagement and correct mesh prior to powered runs.
