This aftermarket alloy wheel gear assembly is supplied as a 2pcs set for Kyosho motorcycle RC drivetrains, produced under model KM1739T by GPM. The kit maps to the fitments listed in the product title and is engineered for fitting with the GPM KM012A Gear Box.
Manufactured from alloy using precision processes, these gears provide improved wear resistance compared with injection molded plastic and serve as the driven wheel gear element that transmits torque from the motor, through the gearbox, to the wheel. The alloy construction improves contact life and resists deformation under load.
Installation notes for technicians: confirm correct axial seating in the Gear Box, set backlash to the recommended clearance, inspect rotational runout, and secure retaining hardware to factory torque values. Validate smooth engagement by slowly rotating the drivetrain under no-load before full-power testing.
Recommended for technicians replacing worn driven wheel gears or upgrading to CNC-friendly alloy components to improve durability and fitment stability in Kyosho motorcycle geartrains; confirm chassis codes and gearbox compatibility before installation.
