This 2pc alloy wheel gear assembly is made for Kyosho motorcycle models using the KM155-19T36T and KM153-11T37T gear profiles and fits the KM012A gearbox arrangement. The parts are supplied as matched wheel gears intended for routine drivetrain repair or incremental tuning where worn gears need replacing or different tooth counts are tested.
Compatibility depends on the gear codes: the kit includes KM155-19T36T and KM153-11T37T wheel gears and is designed to interface with the KM012A gearbox layout. When installing, check gear mesh and axial alignment inside the gearbox and confirm seals and bearings remain correctly seated to protect gear life and drivetrain efficiency.
As a replacement or hop-up component, this assembly restores correct tooth engagement and maintains torque transfer through the gearbox to the wheel, while allowing straightforward swaps when experimenting with tooth-count changes. The pair is supplied for symmetrical wheel installations.
Use this alloy gear assembly when repairing or fine-tuning the drivetrain of compatible Kyosho motorcycle kits, and always verify mesh and bearing seating during installation for reliable operation.
