Application and fitment

This steel main gear is supplied as an aftermarket spare for Kyosho motorcycle models that use the same gear profile. It is a single replacement part intended to sit in the existing gearbox and operate with standard RC drivetrain hardware.

Steel construction delivers greater wear resistance than typical plastic alternatives, helping to keep gear engagement consistent and extend intervals between part replacement. The SKM155 works well where hobbyists prioritise durability in the gearbox area of scale motorcycles.

Installation is a matter of basic gearbox service: open the case, compare tooth count and bore to the original gear, install the gear on the shaft at the correct axial position, check the pinion mesh, and reassemble while ensuring free rotation. Replace worn bearings or mating gears found during inspection.

Can I use this gear in any Kyosho motorcycle gearbox?

Only if your model shares the same tooth count, bore size and mounting arrangement. Verify those dimensions against the SKM155 before buying.

Does steel require special lubrication?

Use a suitable gear grease or light oil on bearings as normal. Proper lubrication and correct mesh reduce the chance of accelerated wear on softer mating parts.

What should I check during replacement?

Check the pinion alignment, confirm no burrs on the shaft, verify tooth engagement across the mesh, and spin the drivetrain by hand to confirm no binding.
