Kyosho Motorcycle Aluminium Gear Housing KM012A (Large Teeth) by GPM  [KM012A]

KM012A alloy gearbox housing for Kyosho bikes

This one-piece KM012A gearbox is an aluminium alloy replacement supplied with screws for mounting. The design uses a big-teeth gear profile to alter mesh dynamics and offer a metal alternative to common plastic housings.

The alloy housing increases rigidity and changes gear engagement compared to smaller-tooth spurs, which can be useful when tuning the drivetrain on hobby-scale electric motorcycles. It is intended for riders prioritising drivetrain consistency and reduced flex.

Installation is straightforward for experienced builders: remove the original unit, orient the alloy housing for correct mesh, and secure with the supplied fasteners. Always check alignment and clearances by hand-rotating the drivetrain before running the model.

The KM012A offers a robust aluminium option for tuning and durability improvements; confirm compatibility with your Kyosho chassis prior to fitment.
