Kyosho Motorcycle Alloy Gearbox KM012A Large Tooth Upgrade by GPM  [KM012A]

Replacement aluminium gearbox KM012A for Kyosho motorcycles

The KM012A gearbox is an aluminium alloy aftermarket housing sold as a 1pc kit that includes the mounting screws. Its big-teeth gear layout is intended to change engagement behaviour and provide a stiffer alternative to common plastic housings.

Manufactured from aluminium alloy, the housing alters mesh characteristics through a larger tooth profile, which can improve drivetrain feel and reduce flex for hobbyists focusing on chassis tuning and reliable power transfer.

Fitting is straightforward for competent model builders: remove the factory gearbox, align the alloy housing for correct mesh, and fasten using the supplied screws. Verify gear alignment and free play by hand before powering up the model.

The KM012A is ideal for builders seeking a metal gearbox option to enhance drivetrain stability; always double-check fit against your Kyosho motorcycle before installation.
