KM012A aluminium gearbox upgrade for Kyosho motorcycle RCs

The KM012A is an aftermarket aluminium gearbox housing supplied as a single-piece set including mounting screws. Its large-tooth gear arrangement offers altered engagement characteristics and a firmer drivetrain response than many plastic housings.

Built from aluminium alloy, this housing changes gear mesh behavior and increases stiffness under load, which riders often use as part of drivetrain tuning on hobby-scale electric motorcycles where reliability and a firm feel matter.

Installation is aimed at experienced model technicians: remove the original gearbox, position the alloy housing for the correct mesh depth, then secure using the supplied screws. Rotate the drivetrain by hand to confirm smooth operation before powering the model.

Specifications

  • Item: Kyosho Motor Cycle Alloy Gear Box With Screws
  • Material: Aluminum alloy
  • Model Number: GPM KM012A
  • Compatibility: Designed for Kyosho motorcycle RC models

As an aluminium alternative, the KM012A is intended for builders seeking improved drivetrain stiffness; always verify fitment on your specific Kyosho model prior to installation.

Do I need extra parts to fit this?

No additional parts are generally required; the supplied screws allow direct installation provided your chassis matches the mount points.

Will it change gear noise?

The larger tooth profile may alter the acoustic signature of the drivetrain, producing a firmer engagement sound compared with smaller-tooth spurs.

How should I set gear mesh?

Set a small, even clearance consistent with the larger tooth profile, tighten screws evenly, and check for binding across the full rotation range.

Is this suitable for competition use?

It provides a stiffer housing which can benefit tuned setups, but always confirm compatibility and perform break-in runs to ensure reliability under competitive conditions.
