Kyosho Motor Cycle Aluminium Gear Box for drivetrain tuning - KM012N by GPM  [KM012N]

Aluminium gearbox for Kyosho motorcycles

This aluminium gearbox is an RC-scale replacement hop-up designed for Kyosho motorcycle platforms where modified gear ratios are used. The unit focuses on providing a rigid, low-profile housing for spur and pinion engagement while keeping weight low to assist balance and handling when tuning acceleration versus top speed.

The housing installs into standard Kyosho motorcycle engine bays and preserves existing mounting interfaces, allowing common tuning changes without altering surrounding mounts. Aluminium construction improves heat dispersion compared with plastic housings and reduces deformation under higher-torque motors or tighter gearing. Installation calls for basic disassembly of the original gearbox area, verification of pinion and spur alignment, and fine adjustment of mesh using shims or thin plates.

Use this aluminium gearbox when changing gear ratios to maintain alignment and reduce flex; check gear mesh carefully during installation and re-torque mounting fasteners after a run to ensure consistent performance.
