Aluminium gearbox for Kyosho motorcycles

This aluminium gearbox is an RC-scale aftermarket hop-up created for Kyosho motorcycle platforms where altered gear ratios are fitted. It provides a rigid, compact housing to support spur and pinion engagement while keeping mass low to aid handling and balance when tuning for acceleration or top speed.

Designed to fit into conventional Kyosho motorcycle engine bays, the housing retains standard mounting interfaces so common tuning changes are possible without modifying surrounding fixtures. The aluminium construction enhances heat dispersion versus plastic housings and reduces deformation under higher-torque motors or heavy gearing. Installation involves basic disassembly of the original gearbox area, careful alignment of pinion and spur, and mesh verification with shims or fine plates.

Use this aluminium gearbox when altering gear ratios to maintain correct alignment and reduce flex; verify gear mesh during installation and re-torque mounting fasteners after running to ensure reliable performance.
