This single-piece alloy gearbox housing is offered for Kyosho scale motorcycle applications as a metal replacement to the stock plastic case. The part is supplied as one housing intended for rebuilding existing transmissions where wear or deformation has occurred.
Intended fitment covers Kyosho motorcycle platforms referenced in the product title; confirm dimensional and mounting compatibility with the gearbox you are replacing. The alloy housing preserves original layouts and mounting points so it can be used as a direct swap when dimensions match.
Installation is performed by removing the original gearbox, transferring internal gears, shafts and fixings into the alloy case, and then reinstalling the completed assembly into the chassis. The alloy housing provides a stiffer mounting surface that can reduce flex and help maintain consistent gear mesh during tuning and heavier duty use.
Use this alloy gearbox when a metal replacement is required to improve mounting stability and support drivetrain tuning on Kyosho scale motorcycle platforms.
