This aluminium rear wheel shaft, part number KM025R, is supplied as a single-piece axle for Kyosho motorcycle models and is designed for model-level maintenance, repair, and setup adjustments. It installs in the rear wheel assembly to replace worn or bent shafts and restore correct axle seating.
During installation pay attention to straightness, hub bore condition, and bearing fit. Inspect mating surfaces and bearings for wear, ensure the shaft is seated squarely in the hub, and tighten retaining hardware to the model maker's recommended torque values to avoid introducing play.
As an upgrade component, the aluminium shaft can help reduce rear wheel play when bearings and hubs are in good condition. Use matching wheel nuts and correct hardware, and avoid forcing the shaft during installation to preserve alignment and service life.
