Kyosho GPW19 is a precision machined aluminum gear housing made for Hanging On Racer models. This replacement both sharpens the look of your bike and helps keep motor temps lower during longer sessions.
Aluminum's thermal properties let heat move away from the motor faster than stock plastic parts. Swapping in the Kyosho GPW19 helps reduce run temperatures and supports more consistent motor performance.
Engineered for a direct fit on Hanging On Racer units, the housing aligns precisely with mounting points to reduce play and vibration. High tolerance machining keeps gear alignment accurate for reliable use.
