Ideal for off-road motorcycles such as the BETA RR 430 4T (2021–2022), this kit is intended for riders who want a complete transmission ready to tackle mud, jumps, and technical trails. The aluminum sprocket lightens the overall setup without altering the mechanical compatibility of the final drive, while the 520SRX2 chain offers a construction suited to the demands of the terrain.
Before installation, check the pitch and number of links compatibility with your model and adjust the tensioning if necessary. This product is intended for motocross/off-road use — remember to perform regular maintenance (cleaning, tensioning, and lubrication) to optimize the lifespan of your chain.
