JT/PBR 520HDS 13/51 chain kit designed for off-road pistons: robust transmission and optimized components for motocross practice. This kit combines the super-reinforced HDS chain with XS-Ring seals and an ultra-light aluminum sprocket for a lightweight assembly without sacrificing longevity. Black/steel finishes provide a sleek look on the sprocket and the crown.
Ideal for motocross riders looking for a high-performance and lightweight transmission. The aluminum crown reduces unsprung mass for improved rear-end responsiveness, while the HDS chain with XS-Ring seals limits wear and dirt penetration. For optimal lifespan, check tension, lubricate regularly, and adhere to the manufacturer's torque specifications during installation.
