JT/PBR 520HDS 13/51 Standard Chain Kit - Ultra-Light Sprocket by JT DRIVE CHAIN: a complete kit designed for motocross, which includes a chain, a 13-tooth sprocket, and a 51-tooth sprocket. Designed for off-road motorcycles, it combines lightweight materials and reinforced components for reliable transmission on muddy tracks and rough terrains.

The aluminum sprocket reduces unsprung mass compared to a steel sprocket, while maintaining suitable strength for off-road demands. The super-reinforced HDS chain and XS-Ring seals limit dirt intrusion and help maintain lubrication over time — important advantages for those who tackle jumps and accelerations in motocross.
