The JT Chains 520 HDR Competition Chain is a high-strength, non-sealed steel drive chain built for efficient power transfer in motocross and off-road riding. Designed with advanced materials for durability and consistent performance.
The JT Chains 520 HDR Competition Chain is engineered for riders who want reliable drive performance under hard motocross and off-road use. Built from high-grade steel alloys and produced with leading-edge manufacturing, it delivers strong, consistent power transfer while maintaining excellent durability for race practice and everyday riding.
If your current chain is stretched, worn, or causing inconsistent throttle response, replacing it with a purpose-built competition chain helps restore smooth acceleration, better drivetrain efficiency, and predictable feel on the bike—especially under heavy load and frequent shifting.
