JT Chains 520 HDS Ultimate Competition Chain is built for riders who want reliable power transfer and durability in demanding riding conditions. Using leading-edge technology and high-grade special steel alloys, JT Chains produces competition-ready chains engineered to meet or exceed the requirements of modern motorcycles—especially in MX, enduro and off-road riding.
If your current chain is stretching quickly, feeling inconsistent under load, or you simply want a race-focused setup, this non-sealed 520 HDS chain is designed to deliver strong performance with reduced rotating weight and direct feel. The clip-type master link also makes installation and servicing quicker at the track or in the workshop.
