525XRE XW-Ring Drive Chain

The RK 525XRE chain serves as a high-performance evolution of the XSO range, delivering a 20% improvement in wear life through advanced metallurgy and seal technology. The integrated XW-Ring seals create dual lubrication pools, effectively blocking dirt and debris from the inner rollers and bushings while resisting heat buildup at high speeds. This design balances high tensile strength with lightweight construction to meet the demands of both street and track riding. With a maximum capacity of 1000cc and rated for engines up to 200 HP, this chain is engineered for demanding applications including road, touring, and off-road use. It arrives as an open chain and includes a rivet-type master link for secure installation. Proper installation requires professional tools; specifically, a rivet-style chain closing tool is required to ensure the master link is correctly seated. Note that this product is not certified as street legal for highway use in all jurisdictions unless specifically marked as homologated. Users are advised to verify chain size and link count against original equipment specifications prior to installation, as applications vary.
