Chain RK Japan 520XRE XW-ring +CL (connecting link)

Sealed chain for big and middle CC motorcycles
RK 520XRE is designed with cutting-edge technology from various international on-road and off-road racing, delivering racing performance, high durability, and lightweight construction for quick and smooth acceleration. RK 520XRE can be used both on-road and off-road
RK XRE chains feature RK’s exclusive XW-Ring technology, with two lubrication pools and three contact lips—a triple-barrier structure that further seals in the lubricant and prevents debris from entering the chain. Durability has been dramatically improved compared with the XSO series.
RK 525XRE and 530XRE are designed with the concept of “From the Circuit to the Street,” making them suitable not only for general street riding but also delivering racing performance, high durability, and lightweight construction developed with FIM Endurance World Championship (EWC) champion teams.
