RK 525XRE and 530XRE are designed with the concept of “From the Circuit to the Street." Not only suitable for general street riding but also for racing performance. High durability and lightweight. Developed with FIM Endurance World Championship (EWC) champion teams.
RK XRE chains feature RK`s only technology of XW-Ring, which has two lubrication pools, three contact lips, and a triple barrier structure to seal the lubrication further and prevent debris from entering the chain. The durability has been dramatically improved from the XSO series.
