RK XSO2:

This is an improved version of O-ring chains. The special shape of the X-rings seals the chain at four sealing points, preventing the lubricant from escaping.

Additionally, the X-ring serves as an extra lubricant reservoir. The lifespan of the chain is extended by about 30%.

The development of the successor to the proven 520XSO is also based on RK's long-standing

experience in MotoGP and meets the highest demands through the use of patented X-rings.
