RK chains are used by professional race teams around the world including MotoGP Repsol Honda, WSBK Kawasaki Racing Team, AMA SX/MX Monster Energy Pro Circuit Kawasaki, FMF KTM Factory Racing Teams, Rockstar Energy Husqvarna Factory Racing Teams & many more.

All RK Sealed chains feature heat treated hi-carbon alloy steel components, giving unrivalled wear life. Seamless rollers that allow the chain to run freely between the teeth of the sprocket and reduce chain vibration. All RK seals are made from an advanced Nitrile Butadiene composite for maximum performance and wear life.

RK 520XSO2 is designed for Middle Displacement Motorcycles, a lightened chain weight while securing the strength required, provides an enhanced light feeling of acceleration.
