Reinforced Heavy Duty Motocross Chain

RK Special HCR Treatment

The 520KXZ features special alloy pins with RK's Special HCR Treatment - High Tech Chromium Carbide Layered Pins - for better wear resistance. This advanced pin treatment significantly extends chain life under the demanding conditions of motocross racing, where chains are subjected to high loads, impacts, and abrasive dirt and debris.

Premium Sealed Chain Construction

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