RK 420MS Heavy Duty Chain

Since the RK Takasago Company first began production of motorcycle chains as far back as 1953 the name RK has been synonymous with quality. RK Takasago chain has also been researching and developing high-performance sealed-ring chains for use on modern motorcycles for over thirty years.

RK is the trusted supplier for OEM manufacturers such as Honda, Yamaha, Suzuki & Kawasaki. 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's MS series chains are low-cost non-sealed motorcycle chains, featuring 4 side (Quad) rivet staked pins. When pins are quad riveted, they are stronger and more stabilized; which results in increased stress resistance due to high engine loads and makes the transmission of horsepower to the ground more efficiently. As a result of the change to the 4 rivet staked pins, the addition of solid bushings and the application of RK's new specially formulated coating; RK non-sealed chains now show a 40% increase in chain life!

RK non-sealed chains perfect for low displacement motorcycles that did not come from the factory with sealed chains.
