Why Choose RK Chains?

Since RK Takasago first began production of motorcycle chains in 1953, the name RK has been synonymous with quality. With over 30 years of research and development in high-performance sealed-ring chains, RK is the trusted OEM supplier for Honda, Yamaha, Suzuki, and 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, and Rockstar Energy Husqvarna Factory Racing Teams.

Revolutionary XW-Ring Technology

The RK EXW features RK's advanced XW-Ring seals with triple barrier grease protection plus anti-debris technology. Anti-debris protection is vitally important to maximise chain wear life by eliminating debris friction between internal components - critical for ATV and Enduro riding in New Zealand's diverse terrain. The XW-Ring design delivers superior sealing performance compared to standard O-Ring and X-Ring chains, keeping grease in and debris out for dramatically extended service life.

Extreme Performance Engineering

The EXW was designed to handle increased torque stresses and wears 10 times longer when compared to non-sealed chains. Special thermal crack-resistant side plates protect against thermal cracking caused by debris or components impinging the chain's movement - where rapid heating and cooling cycles can cause catastrophic failure in lesser chains. Whether you're racing enduro stages or pushing your ATV hard across New Zealand's backcountry, the EXW is engineered to keep up.

Premium Heat-Treated 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, quieter operation. All RK seals are made from an advanced Nitrile Butadiene composite for maximum performance and wear life.
