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 MXZ4 series chains are made for the serious supercross and motocross racer. MXZ4 chains feature chromoly steel construction with seamless rollers and bushing. RK's Chromized pins drastically improve the wear resistance more than two times compared to normal non-sealed chains while absorbing shock loads from extreme jumps. All components are heat-treated using RK's exclusive HIT (Heat Induction Transfer) process.
