Japanese Chain Technology Since 1951
RK Takasago Chain has been engineering premium motorcycle drive chains in Japan for over 70 years. What began in 1932 as Takasago Tekko K.K. evolved into one of the world's leading chain manufacturers. Today, RK supplies OEM chains to Honda, Yamaha, Kawasaki, Suzuki, and Triumph—a testament to their uncompromising quality standards.
Race-Proven Performance
RK chains have powered champions across every form of motorcycle racing. Jonathan Rea won six consecutive WorldSBK Championships on RK chains. You'll find RK in MotoGP, World Endurance, AMA Supercross and Motocross, GNCC, MXGP, and British Superbike. When milliseconds matter, teams choose RK.
Motocross & Off-Road Chains
The MXZ5 represents RK's pinnacle of motocross technology. Built with chromoly steel construction and seamless rollers and bushings, it's one of the strongest supercross and motocross chains available. The MXZ4 brings the same professional-grade construction to mini bikes. For sealed off-road performance, the MXU delivers exceptional durability with ultra-thin UW-seals—perfect for bikes with tight case clearance.
Seal Technology
RK pioneered advanced seal designs that extend chain life dramatically. O-ring chains provide reliable sealing for everyday use. RX-ring seals feature two lubrication pools and seal points, delivering 1.5 to 2 times longer wear life than standard O-rings. XW-ring technology provides triple barrier protection with two lubrication pools—the ultimate choice for high-speed, extreme heat applications.
Street & Performance Chains
The GXW series represents RK's top-tier XW-ring technology, providing up to 10 times longer wear life compared to standard chains. Built for high-speed, high-horsepower machines, GXW handles extreme heat and demanding conditions. The ZXW takes it further with the highest tensile strength in the RK lineup—the strongest, longest-lasting chain available. The XSO series offers RX-ring performance with exceptional value, while MAX O and MAX X provide economical sealed options for street and off-road use.
Application Range
RK manufactures chains in 415, 420, 428, 520, 525, and 530 pitches to cover everything from mini bikes to liter-class sportbikes. Multiple color options include gold, natural steel, chrome, black/gold, black/chrome, red, blue, green, yellow, orange, and pink to match your build.
Quality Guarantee
RK sealed chains carry a 20,000-mile warranty for street use and a one-year warranty for off-road applications. All RK sealed and off-road chains are manufactured at their Japanese factory, while standard and heavy-duty chains come from their Malaysian facility.
