#428 RK Chain

RK racing chains have been the overwhelming choice of World Championship Teams for the past two decades! They have benefited from their long-term OEM relationships with the major Japanese motorcycle manufacturers; RK has supplied original chains and chains for racing. All high-quality RK chains are made in Japan except the standard RKM series, which are from Malaysia. All RK chains feature quad-staked pin riveting, solid rollers and solid bushings, except the RKM and standard series, which have two-point riveting and curled bushings. They're all pre-stressed and pre-stretched for better performance with fewer adjustments. They feature heavier side plates for more strength and resistance to stretch. MXZ racing chains are made for the serious Kart racer with all components heat treated for high-performance durability; chromoly steel construction with seamless rollers and bushings, and oversized alloy pins for added strength.
