525ZXW Black Scale Chain & Sprocket Kit

The RK Racing KA-RK-H2 is a premium chain and sprocket kit engineered for high-performance street and track use, specifically designed for the Kawasaki H2 and H2R models. The kit centers around RK's top-tier 525 ZXW Black Scale Chain, renowned for its exceptional durability and performance in extreme conditions. This chain boasts RK’s patented XW-Ring seal, a multi-lip design that creates three lubrication pools to combat high-speed abrasion, heat buildup, and lubricant loss, potentially offering up to ten times longer wear life compared to standard chains. The XW-Ring seals are also compression and distortion resistant, ensuring optimal rotating efficiency. The kit includes a black steel rear sprocket, heat-treated for maximum durability and longevity, and a front sprocket crafted from chromemoly steel for superior strength. Both sprockets are designed with specific teeth counts for the Kawasaki H2/H2R, with the featured kit including an 18-tooth front sprocket and a 44-tooth rear sprocket. The chain plates are finished with an Electro Deposition Black Paint for enhanced rust resistance, while the pin and roller are plated gold. The kit is completed with a rivet-type connecting link. This RK ZXW series chain is considered OEM equipment for many high-performance Japanese and European motorcycles, including models like the Honda CB1000R and CBR1000RR, and Suzuki GSX-R1000. Its design, developed in cooperation with RK's racing department, makes it ideal for both closed-circuit sports applications and everyday riding.
