Description

Chain and sprocket wear is inevitable—but premature failure doesn't have to be. This RK OEM Replacement Kit restores your S 1000 RR's drivetrain to factory specifications with premium case-hardened components engineered to handle high-mileage performance demands. Whether you're replacing worn stock gearing or performing preventive maintenance, this kit delivers the durability and precision your superbike deserves.

Designed specifically for the 2009–2011 BMW S 1000 RR, the kit pairs a C45 steel rear sprocket with a case-hardened and quenched front sprocket, maintaining OEM gearing ratios for seamless compatibility and predictable power delivery across the rev range. Installation is straightforward for riders with basic mechanical skills, though professional fitment is always recommended for optimal chain tension and alignment.
