Description
Your BMW S 1000 R’s drivetrain works harder than most—and after high-mileage use, your OEM chain and sprockets need replacement to maintain the precision shifting and reliability you demand. This RK kit restores factory gearing geometry and engagement characteristics with premium case-hardened steel components designed to handle the full performance potential of your bike. Rather than mixing and matching parts, a matched kit eliminates guesswork and ensures consistent power delivery from engine to rear wheel.
