BMW S1000RR Rear Sprocket - Renthal - UltraLight - Hard Anodized (2019-2023). A precision 7075-T6 aluminum rear sprocket designed to cut weight and deliver consistent power transfer on your S1000RR.

Renthal UltraLight sprockets are CNC machined to extremely tight tolerances for accurate fitment, concentricity, and balanced load dispersion. The hard-anodized finish increases surface durability, while self-cleaning grooves between each tooth help shed debris and maintain smooth engagement. At approximately 66% lighter than comparable steel sprockets, it reduces rotating mass, and the refined tooth profiling supports efficient, reliable chain drive performance. Built in Renthal’s in-house facilities and engineered for the 2019-2023 BMW S1000RR, this is a purposeful upgrade for riders seeking quality materials and precise manufacturing.
