BMW S1000RR Rear Sprocket - Renthal - 520-41P Teeth - Hard Anodized (2019–2023). A precision CNC-machined rear sprocket built for riders who want responsive acceleration and dependable performance.

Renthal's UltraLight rear chainwheel is machined from 7075-T6 aluminum to tight tolerances and hard anodized for durability. The 520 pitch, 41-tooth layout trims rotating mass for quicker spin-up—up to 66% lighter than steel—while maintaining strength. Computer-engineered tooth profile and verified concentricity aid efficient power transfer and consistent chain engagement. Self-cleaning grooves between every tooth help shed debris and reduce buildup on spirited street or track days.
