BMW S1000RR Rear Sprocket — Renthal UltraLight 520-43P, Hard Anodized (2019-2023). A precision 43-tooth upgrade that cuts weight and delivers reliable drive.
Renthal CNC-machines this rear chainwheel from 7075-T6 aluminum to tight tolerances for accurate fitment, concentricity, and load control. Hard anodizing boosts surface durability, while refined tooth profiling aids efficient power transfer. Self-cleaning grooves limit debris buildup, and the all-aluminum design is 66% lighter than steel to help reduce rotating and unsprung mass.
