Manufacturer Reference: 4585 45 C45T — PBR steel C45T sprocket, designed for 525 transmissions. Designed for roadsters and sport-touring machines, this sprocket combines robustness and precise engagement to support the chain on the road as well as on long journeys.
CNC machined and then subjected to quenching and induction tempering in the tooth area, the PBR C45T sprocket offers a hardened tooth surface to resist wear from chain/sprocket contact. Its black finish gives it a sleek and compact look while protecting the material.
Result: a mechanical part designed for hardness in the critical wear area, enhanced reliability, and an excellent price-quality ratio — assets sought after by demanding motorcyclists. Compatible with many roadsters, it notably fits models such as the BMW S 1000 R / XR (compatibility examples to be verified according to year and configuration).
