PBR Steel C45 Sprocket - Ref. 4507 45 C45 (520)
Designed by PBR, this standard sprocket made from C45 steel is aimed at riders looking for a robust and easy-to-install transmission part. Drawing on the brand's competitive experience, it plays a key role in the chain/sprocket transmission to deliver engine torque without surprises.
PBR emphasizes a demanding manufacturing process, a result of its collaborations in competition. These sprockets are designed for use on the road as well as in light off-road conditions, suitable for standard 520 mounts. They replace worn sprockets to restore a tuned transmission and limit chain jerks.
Motorcycles that may use this type of configuration include machines like the GAS GAS SM 700 (2026), the KTM 690 SMC R (2026), or the TRIUMPH TF 250‑X (2026). Before placing an order, check the number of teeth and the chain pitch of your model to ensure compatibility.
