PBR C45 Steel Sprocket 4385 - 525 (Manufacturer Ref: 4385 43 C45T)
The PBR sprocket made of C45T steel is a part designed for demanding riders who seek robustness and reliability for transmission. CNC machined and then treated (quenching and tempering by induction) in the tooth area, it is built to withstand the repeated stresses of the chain while maintaining precise tooth geometry. Its black finish gives it a sleek and distinctly motorcycle look.
Born from PBR's developments with competition teams, this sprocket is aimed at roadsters and lightweight off-road machines that require a durable transmission part. It is suitable for models such as Yamaha R9 (2025), Suzuki V-Strom 800 SE (2025), or Husaberg FE 450 IE (2013) — however, please check the exact compatibility with your model and desired gearing before installation.
Replace your sprocket with an original PBR part to restore a clean tooth profile and 525 compatibility, a key element for a well-aligned chain and healthy transmission both on the road and off the beaten path.
