PBR Steel C45 Standard Sprocket 3552 - 520 (manufacturer reference: 3552 39 C45): a final drive sprocket designed for 520 pitch chain systems. With its 39 teeth and black finish, it is aimed at riders looking for a reliable replacement part for roadsters and off-road machines.
PBR relies on extensive experience in competition to develop sprockets and crowns. The brand applies a strict manufacturing process to ensure consistent tooth profiles and controlled wear. In its range, PBR uses high-quality steels and alloys (e.g., some products in 18NCD5) suitable for the repeated stresses of transmission.
This sprocket is suitable for standard replacement: check the condition of the sprocket, chain, and alignment during installation. Ideal for roadster-type machines and off-road outings, it is particularly compatible with 650 cc models such as the BMW G 650 GS, Husqvarna TR 650 Terra, and Aprilia Pegaso 650 depending on the version.
