PBR Steel C45 Standard Sprocket 478 - 520
Manufacturer part number: 478 43 C45
Replacement PBR sprocket made of C45 steel, designed for chain drives with a pitch of 520. Engineered for standard mounting on the gearbox output and swingarm, this 43-tooth sprocket provides a robust solution for OEM replacement on quads and roadsters.
This sprocket installs easily in place of the worn part to restore proper chain guidance and reliable transmission. It is particularly suitable for quads and roadsters such as the following models: CF MOTO 700 CL-X SPORT (2025), KAWASAKI Z 650 RS (2025), and POLARIS TRAIL BOSS 325 (2003) — always check for exact compatibility with your model before installation.
An essential wear part, the PBR steel C45 sprocket helps maintain the correct torque transmitted to the rear wheel and ensures a smooth chain trajectory. Installation is recommended with chain tension checks and inspection of sprockets and axles.
