RFX Pro Series HCS Steel Sprocket - 520 (Manufacturer Ref: FXRS 31-50 99ST)
Designed for riders seeking a robust and reliable sprocket without frills, the RFX Pro Series high carbon steel sprocket combines toughness and precise machining. Its CAD design and CNC laser cutting ensure a consistent tooth profile and tight tolerances, while the optimized design helps reduce excess weight compared to more massive full steel models. Ideal for use on motocross or roadster machines, it adheres to the 520 standards with 50 teeth for a transmission that meets original specifications.
Supplied in a silver finish, this standard model installs on the hub according to manufacturer recommendations. Follow the manufacturer's torque specifications and apply an appropriate thread-locking compound (blue Loctite) on the bolts. Check the alignment and chain tension after installation.
