Features
RFX Pro Series HCS Steel Sprocket - 520 (54 Teeth) — designed for riders and racers who demand strength and longevity without breaking the bank. Made from high-carbon certified steel, this sprocket offers excellent wear resistance while maintaining a lightweight profile thanks to CAD design. Laser-cut for optimal precision, it ensures tight tolerances and a reliable fit on the hub.
- Material: HCS steel (high carbon steel) — silver color
- Number of teeth: 54
- Chain pitch: 520 (standard)
- CNC laser cut for precise finish
- CAD-optimized profile to limit excess weight compared to aluminum
- Mud evacuation grooves and rigid design enhancing torsional resistance
- Type: standard — reduced tolerances for better transmission performance
Recommended installation: place the motorcycle on a stand, remove the rear wheel and chain, then install the new sprocket ensuring the hub is clean. Clean bolts and nuts, apply blue Loctite, tighten evenly, and follow the manufacturer's recommended torque specifications. Finally, check the alignment and tension of the chain.
Universe: Quad / Cross / Roadster. Manufacturer reference: FXRS 50-54 99ST. A robust and precise sprocket to keep your transmission ready for off-road sessions or daily road use.
