Features
RFX Pro Series Elite Aluminum Sprocket - 520 (manufacturer part number: FXRS 50-47 99OR): a sprocket crafted for riders and racers seeking a reliable and lightweight component. CNC machined from 7075 aluminum and anodized in orange, it combines meticulous finishing with a design tailored for the muddy environments of off-road riding.
- Material: CNC machined 7075 aluminum.
- Number of teeth: 47 teeth — chain pitch 520.
- Drainage grooves: clearances for mud to minimize chain/sprocket fouling.
- Design: CAD profile for weight reduction, rigid design for better torsional resistance.
- Finish: orange anodization, laser-engraved RFX logo; color-coded by brand, also available in silver.
- Precision: tight tolerances for better chain/sprocket fit.
Designed for Quad, Cross, and Roadster environments, this standard sprocket adapts to demanding drives while facilitating maintenance on track or in wet terrain. Compatible with recent models such as TRIUMPH TF 450‑X (2026), DUCATI DESMO 450 MX (2026), and STARK FUTURE VARG EX (2026). Replace your sprocket with a robust and lightweight piece designed to last while maintaining a race bike look.
