DescriptionRFX Pro Series Armalite Double Compound (Steel/Aluminium) - 520 Sprocket
Product details :
Features
The RFX Pro Series Armalite sprocket (manufacturer reference FXRS 50-50 ALOR) combines lightness and robustness for demanding riders. Designed for competition and road use, it features a double-ring construction: a center machined from 7075-T6 aluminum to reduce unsprung mass and a high-density HCS steel outer ring to protect the teeth from wear. Anodized orange finish for a racing touch and increased resistance to the elements.
- Type: RFX Pro Series Armalite double composite sprocket
- Material: CNC 7075 aluminum center / HCS outer ring
- Number of teeth: 50 (520 pitch)
- Interface: Hex-Drive between rings for better power transmission
- Design: Lightweight CAD profile, mud evacuation grooves, and enhanced rigidity
- Color: Anodized orange
Universal compatibility: quad, motocross, and roadster. Supplied with detailed installation instructions — be sure to follow the manufacturer's recommendations for tightening, chain alignment, and the use of Loctite if indicated. Intended for riders who want to reduce rear wheel inertia without sacrificing tooth longevity.
Frequently fitted motorcycles: Triumph TF 450-X (2026), Ducati Desmo 450 MX (2026), Stark Future Varg EX (2026).
