Features
RFX Pro Series Elite Aluminum Sprocket - 520 (Manufacturer Part No: FXRS 50-49 99BU)
Designed for demanding transmissions, this RFX Pro Series Elite sprocket is CNC machined from 7075 aluminum for an excellent balance of lightweight and rigidity. Its CAD profile and tight tolerances aim for precise interaction with the 520 chain, while the drainage grooves limit the accumulation of mud and gravel on the teeth — a significant advantage on motocross or off-road terrains.
- Material: 7075 aluminum, CNC machining.
- Color: Anodized blue (RFX color code).
- Number of Teeth: 49 teeth (ref. 49).
- Chain Pitch: 520.
- Finish: Laser-etched RFX logo, durable anodization.
- Design: CAD profile to lighten without sacrificing rigidity; drainage grooves to limit clogging.
Suitable for Quad, Cross, and Roadster environments, this sprocket is aimed at riders and enthusiasts looking for a reliable and lightweight drive component for their transmission. Highly sought after for recent machines (e.g., Triumph TF 450-X 2026, Ducati Desmo 450 MX 2026, Stark Future Varg EX 2026), it mounts as a standard replacement on compatible 520 models.
