DescriptionRFX Pro Series Armalite Double Compound (Steel/Aluminium) - 520 Sprocket
RFX Pro Series Armalite Aluminum Sprocket - 520 (Manufacturer Part No: FXRS 50-48 ALRD)
Designed for demanding riders, the RFX Pro Series Armalite composite sprocket combines a CNC machined 7075-T6 aluminum center with a high carbon steel (HCS) outer ring. The "double ring" construction offers a good balance between lightweight and durability of the teeth, while minimizing stress on the rivets thanks to the Hex-Drive interface between the two parts.
- Color: Anodized Red
- Material: 7075 CNC Aluminum Center / HCS Outer Ring
- Number of Teeth: 48
- Chain Pitch: 520
- Type: Standard, CAD-optimized profile for lightweight
- Anti-mud release grooves and rigid design for better torsional resistance
Suitable for Quad, Cross, and Roadster environments, this sprocket is intended for machines equipped with a 520 pitch transmission — for example, on modern 450s like the TRIUMPH TF 450-X (2026), DUCATI DESMO 450 MX (2026), or STARK FUTURE VARG EX (2026).
Installation advice: strictly follow the manufacturer's procedure and tighten to the recommended torque. Clean the hub, bolts, and seals, apply suitable Loctite, and tighten evenly while holding the Hex-Drive for perfect alignment and reliable retention on the chain.
