RFX Pro Series Armalite 520 Sprocket – 51 Teeth (FXRS 50-51 ALRD)
Designed for demanding riders, the RFX Pro Series Armalite composite sprocket combines a machined aluminum core and a steel outer ring to offer a weight/strength compromise suitable for motocross, quads, and roadsters. Its dual-ring construction limits the rotating mass of the rear end while preserving the longevity of the teeth, providing a crisp transmission feel and controlled wear.
Installation: follow the manufacturer's procedure and specified torque settings. Before each ride, check the chain/sprocket alignment and the condition of the seals. Manufacturer reference: FXRS 50-51 ALRD.
