RFX Pro Series Elite Aluminum Sprocket - 520 (Ref. FXRS 50-50 99BK)
This RFX Pro Series Elite sprocket is CNC machined from 7075 aluminum to provide an optimized stiffness-to-weight ratio. Designed for 520 chains, it features 50 teeth and a black anodized finish that withstands the rigors of the terrain. The mud evacuation grooves limit debris buildup between the links and the teeth, extending the lifespan of both the chain and the sprocket.
Suitable for Quad, Cross, and Roadster uses, this sprocket is aimed at riders looking for a robust chain component for the track or road. Common applications include: TRIUMPH TF 450-X (2026), DUCATI DESMO 450 MX (2026), and STARK FUTURE VARG EX (2026). For secure installation, ensure to adhere to the 520 pitch and the number of teeth, and regularly check for wear on the chain and sprocket.
