RFX Pro Series Elite Sprocket - 520 (Manufacturer Ref: FXRS 31-50 99BU)
Designed for motocross enthusiasts and demanding roadsters, this RFX Pro Series Elite sprocket is CNC machined from high-strength 7075 aluminum. Its CAD profile and increased rigidity limit torsion while maintaining a lightweight design — an ideal choice for those seeking reliability and a refined finish in their drivetrain.
The sprocket is color-coded by brand and available in silver to match the aesthetics of your machine. The machining tolerances are tight to ensure precise chain engagement and controlled wear. Ideal for both off-road use and street riding, it is particularly suitable for commonly listed models (e.g., YAMAHA YZ 450 F, FANTIC XX 125, HONDA FX 650 VIGOR), subject to verification of fitment on your machine.
A technical and visual choice to replace your original sprocket while maintaining mechanical performance and a polished look on the rear wheel.
