The RFX Pro Series Elite sprocket made from 7075 aluminum (manufacturer part number: FXRS50-5399SV) is designed for demanding riders who want a lightweight and refined final drive. CNC machined and anodized in silver, it features a CAD-designed profile, tight tolerances, and a laser-engraved RFX logo. The mud evacuation grooves promote chain maintenance and contribute to the longevity of the drivetrain, without compromising the rigidity needed for road or off-road demands.
Designed for the world of quads, motocross, and roadsters, this sprocket is mounted as a standard replacement to adjust the gear ratio and manage torque constraints. It is suitable for recent models listed as examples: TRIUMPH TF 450-X (2026), DUCATI DESMO 450 MX (2026), and STARK FUTURE VARG EX (2026).
