Manufacturer Ref: FXRS 50-48 99BK ā RFX Pro Series Elite Aluminum Sprocket - 520 by RFX. Designed for 520 transmissions, this rear sprocket combines lightness and strength for off-road, quad, and roadster applications.
CNC machined from 7075 aluminum, it features a CAD-designed profile and a durable black anodized finish. Mud evacuation grooves facilitate self-cleaning between the links and limit premature wear of the chain and sprocket. The RFX logo is laser-etched for a refined finish.
The rigid design and controlled manufacturing tolerances contribute to better chain-sprocket engagement and increased resistance to twisting without adding excessive weight. This RFX Pro Series Elite sprocket is available in several colors to match the aesthetics of your machine.
Example compatibilities: TRIUMPH TF 450-X (2026), DUCATI DESMO 450 MX (2026), STARK FUTURE VARG EX (2026). Please check the pitch and number of teeth of your setup before ordering.
