Manufacturer Ref: FXRS 60-51 99BU — RFX Pro Series Elite aluminum sprocket, designed for demanding off-road and roadster riding. CNC machined 7075 aluminum alloy for an optimal balance between lightness and rigidity, with a model-specific blue anodized finish.
Designed for riders who want reliable transmission on both trails and roads, this 520 sprocket features 51 teeth and an optimized CAD profile to reduce weight without sacrificing strength. Mud evacuation grooves limit accumulation and extend the lifespan of the chain and sprocket, while the RFX logo is laser engraved for a neat finish.
Compatible with many cross and enduro models — examples: SHERCO 300 SEF-R FACTORY (2023), BETA RR 480 4T (2020), GAS GAS EC 250 RACING SIX DAYS (2020). Before installation, check the chain pitch and number of teeth to ensure compatibility with your sprocket and mounts.
