RFX Pro Series Elite Aluminum Sprocket - 415
Manufacturer reference: FXRS 57-40 99BU
Designed for off-road use, this RFX Pro Series Elite sprocket combines lightweight and durability. CNC machined from 7075 aluminum, it features an optimized CAD profile and a blue anodization that protects the part while providing a racing look. The mud evacuation grooves facilitate self-cleaning of the teeth on muddy trails, preserving the lifespan of the chain and sprocket.
Ideal for small displacement motocross bikes, it follows standard dimensions in 415 and offers a neat finish with the RFX logo laser-engraved.
