RFX Pro Series Elite Sprocket ā 520 (Manufacturer Part No: FXRS 40-47 99BK)
Designed for motocross riders and roadster enthusiasts seeking lightweight and durability, this RFX Pro Series sprocket is CNC machined from 7075 aluminum. Its CAD profile and tight tolerances ensure a precise and consistent part with every installation, while the mud evacuation grooves extend the lifespan of both the sprocket and the chain in dirty terrains.
The combination of a premium alloy, protective anodization, and precision machining makes this sprocket a serious choice for anyone wanting a lightweight, durable, and easy-to-maintain part after muddy rides. Compatible with 520 pitch chains and available in model-specific color coding, it is particularly suited for machines like the SUZUKI RM-Z 450 (2026), RM-Z 250 (2026), and RMX 450 (2019).
