Features

RFX Pro Series Elite Aluminum Sprocket - 520 (manufacturer part number: FXRS 31-49 99BK): a sprocket designed for demanding riders in motocross and roadster applications. CNC machined from high-strength 7075 aluminum, it combines lightness and rigidity to withstand the challenges of muddy outings as well as road runs.

Material: CNC machined 7075 aluminum, anodized black.
Number of teeth: 49 teeth, 520 chain pitch.
Design: CAD-optimized profile to lighten the part without compromising rigidity.
Drainage: mud drainage grooves to limit accumulation and preserve the lifespan of the chain and sprocket.
Finish: laser-etched RFX logo, color code by model, and available in silver finish.
Precision: tight tolerances for smoother transmission and better response from the drivetrain.

Designed for both off-road environments and road use, this standard 520 sprocket fits the transmission settings of motocross and roadster motorcycles. Ideal for replacing an original part or fine-tuning the transmission behavior.

Compatible motorcycles (examples):

YAMAHA YZ 450 F (2026)
FANTIC XX 125 (2022)
HONDA FX 650 VIGOR (RD09) (2000)
