RFX Pro Series Elite Aluminium Sprocket - 520 (Manufacturer part number: FXRS 20-47 99GN): a sprocket designed for motocross, combining lightness and robustness. CNC machined from 7075 aluminum, it is aimed at demanding riders who need a reliable part to control their machine's transmission in muddy conditions.
- Material: CNC machined 7075 aluminum for a good balance of weight and strength.
- Number of teeth: 47 teeth, CAD-optimized profile to reduce unnecessary mass.
- Chain pitch: 520 — compatible with drivetrains designed for this pitch.
- Mud-resistant design: drainage grooves to limit clogging and extend the lifespan of the chain and sprocket.
- Finish: green anodization, laser-engraved RFX logo, and color coding according to the motorcycle brand.
- Precision: tight tolerances and rigid design increasing resistance to twisting.
Designed for the terrain, this green RFX sprocket fits recent trail and motocross models — including Kawasaki KX 450 X, KX 250 X, and KX 250 (2026 models) — and easily integrates into 520 configurations. A high-performance replacement part with a racing look, it provides strength and consistent engagement without compromising on weight.
