The RFX Pro Series Elite aluminum 7075 sprocket is designed for off-road riders seeking lightweight, precise equipment suitable for muddy conditions. CNC machined and anodized black, it features 51 teeth with a 520 pitch and a CAD-optimized profile to reduce rotating mass without sacrificing rigidity.
Designed for motocross and demanding terrains, this sprocket replaces the original component while reducing inertia and facilitating maintenance thanks to the drainage grooves. Check the 520 pitch and the number of teeth for compatibility with your pinion and chain before installation. Examples of applications: KAWASAKI KX 450 X (2026), KX 250 X (2026), and KX 250 (2026).
