RFX Pro Sprocket 13 Teeth (Manufacturer Ref. FXFS 24-13 99BK) — Front sprocket designed for motocross, built to withstand muddy trails and intensive sessions. CNC machined from high-strength steel and hardened to 60 Rockwell degrees according to manufacturer specifications, it provides precise tooth engagement for a clean interaction with a 520 pitch chain.
The Pro series is distinguished by lightweight holes and mud evacuation grooves on each side: these features limit dirt accumulation and help preserve the longevity of the sprocket and chain. The black zinc finish protects against light corrosion from washing and gives a sleek, polished look to the drivetrain.
