RFX Race Sprocket 13 Teeth — Manufacturer part number: FXFS 14-13 55ST. Designed for motocross use, this RFX front sprocket is CNC machined from alloy steel and carburized for high hardness and good wear resistance. Its silver finish and robust design make it a reliable component for those seeking engagement precision and longevity on trails or circuits.

The choice of a 13-tooth sprocket influences the gearing: a shorter ratio for quicker revs and a sharper throttle response. RFX maintains tight machining tolerances for consistent contact with the chain and limits vibrations transmitted to the drivetrain.
