RFX Race Sprocket 14 Teeth (Manufacturer Part Number: FXFS 33-14 55ST)

Designed for the motocross world, this RFX front sprocket combines precision machining and robustness. CNC machined from alloy steel and then carburized to achieve a high surface hardness (≈60 HRC), it withstands wear better and endures the repeated stresses of off-road outings. Its silver finish adds a sleek and technical look to your transmission.

A 14-tooth sprocket shortens the gearing: more responsiveness at low and mid-range RPM, better acceleration recovery — ideal for winding tracks and frequent bursts in motocross. Mounted on a 520 pitch chain, this standard sprocket easily integrates into compatible transmissions without heavy modifications.
