Features

RFX Race Sprocket 11 Teeth — compact and designed for motocross competition, this RFX front sprocket is CNC machined from alloy steel and then carburized to 60 Rockwell for high wear resistance. Its short tooth count (11 teeth) is suitable for gearing adjustments on small displacement and mini bikes, where every throttle response counts.

Designed for riders seeking precision and reliability, this sprocket offers very tight machining tolerances for smooth engagement with 415 pitch chains. Its silver finish and potential lightening holes (present on some models) reduce unsprung mass without compromising strength.

Material: carburized alloy steel
Treatment: carburizing to 60 Rockwell
Number of teeth: 11
Chain pitch: 415
Version: standard
Color: silver

Compatibility (examples): KTM 50 SX MINI (2023), HUSQVARNA TC 50 MINI (2023), KTM 50 SX (2023). Check compatibility with your output shaft before installation.

Manufacturer reference: FXFS 57-11 55ST
