RFX Race Sprocket 13 Teeth – Manufacturer Ref: FXFS 61-13 55ST
Designed for the demanding training of quads, motocross, and roadsters, this RFX front sprocket is CNC machined from high-strength alloy steel. It features a carburizing treatment up to 60 Rockwell to enhance wear resistance and lifespan against transmission stresses.
This sprocket provides a robust solution for adjusting your gearing, improving engine responsiveness, or replacing a worn component. The CNC machining ensures tight tolerances, which are essential for precise chain engagement and smooth torque transmission. Some RFX models are also equipped with lightweight holes to reduce rotating mass; please inquire based on the reference.
Common application examples: HUSQVARNA TE 449 (2014), HYOSUNG TE 450 Rapier (2010), BMW G 450 X (2010). Before installation, check compatibility with your engine shaft and chain kit (pitch 520).
