RFX Race Sprocket 15 Teeth — Manufacturer Ref: FXFS 32-15 55ST. Front sprocket made of steel designed for the transmission of demanding motorcycles and quads. Designed for mounting on a 520 pitch chain, this standard sprocket offers a robust solution to replace a worn component and maintain precise transmission.
RFX front sprockets are CNC machined from high-strength alloy steel and hardened to 60 Rockwell for better wear resistance. The machining controls tolerances for a round engagement and constant chain contact. Some models in the RFX range are equipped with lightweight holes to reduce rotating mass without compromising strength.
Suitable for Quad, Cross, and Roadster environments, this sprocket fits many drivetrains requiring a 15-tooth configuration in 520. Examples of common compatible models in the same category: YAMAHA YZ 450 F (2026), SUZUKI SV 650 X (2024), and KAWASAKI Z 650 ABS (2024). Replace your worn sprocket with this axle piece to achieve properly aligned chain and reliable engagement.
