The RFX Race front sprocket 13 teeth (manufacturer reference: FXFS 32-13 55ST) is aimed at demanding riders looking for a reliable transmission part for quad, motocross, or roadster. Machined from cemented alloy steel using CNC technology, it features a hardness of 60 Rockwell for good wear resistance and precise alignment during installation. Its silver finish discreetly integrates with the gearbox output.
This front sprocket allows for adjustment of the final drive ratio: a common choice to adapt engine response and handling characteristics based on terrain or riding style. Designed to fit 520 configurations, it can be installed on many road and off-road machines when compatible with the gearbox output shaft.
Compatibilities (examples): YAMAHA YZ 450 F (2026), SUZUKI SV 650 X (2024), KAWASAKI Z 650 ABS (2024). Always check the chain pitch and bolt pattern before installation.
