RFX Race Sprocket 13 Teeth (manufacturer part number: FXFS 82-13 55ST): a front sprocket designed for motocross riders seeking reliable and precise transmission. CNC machined from high-strength alloy steel and then carburized (claimed hardness), this sprocket offers a clean cut finish and tight tolerances for good chain engagement and controlled wear. Its silver hue gives it a sleek and technical look on the wheel output.

Designed for a chain pitch of 520, this 13-tooth sprocket in standard version allows for adjustments to engine character for sharper starts and increased torque at low RPM — ideal for rough terrain or strong acceleration on enduro/motocross courses.
