RFX Race Sprocket 12 Teeth - Manufacturer Ref: FXFS 20-12 55ST
Designed for motocross riders who pay close attention to their transmission, this RFX front sprocket combines precision machining and robust material. CNC machined from alloy steel, it is carburized and heat-treated with a hardness of 60 Rockwell, ensuring excellent wear resistance. Its silver finish gives it a sleek and technical look on the bike.
The choice of a 12-tooth sprocket allows for gearing adjustments to prioritize acceleration and responsiveness at low and mid-range RPMs, while still being a standard sprocket version suitable for motocross setups. Some RFX models feature weight-saving holes to reduce rotating mass without compromising strength.
