The RFX Race front sprocket with 13 teeth is a part designed for quad, motocross, and roadster riders looking for a reliable sprocket tailored for recreational competition. CNC machined from alloy steel and then case-hardened to 60 Rockwell, it features a silver finish and tight machining tolerances for a precise fit with the chain and the rear sprocket.
Designed to withstand wear, this sprocket endures the stresses of the primary drive and adheres to RFX specifications for machining quality. It is ideal for modifying the gear ratio and adapting the response of the drivetrain according to your usage—track outings, trails, or light road use.
