Designed for demanding riders, this RFX front sprocket in silver steel delivers the machining precision expected from a 520 transmission. CNC machined and hardened to 60 Rockwell, it offers a hard surface and a refined core to minimize wear in both road and off-road conditions. Its "standard" design makes it a reliable component for adjusting the gearing without compromising chain integrity.

RFX focuses on tight tolerances achieved through CNC machining — a noticeable advantage in transmission feel and acceleration precision. Some sprockets in the range are also drilled to lighten the part; check the product photo to confirm the finish. Suitable for Quad, Cross, and Roadster environments, this sprocket is particularly compatible with high-performance machines listed in the manufacturer's compatibility references.

Replace your original sprocket with this model to regain a sharper throttle response and a straightforward gearing adjustment without any modifications: a pragmatic choice for those seeking reliability and machining quality in their transmission chain.
