DescriptionRFX Pro Series Elite Aluminium - 520 Sprocket

Product details :

Features

The RFX Pro Series Elite aluminum 7075 sprocket brings a racing finish to the 520 transmissions of motocross and enduro machines. CNC machined and anodized in red, it features a sleek look with the RFX logo laser-engraved and a CAD-optimized profile to reduce weight without sacrificing rigidity.

Designed to shed mud with specific grooves, this sprocket extends the lifespan of the chain and facilitates maintenance in muddy conditions. Its rigid construction increases resistance to twisting, and tighter tolerances contribute to more accurate transmission behavior.

Manufacturer reference: FXRS 10-46 99RD
Brand: RFX
Material: Aluminum 7075, CNC machining
Chain pitch: 520
Number of teeth: 46
Color: Anodized red
Usage: Motocross / Enduro

Compatible with many recent Honda 450 models — including CRF 450 R, RWE, and RX Enduro (2026 models) — this RFX sprocket is aimed at riders looking for a robust, lightweight, and easy-to-maintain component. Check the pitch and number of teeth before installation for a perfect fit.
