The EK/PBR 520SRX2 14/48 - ultra-light sprocket kit is designed for motocross riders who want a complete, lightweight final drive that meets 520 specifications. Developed by EK CHAIN, this kit combines an SRX series chain with a sprocket and a crown optimized for off-road use.
This kit provides a complete solution for restoring the final drive: chain, sprocket, and crown are sized for a 520 installation. The ultra-light aluminum crown reduces inertia without adding weight, a benefit appreciated in motocross for acceleration and maneuverability. Particularly suitable for the off-road machines listed below.
For optimal safety and longevity, have the chain adjustment and installation checked by a professional or follow the manufacturer's recommendations for your motorcycle.
