The EK/PBR 520SRX2 13/49 - ultra-light sprocket kit is designed for motocross riders looking for a reliable and subtly high-performing set. Created by EK CHAIN, this kit combines the longevity of the SRX series with a lightweight aluminum sprocket, engineered for off-road conditions.
This kit is suitable for off-road practices and routine maintenance interventions: complete replacement of chain/sprocket/crown to restore a safe and uniform drive system. The ultra-light aluminum sprocket helps to slightly reduce rotating mass without compromising ease of installation.
