The EK/PBR 520SRX2 13/49 chain kit is a set designed for off-road and motocross practices, created to replace the transmission drive train with ease. It combines a 520 pitch chain and a standard steel sprocket, mounted here in a 13 teeth sprocket / 49 teeth sprocket configuration, suitable for enduro/cross architectures requiring robustness and ease of maintenance.
Designed for easy installation on motocross bikes (e.g., SHERCO SE 300 I-F FACTORY 2013), this kit is a practical solution to restore the transmission. The gold finish aids in visual identification and adds an aesthetic touch to the swingarm. Ensure proper tension adjustment and suitable lubrication to optimize chain performance and limit wear on the sprockets and the sprocket.
