EK/PBR 520M3 Chain Kit 13/50 - Ultra-Light Sprocket
Designed for off-road and motocross competition, this chain kit combines a 520M3 gold chain with an ultra-light aluminum sprocket. It is aimed at riders looking for a reliable, lightweight transmission tailored to the specific demands of off-road riding without false technical promises.

The combination of the 520M3 chain and aluminum sprocket reduces rotational weight and unsprung mass, which is felt during throttle changes and corner exits on loose surfaces. The kit is suited to the demands of motocross: regular maintenance, correct tension, and lubrication ensure optimal longevity. Ideal for replacing or upgrading the transmission on motocross machines.
