EK/PBR 520MRD7 Chain Kit 12/48 - Ultra-light Sprocket
A chain kit designed for motocross: the 520MRD7 from EK CHAIN combines a treated gold-colored chain with an ultra-light aluminum sprocket (48 teeth) and a 12-tooth pinion. Designed to reduce friction and limit wear on demanding tracks, this kit offers a balance between lightness and robustness suitable for riders who heavily rely on their transmission.
Ideal for motocross machines such as the SUZUKI RM-Z 250 (2007–2009), this kit is aimed at riders looking for a lightweight and precise transmission. Replace the pinion and sprocket simultaneously to optimize the chain's longevity and maintain a smooth and efficient transmission on the track.
