The EK/PBR 520MRD7 13/50 chain kit is designed for motocross riders seeking a reliable and lightweight transmission. Built for cross competition, this kit combines a gold 520 chain with an ultra-light hard anodized aluminum sprocket: reducing weight at the rear wheel without sacrificing wear resistance. The gold finish on the chain and sprocket provides a polished look and protection against corrosion.
Simple installation and maintenance for intensive cross use: the combination of anodized aluminum + treated chain reduces friction and offers good resistance to abrasion and traction, which is beneficial during jumps, accelerations, and muddy terrains. This kit is suitable for gearbox ratio adjustments to optimize acceleration and traction out of corners.
