EK/PBR 520MRD7 13/52 Chain Kit - Standard Sprocket by EK CHAIN. Specifically designed for motocross use, this chain kit combines chain and sprocket/crown for a complete overhaul of your motorcycle's secondary transmission.
The kit provides a robust solution to meet the demands of off-road riding: the 520 pitch chain adapts to the tight ratios of motocross machines, while the steel crown ensures longevity and stability on muddy and rocky tracks. The gold finish (Gold/Gold) makes it easy to spot and gives the bike a racing look.
Compatible with many motocross models, including TM RACING EN 300 (2007–2009). Installation and adjustment should follow manufacturer recommendations: check the tension adjustment and alignment during installation to ensure reliable transmission on the field.
