EK/JT 520M3 Chain Kit 13/50 - Ultra-Light Sprocket
Designed for the demands of motocross, this EK CHAIN kit combines a 520M3 chain with an ultra-light aluminum rear sprocket. Engineered to minimize friction while maintaining good tensile strength and abrasion resistance, it is aimed at riders looking for a lightweight and reliable transmission on challenging terrains.
Classic installation and adjustment: check tension and lubrication after the first few kilometers. Ideal for the motocross universe and compatible with models such as KTM 250 SX / 250 SXS (2004).
