EK CHAIN 520MRD7 520 (ref. 520MRD7-G/G 106 SPJ) — a transmission designed for riders who push their machines, from the motocross track to the city. This 520 chain in a double-sided gold finish features 106 links and a profile designed to minimize friction losses while providing good resistance to abrasion and traction. Compact and robust, it fits demanding machines without compromising routine maintenance.
Designed to withstand the demands of challenging environments, this chain is suitable for quad, urban, motocross, and roadster uses. It is particularly well-suited for powerful and versatile motorcycles — examples include models like the YAMAHA YZ 450 F (2026), the SUZUKI RM-Z 450 (2026), or the HUSQVARNA FE 501 (2025) — subject to verification of the number of links and transmission setup.
For optimal longevity: regular tension checks, appropriate lubrication, and inspection of the links and sprocket. The gold finish also adds a polished look to your transmission while facilitating visual wear detection.
