EK CHAIN 520MRD7 520 – Manufacturer Ref: 520MRD7-G/G 112 SPJ
520 EK transmission chain in gold finish, designed for demanding off-road and on-road uses. The 520MRD7 is aimed at motocross, roadster, urban, and quad riders looking for a chain calibrated for robust transmission and a polished look. Its golden hue adds an aesthetic touch while remaining functional on sprocket and crown.
The MRD7 design from EK focuses on reducing friction between links while maintaining good abrasion and tensile strength. Suitable for transmissions equipped with a 520 pitch, this chain fits on sprocket-crown sets intended for motocross, enduro, roadsters, and quads. Check the number of links and compatibility with your sprocket for optimal installation and tension.
Examples of compatible motorcycles (for reference only): YAMAHA YZ 450 F (2026), SUZUKI RM‑Z 450 (2026), HUSQVARNA FE 501 (2025).
