EK CHAIN 520MRD7 transmission chain, designed for demanding riders who want a reliable transmission both on the track and on the road. Engineered to minimize friction while providing strong resistance to traction and abrasion, this 520 is suitable for the demanding environments of motocross but also fits quads, roadsters, and urban bikes.
Its golden coating makes it easy to spot and adds an aesthetic touch to your transmission. Ideal for common sprocket/crown configurations, it will particularly suit machines like YAMAHA YZ 450 F (2026), SUZUKI RM-Z 450 (2026), and HUSQVARNA FE 501 (2025), among other cross and trail models.
Before installation, check the length (number of links) and compatibility with your sprocket and crown. As always, regular maintenance (cleaning and lubrication) will extend the life of your chain and maximize the safety and precision of the transmission.
