EK 520 3D MXR Chain Gold - 120L

Introducing the EK 520 3D MXR Chain Gold - 120L, a premium motorcycle chain crafted for riders who demand reliability, standout style, and peak performance. Built for 520-pitch drivetrains, this 120-link chain is a versatile choice for sport machines, naked bikes, and high-performance street builds that call for precise power transfer and exceptional durability.

The striking gold finish isn’t just for show—it’s a durable coating designed to resist road grime, moisture, and the elements you encounter on daily commutes or weekend rides. Combined with EK’s advanced 3D MXR design, this chain distributes loads more evenly across each link, reducing wear on both the chain and the sprockets and helping your drivetrain stay quiet and responsive mile after mile.
