EK Chain 520 VG/3D Chrome NX-Ring Chain – Open with Rivet Link, 110 to 120 Links

When reliability and longevity matter as much on race day as they do on every spirited road ride, the EK 520 VG/3D NX-Ring chain in chrome delivers a level of engineering that justifies its place in any serious build. Weighing just 1.52 kg per 100 links and rated to a tensile strength of 39.6 kN, this is a chain that earns its keep across every kilometre.

Key Features

• NX-Ring seal technology reduces friction and internal wear compared with conventional O-rings, extending service life to a relative durability rating of 3600 per 100 links
• VG/3D construction distributes load evenly across the chain, maintaining structural integrity under sustained high-stress conditions
• At 1.52 kg per 100 links, reduced rotating mass translates directly into sharper acceleration response and more predictable power delivery
• Chrome finish provides a clean, premium appearance while adding a layer of protection against corrosion and environmental exposure
• Supplied open with a rivet link — the preferred connection method in motorsport for its uncompromising security under extreme loads
• Available in six link counts from 110 to 120, covering a wide range of sprocket combinations and swingarm configurations

NX-Ring Technology: Everyday Gains, Long-Term Value

The NX-Ring seal is not merely a racing specification — it is a practical advantage for any rider who wants fewer maintenance intervals and more consistent performance over the chain's working life. By reducing the friction that conventional O-rings generate, the NX-Ring keeps internal lubrication where it belongs and slows the wear that shortens chain life. The result is a relative durability figure of 3600 per 100 links, meaning you replace the chain less often and spend more time riding.

VG/3D Construction and Tensile Strength

The VG/3D designation refers to EK Chain's three-dimensional plate geometry, engineered to increase the structural rigidity of each link without adding unnecessary mass. Combined with a tensile strength of 39.6 kN, the chain handles the shock loads generated by aggressive gear changes, hard acceleration and high-horsepower power units without deforming or stretching prematurely. Whether the application is a track-focused superbike or a highly tuned road machine, the VG/3D construction keeps power transfer consistent lap after lap.

Chrome Finish: More Than Cosmetic

The chrome finish on this EK 520 VG/3D is applied with function in mind as well as aesthetics. It provides a durable barrier against moisture and road contamination, reducing surface corrosion that can accelerate wear on the outer plates. On a bike where every component is chosen deliberately, a chain that holds its condition visually and mechanically over time is a practical choice, not an indulgence.

Open Chain with Rivet Link

This chain is supplied open, with a rivet link included for fitment. Rivet-type connecting links are the standard in circuit and competition environments because, once correctly installed, they offer the same tensile integrity as the chain's pressed pins — there is no clip to dislodge under vibration or high-speed chain movement. Correct installation requires a quality chain riveting tool; if in doubt, have the chain fitted by a qualified mechanic.
