EK Chain 520 ZVX3 Gold/Gold NX-Ring Chain – Open with Rivet Link, 84 to 146 Links

Few chains carry the visual signature of the EK 520 ZVX3 in full gold/gold — a finish that speaks to the ZVX series' racing heritage as clearly as the engineering beneath it. Built for high-torque supersport and street machines, this NX-Ring chain delivers a tensile strength of 41.8 kN (9,400 lbs) and a relative service life rating of 3,900, placing it well above any standard OEM replacement.

Key Features

• Full gold/gold surface treatment adds corrosion resistance and a premium aesthetic that stands apart on any build
• NX-Ring seal technology locks in lubrication and minimises internal friction, extending service life and reducing wear
• Tensile strength of 41.8 kN (9,400 lbs) handles the demands of high-output engines without compromise
• Exceptional lateral rigidity keeps power transfer consistent under hard acceleration and sustained high-speed running
• Supplied open with a rivet link for a secure, permanent connection suited to performance and track use
• Available in 32 link counts from 84 to 146 links — choose the exact length for your sprocket combination

Design, Finish and Heritage

The gold/gold finish on the ZVX3 is not merely decorative. The surface coating acts as an additional barrier against moisture and road contamination, keeping the chain looking sharp while contributing to longevity. EK Chain's ZVX series has long been associated with Japanese precision engineering and motorsport-grade standards, and the gold colourway carries that legacy with a distinct visual identity — at home on a track-day machine as much as a polished street build.

NX-Ring Technology

EK's NX-Ring seal sits at the heart of what separates the ZVX3 from conventional chains. The seals maintain optimal grease distribution between the pin and bush across the full service life of the chain. The practical result is reduced wear at every link, less frequent lubrication intervals and a relative service life rating of 3,900 per 100 links — a figure that reflects real-world durability rather than laboratory optimism.

Built for High-Performance Engines

The ZVX3's construction prioritises rigidity and load tolerance above all else. Under the sustained torque of a litre-class supersport engine or the punishing acceleration of a track-prepared middleweight, the chain maintains dimensional stability and consistent power transfer. With a pitch of 520 and a weight of just 1.8 kg per 100 links, the balance between strength and mass is well-judged for performance use on both road and circuit.

Rivet Link Connection

The chain ships open and includes a rivet link closure. This method of connection creates a joint that matches the strength of the chain itself — there is no reliance on a clip that can be displaced under vibration or load. For riders running the ZVX3 on track or in demanding street conditions, the rivet link is the appropriate choice.

Beyond OEM

Compared to a factory-fitted chain, the ZVX3 offers a measurable step up across every relevant metric: higher tensile strength, greater wear resistance, improved power transfer efficiency and a substantially longer service life. For any rider investing in quality sprockets or a full chain kit, the ZVX3 is the chain the rest of the drivetrain deserves.
