With a tensile strength of 45.8 kN (10,300 lbs), a riveted master link for maximum connection security, and a relative service life rating of 4000 per 100 links, it sets a benchmark that standard OEM chains simply cannot match.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e45.8 kN (10,300 lbs) tensile strength — designed for high-output litre-class machines and heavy torque loads\u003c\/li\u003e\n\u003cli\u003eNX-Ring seal technology minimises internal friction and retains lubrication for dramatically reduced wear\u003c\/li\u003e\n\u003cli\u003eRelative service life rating of 4000 per 100 links — well above conventional OEM-spec chains\u003c\/li\u003e\n\u003cli\u003eZVX3 construction delivers exceptional lateral rigidity and consistent power transfer under sustained load\u003c\/li\u003e\n\u003cli\u003eSupplied open with a rivet link for the most secure possible master-link connection on performance motorcycles\u003c\/li\u003e\n\u003cli\u003eClassic steel\/steel finish — functional, understated, and highly resistant to everyday road conditions\u003c\/li\u003e\n\u003cli\u003eAvailable from 94 to 146 links to cover a vast range of 525-pitch applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eNX-Ring Seal Technology\u003c\/h2\u003e\u003cp\u003eEK's NX-Ring seals represent the brand's highest-grade sealing solution in this chain family. Unlike conventional O-rings, the NX-Ring profile creates a more effective contact surface that keeps grease locked inside each link's pin-and-bushing interface. The result is measurably lower friction, far slower elongation over time, and service intervals that experienced riders will notice immediately when switching from a budget chain. At just 2.05 kg per 100 links, this level of durability comes without a weight penalty you can feel.\u003c\/p\u003e\u003ch2\u003eZVX3 Construction and Rivet Link Security\u003c\/h2\u003e\u003cp\u003eThe ZVX3 designation identifies EK's premium road and track chain series — a construction that prioritises lateral stiffness and plate-to-plate consistency across every link. A stiff chain tracks accurately through sprocket teeth, reduces vibration transmitted to the swingarm, and transfers torque more smoothly than a chain that flexes laterally under load. This matters most when exiting corners hard or accelerating through the mid-range on a powerful inline-four or V-twin.\u003c\/p\u003e\u003cp\u003eThe chain is supplied open with a rivet link rather than a clip-type master link. Riveted connection is the preferred standard on any high-performance application because it eliminates the risk of a clip working loose under repeated load cycles. Fitting requires a chain breaker and riveting tool, which is the correct approach for this class of motorcycle.\u003c\/p\u003e\u003ch2\u003eSteel\/Steel Finish\u003c\/h2\u003e\u003cp\u003eThe steel\/steel colour combination is the definitive functional choice. There are no anodised or coloured plates to chip or fade — just clean, uniform steel throughout. It suits any bike where durability and precision engineering take priority over aesthetics, and it ages gracefully without showing cosmetic wear the way coloured chains do.\u003c\/p\u003e\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\u003cp\u003e525 pitch, available in 94 to 146 links.
