Available in 110 to 120 links, it is engineered specifically for high-performance road and supersport motorcycles where reliable power transfer is non-negotiable.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eTensile strength of 41.6 kN (9,352 lbs) — handles sustained high-torque demands from powerful engines without compromise\u003c\/li\u003e\n\u003cli\u003eQX2-Ring seal technology locks lubricant inside each link and keeps contaminants out, reducing wear and extending service intervals\u003c\/li\u003e\n\u003cli\u003eZ\/3D (ThreeD Z-Series) construction adds dimensional rigidity, keeping the chain tracking true under hard acceleration and heavy loads\u003c\/li\u003e\n\u003cli\u003eGold\/Gold finish provides corrosion resistance alongside a clean, sporty appearance that holds up over daily kilometres\u003c\/li\u003e\n\u003cli\u003eSupplied open with a rivet link for maximum security — the preferred connection method for high-output machines\u003c\/li\u003e\n\u003cli\u003eAvailable in your choice of link count (110–120) to suit a wide range of 520-pitch drivetrain configurations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eEveryday Performance You Can Rely On\u003c\/h2\u003e\u003cp\u003eWhat separates a premium chain from a budget option is not just peak figures — it is how the chain behaves over thousands of road kilometres. With a relative service life rating of 3500 per 100 links and a weight of just 1.69 kg per 100 links, the EK 520 Z\/3D sits at a practical sweet spot: light enough not to burden your drivetrain, strong enough to outlast lesser chains by a meaningful margin. Riders who commute on their supersport or tour on their naked bike will notice the smoother, quieter running and the reduced need to reach for the chain lube.\u003c\/p\u003e\u003ch2\u003eQX2-Ring Technology in Detail\u003c\/h2\u003e\u003cp\u003eThe QX2-Ring seal is a step beyond a standard O-ring. Its geometry creates a more consistent sealing surface between the inner and outer plates, which translates directly into reduced friction, more effective grease retention and a longer replacement interval. For road riders, that means fewer garage sessions and more time riding — without sacrificing reliability.\u003c\/p\u003e\u003ch2\u003eZ\/3D Construction and the Rivet Link\u003c\/h2\u003e\u003cp\u003eEK's ThreeD Z-Series design optimises the geometry of plates and pins to distribute stress more evenly across the chain under load. The result is a chain that resists stretching and side-flex even when paired with the higher torque outputs of modern inline-four and V-twin supersport engines. The open configuration with a rivet link ensures a fixed, permanent connection that does not rely on a clip, making it the right choice for any machine where a dropped chain link is not an option.\u003c\/p\u003e\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\u003cp\u003eThis chain uses a 520 pitch and is available in 110 to 120 links, covering a broad range of road and supersport models.
