1147831010 EK 520 RV/3D NX-Ring gold chain 520 pitch 120 links Off-Road

The EK 520 RV/3D NX-Ring gold motorcycle chain (520 pitch) with rivet link is a premium solution for off-road racing, enduro, and supermoto applications, designed to deliver maximum strength, lightness, and transmission efficiency. Developed by EK Japan, it features the advanced ThreeD Dynamic Design technology, engineered to optimize the balance between performance and durability.

Thanks to the 3D precision forging process, the chain structure reduces material in low-stress areas, minimizing mechanical stress and improving overall efficiency. The chamfered inner and outer plates and drilled lightweight pins provide up to 10% weight reduction, enhancing acceleration, responsiveness, and smooth power delivery.

The NX-Ring sealing system ensures optimized internal lubrication, reducing friction and extending lifespan (wear index 3500). This allows consistent performance even under the harsh conditions typical of off-road riding.

With a tensile strength of 39.6 kN (8903 lbs), the EK 520 RV/3D is built to handle high loads and intensive use. The riveted master link ensures maximum safety in racing conditions, while the gold/gold finish adds a distinctive racing look, recognized with the Good Design Award.

The EK 520 RV/3D is the ideal choice for riders seeking a premium off-road motorcycle chain with NX-Ring and 3D technology, delivering maximum durability, strength, and performance in enduro and supermoto racing.
