1147829010 EK 525 SPR/3D gold motorcycle chain 525 size 120 links

The EK 525 SPR/3D NX-Ring gold motorcycle chain (525 pitch) with rivet link represents the pinnacle of EK technology for high-performance street applications, engineered to deliver extreme strength, superior durability, and maximum transmission efficiency. Developed by EK Japan, it incorporates the advanced ThreeD Dynamic Design, optimizing the chain structure for the perfect balance between lightness and strength.

Through a precision 3D forging process, the chain reduces material in low-stress areas, minimizing stress and improving load distribution. The chamfered inner and outer plates and drilled lightweight pins provide up to 10% weight reduction, enhancing responsiveness and drivetrain efficiency.

The NX-Ring sealing system ensures optimized internal lubrication, reducing friction and wear while delivering exceptional lifespan (wear index 4000). This guarantees consistent performance even during long-distance riding and intensive sport use.

With a tensile strength of 48 kN (10790 lbs), the EK 525 SPR/3D is one of the strongest chains in the range, making it ideal for mid to high-displacement motorcycles and high-performance street riding. The riveted master link ensures maximum safety, while the gold/gold finish delivers a premium racing look, recognized with the Good Design Award.

The EK 525 SPR/3D is the ideal choice for riders seeking a premium NX-Ring motorcycle chain with 3D technology, designed to deliver maximum durability, strength, and high performance on the road.
