Premium Chain Kit with EK 525Z/3D ThreeD Chain

This premium chain kit combines the advanced technology of the EK 525Z/3D ThreeD drive chain with a precision-engineered JT steel front sprocket and a JT steel rear sprocket. Developed for high-performance street motorcycles, the EK ThreeD chain delivers outstanding tensile strength, reduced weight and exceptional durability.

The ThreeD series features precision-forged outer plates with a unique three-dimensional design. This innovative construction increases chain rigidity while reducing weight, resulting in improved power transmission and riding performance. The proven QX2 sealing rings effectively retain lubricant inside the chain while preventing dirt and moisture from entering, reducing friction and extending service life.

Special chromium carbide pin treatment minimizes wear between pins and bushings, ensuring smooth operation even under demanding conditions. With a tensile strength of 44.5 kN, a weight of only 1.90 kg per 100 links and a relative wear life rating of 3600, the EK 525Z/3D is one of the finest motorcycle chains in its class and is recommended for street motorcycles up to 1200 cc.

The included JT steel front sprocket and JT steel rear sprocket are manufactured from high-quality C49 high-carbon steel and heat-treated for outstanding wear resistance and precise power transmission. Manufactured to OEM specifications, JT sprockets perfectly complement the premium characteristics of the EK ThreeD chain, providing a reliable, durable and low-maintenance final drive for everyday riding, touring and sporty road use.
