The EK 525 ZVX3 Sportbike Chain is designed for competition use and OEM replacement applications on compatible sportbikes. This blue, 120-link chain is engineered to deliver dependable power transfer, improved durability, and consistent performance for riders who demand reliable drivetrain components. The 525-size chain is suitable for motorcycles specified for an EK 525 series replacement chain; confirm the original equipment chain size, link count, and sprocket compatibility before installation.
Featuring EK’s NX ring technology, the 525ZVX3-120AB is designed to maintain a tighter seal and minimize clearance between the plates. This helps retain lubrication and supports longer service life under demanding riding conditions. Compared with the previous ZVX series, the NX ring design provides an approximately 15% longer service life when properly installed, lubricated, and maintained.
The EK 525 ZVX3 also combines improved stiffness with reduced weight to support responsive handling and efficient drivetrain operation. The chain includes a rivet-style master link for secure installation, making it a practical choice for professional replacement, performance builds, and competition-focused maintenance. Use the manufacturer’s recommended riveting procedure and verify correct chain tension and alignment during installation.
