The EK 525 ZVX3 Sportbike Chain is designed for competition use and OEM replacement applications. This 160-link chain is built for high-performance sportbike drivetrains, providing a reliable connection between the engine and rear wheel when precise power transfer and durability are required. The black and gold finish adds a distinctive appearance while supporting the chain’s performance-focused design.
Engineered with reduced clearance between the plates, the EK 525 ZVX3 helps improve drivetrain control and operating stability. Its construction balances increased stiffness with reduced weight, making it well suited for riders and teams seeking responsive performance without unnecessary drivetrain mass. The NX ring design is rated to last 15% longer than the previous ZVX series chains, helping extend service life under demanding riding conditions.
This EK chain includes a rivet-style master link for secure installation when properly fitted and riveted according to the motorcycle manufacturer’s service procedures. It is intended for compatible 525-size sportbike applications and may be used as a replacement for an original-equipment chain when the motorcycle’s specifications call for this size, link count, and chain configuration. Always confirm fitment, required link count, and master-link installation requirements before installation. Manufacturer and vendor part number: 525ZVX3-160KG.
