Back in 1974, EK Chains introduced the world's first sealed O-ring chain. Quality is an obsession at EK Chains. In 1997, the company was certified to ISO 9001 quality management standards. This certification recognizes the high standards of the quality assurance system and reinforces EK's guarantee of safety and precision in every product they sell. Research and development at EK Chain has always focused on creating technological breakthroughs and developing original ideas, and a relentless commitment to innovation continues to drive everything they do.

  • The MVXZ chain is a Quadra-X Ring sealed chain.
  • An ideal replacement chain for any 600 to 1000cc street bike.
  • Perfect choice for any serious motocross application.
  • Features lightening holes in side plates and large diameter pins.
  • Quadra X-Ring design reduces friction by as much as 40% and increases chain life as much as 2 times longer than a standard O-Ring chain.
  • Average tensile strength of 9,300 pounds.
  • Wear life index: 1,500.
  • Maximum displacement (street / dirt): 1000cc / 750cc.
  • Weight (per 100 links): 4.21 pounds.
  • Includes a rivet-style master link.
  • 120 links.

Quadra-X Ring: Quadra-X Ring design reduces friction by as much as 40% due to a smaller contact area. The X-ring's 4-point contact patch also offers better sealing than conventional O-rings. Lab tests show the Quadra-X ring chains last 50% longer than a standard O-ring chain.

CRH Pin Treatment: EK's exclusive CRH pin treatment provides an extremely hard outside coating and softer inside to increase strength and reduce chain wear. The chromium-carbide pin surface coating also offers superior impact and shock absorption while reducing oxidation caused by exposure to nature's elements.

Lightening Holes: Lightening holes in the side plates reduce the chain's overall weight by 3% without compromising tensile strength. These holes also extend the service life by dissipating heat and helping reduce dirt and mud build-up.

Yes, you will need to remove links. The chains are sold in bulk lengths to allow for a variety of bikes and gearing. A chain breaker makes it quick and easy to remove links. http://www.motosport.com/cruiser/Motion-Pro-Chain-BreakerPressRiveting-Tool

What is the difference between a EK 525MVXZ Chain and a EK 520MVXZ Chain?
Are both chains compatible with a 2008 Kawasaki Ninja 650r?

The difference of the chains is in the size and pitch of the links. The 525 is the larger of the two chains. The 520 is the chain that is compatible with your 2008 Ninja 650R.
