EK Chains 520 MVXZ X-Ring Chain - 120 Links - Main

Product Description

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.
  • 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 9,000 pounds.
  • Wear life index: 1,500.
  • Maximum displacement (dirt): 750cc.
  • Weight (per 100 links): 3.99 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.

Note for installing X-ring chains: As X-ring chains are wider than standard roller chains, when fitting an X-ring chain to a motorcycle that was fitted with a non O-ring chain as original equipment, it is essential to check that there is proper clearance of the engine cases near the countershaft sprocket and any other places of close contact. Failure to do so could result in damage to the chain and motorcycle and could ultimately cause the chain to fail.

Great chain, week color

I got the red chain and most of the red wore off after one ride I would just but standard color next time.

I have a trx 250x with a 14 tooth front sprocket and 36 tooth rear sprocket...I'm looking at a chain 520 120 link during and wondering if the stock ch?
Is the stock length chain going to accommodate my sprocket changes?? If not could you reference me to the appropriate size...for 134$ I don't need to be knocking out links...thanks

I wouldn't be able to tell you for certain if your stock chain would work on that sprocket combination. From what I can find your stock chain length would be 86 links. Most of the chains we sell for ATV's would be 100-120 Links, we do not carry a chain that is specifically cut to length for your 1987 Honda TRX250X
