EK Chain 520MVXZ2120R 520 MVXZ2 Quadra-X Ring Drive Chain 120 Links Red

The EK Chain 520 MVXZ2 Quadra-X Ring Drive Chain is a premium 520-pitch motorcycle drive chain featuring 120 links in a bold red finish. Engineered for high-performance street and off-road riding, the MVXZ2 delivers superior durability and smooth power transfer through EK's advanced sealing and construction technology.

At the heart of the MVXZ2 is EK's proprietary Quadra-X Ring (QX-Ring) sealing system, which provides a greater sealing surface and significantly less friction than standard O-ring chains. This innovative design keeps internal lubrication sealed where it belongs, reducing wear and extending chain life by up to 1.5 to 2 times compared to a conventional O-ring chain.

Key Features:

• Zero Stretch Technology — eliminates measurable chain stretch during the first 600 miles of use for consistent, precise drivetrain performance
• Quadra-X Ring (QX-Ring) seal — reduces friction by up to 40% and dramatically increases wear life versus standard O-ring chains
• Lightening holes in side plates — reduce overall chain weight without sacrificing strength
• Large-diameter pins — provide greater tensile strength and resistance to fatigue
• Tensile strength: 9,000 lbs (40 kN) — built for demanding street and off-road applications
• Chain size: 520 pitch | Links: 120 | Color: Red
• Master link: Rivet-type included; clip-type (semi-press) or screw-type master links available separately

The MVXZ2 is an ideal OEM-replacement chain for 600–1000cc street motorcycles and up to 750cc off-road/dirt applications. The red finish adds a distinctive, factory-works appearance to any drivetrain build.
