EK 520 MVXZ Quadra-X Ring Chain 130 Link | By EK Chain | For Street and Electric Motorcycles Using 520 Chain
High-Performance Chain Built for Strength, Efficiency, and Long-Term Reliability
The EK 520 MVXZ Quadra-X Ring Chain is a proven upgrade for riders who want smooth power delivery, reduced friction, and long service life. Designed as a direct replacement for any motorcycle or e-moto running a 520 chain, the MVXZ is equally at home on high-powered street bikes and modern electric motorcycles that demand strength and consistency.
At the core of this chain is EK’s proprietary Quadra-X Ring sealing technology. Compared to a traditional O-ring chain, Quadra-X Rings reduce internal friction while sealing lubrication more effectively. This results in smoother drivetrain operation and 1.5 to 2 times the wear life of a standard O-ring chain, even under hard riding and high torque loads common with electric bikes.
Key Features
Quadra-X Ring sealed chain for reduced friction and extended chain life
Compatible with all bikes using a 520 chain
Lightening holes in side plates to reduce rotating mass
Large diameter pins for increased tensile strength
Smoother throttle response and power transfer
Excellent resistance to stretch and long-term wear
Why Choose the MVXZ Quadra-X Ring Chain
Electric motorcycles place instant torque loads on the drivetrain, which can quickly wear out lower-quality chains. The MVXZ is built to handle those loads while minimizing friction and maintenance. For riders who want reliability, longevity, and smooth performance across both gas and electric platforms, this chain is a solid, proven choice.
