EK 520 SRX Gold Quadra-X Ring Chain | By EK Chain | For Electric and Street Motorcycles Using 520 Chain

High-Value Performance Chain with Proven Strength and Extended Wear Life

The EK 520 SRX Gold Quadra-X Ring Chain is a reliable, high-value drivetrain upgrade for riders running a 520 chain setup. Designed for street motorcycles up to 750cc and well suited for high-torque electric motorcycles, the SRX series delivers dependable strength, smooth operation, and long service life at an accessible price point.

Built with EK’s Quadra-X Ring sealing technology, the SRX chain reduces internal friction while sealing lubrication more effectively than a standard O-ring design. This results in smoother power transfer and a chain life that lasts 1.5 to 2 times longer than traditional O-ring chains, especially under consistent load and torque.

Key Features

  • Quadra-X Ring sealed chain for reduced friction and extended chain life
  • Rated for street motorcycles up to 750cc
  • Compatible with all bikes using a 520 chain
  • Lightening holes in side plates to reduce rotating mass
  • Smooth and consistent power delivery
  • Gold finish for corrosion resistance and clean appearance

Why Choose the EK SRX Series

The SRX series is built for riders who want dependable performance without stepping into full race-level pricing. With strong tensile strength and reduced friction, this chain is an excellent option for electric motorcycles and street builds that demand durability, smooth response, and long-term reliability.
