EK 520 SRX2 Quadra X-Ring Motorcycle Chain
The EK 520 SRX2 is a premium Quadra X-Ring chain engineered for both competition use and OEM replacement. Featuring lightening holes for reduced rotating mass, a low-friction design, and EK’s proprietary Quadra X-Ring seal technology, the SRX2 delivers 1.5–2x the service life of a standard O-ring chain — making it one of the best value performance chains available for sport bikes, mini bikes, and high-performance street builds.
