The EK 525 SRX2 Series Chains incorporate advanced QX-rings that significantly outperform traditional O-ring chains. Laboratory tests have shown that QX-rings reduce friction by 40 percent, resulting in up to 50 percent longer lifespan compared to standard O-ring chains. Weight-saving holes are drilled into every other chain link to minimize rotating mass without compromising strength, delivering more horsepower to the rear wheel and improving throttle response.
Includes a patented screw-type master link for easy installation without special tools, providing a rivet-like fit
QX-ring technology for reduced friction and longer lifespan
Compatible displacement: 1000cc Street / 750cc Dirt
