Vortex Racing EK 520 SRX2 Clip Master Semi Press 104 Links- Natural - 520SRX2-104

The EK SRX2 Series Chains feature advanced QX-rings that outperform factory O-ring chains. Laboratory tests have demonstrated that QX-rings reduce friction by 40 percent, extending chain lifespan by up to 50 percent compared to traditional O-ring chains. Additionally, weight-saving holes drilled into every other chain link minimize rotating mass without compromising strength, enhancing horsepower delivery to the rear wheel and improving throttle response.
