EK Chain 520SRX2 QX-Ring 520 118 links

The EK 520SRX2 QX-Ring chain with 118 links is a top-level secondary transmission component, optimized to offer superior friction resistance and minimal wear under intensive use. The QX-Ring technology drastically reduces power loss due to friction compared to conventional O-Ring seals, achieving a more efficient seal that retains internal lubricant and prevents the entry of contaminants. This 520-pitch model is the ideal choice for motorcycles requiring an optimal balance between lightness, longevity, and torque transmission capacity. Thanks to its robust construction and heat treatment of the links, it ensures prolonged durability, minimizing the necessary tension adjustments. It is the perfect replacement part to improve the efficiency of the final drive system, ensuring constant power transfer and superior mechanical reliability on the road or track.
