The EK 520SRX2-130 SRX2 Quadra X-ring chain is designed for street motorcycles and sport bike applications that demand dependable performance and extended service life. This 520-size chain features a 130-link configuration and is engineered as an excellent value for a wide range of street machines. The EK SRX2 series combines efficient power transfer with durable construction for everyday riding and performance-focused use.
Its Quadra X-ring seal design helps reduce friction while retaining lubrication more effectively than a standard O-ring chain. According to the manufacturer, the design can provide chain life approximately 1.5 to 2 times longer than a conventional O-ring chain when properly installed, lubricated, and maintained. Lightening holes in the side plates reduce weight by approximately 3 percent, helping support responsive handling without compromising the chain’s intended street-bike performance.
Fitment should be verified against the motorcycle manufacturer’s specifications, including chain size, required link count, gearing, and sprocket compatibility. The EK 520SRX2-130 is intended for compatible 520-drive sport bikes and street motorcycles; it may require cutting and riveting or the appropriate master link installation method.
