The EK 525SRX2-120G SRX2 series motorcycle chain is designed for street machines that need dependable performance, smooth power transfer, and long service life. This 525-size chain features a gold finish and includes 120 links for compatibility with properly specified motorcycle drivetrains. EK manufactures the SRX2 series for riders seeking a practical balance of durability, reduced friction, and value.
Its Quadra X-ring seal design helps reduce friction at the sealing points while retaining lubricant more effectively than a standard O-ring chain. This design can provide a service life approximately 1.5 to 2 times longer than a conventional O-ring chain when properly installed, lubricated, and maintained. Lightweight holes in the side plates further reduce chain weight by approximately 3 percent without compromising the chain’s intended street-bike application.
Fitment includes select 2004–2009 Aprilia RSV1000R models and 2004–2007 Aprilia RSV1000R Factory models. Verify the motorcycle’s year, model, chain size, link count, sprocket configuration, and manufacturer specifications before installation. The manufacturer part number is EK 525SRX2-120G, and the vendor part number is 693-1820G.
