The EK 525SRX2-150 SRX2 Quadra X-ring chain is designed for street motorcycles and sport bikes requiring dependable power transfer, reduced friction, and long-lasting performance. As part of EK’s SRX2 series, this 525-size chain provides an excellent value for riders seeking a durable replacement chain for everyday street use, commuting, or spirited riding.
The Quadra X-ring design helps reduce friction at the sealing points while retaining lubrication more effectively than a standard O-ring chain. This construction can provide chain life approximately 1.5 to 2 times longer than a conventional O-ring chain when properly installed, adjusted, and maintained. The chain includes 150 links and is suited for compatible motorcycle applications using a 525 chain size.
Lightening holes in the side plates reduce weight by approximately 3 percent without sacrificing the chain’s intended street performance. Verify motorcycle fitment, chain length, sprocket compatibility, and manufacturer recommendations before installation. The manufacturer part number is 525SRX2-150, and the vendor part number is 693-1850.
