The EK 525SRX2-130G SRX2 series chain is a high-value replacement and upgrade for street motorcycles and sport bikes requiring a 525-size drive chain. Finished in gold, this 130-link chain combines durable construction with reduced friction for dependable performance during everyday riding, spirited road use, and routine street-machine applications.
Its Quadra X-ring design helps retain lubrication while reducing friction at the sealing points. Compared with a standard O-ring chain, the SRX2 design can provide approximately 1.5 to 2 times longer service life when properly installed, lubricated, and maintained. Lightening holes in the side plates reduce chain weight by approximately 3 percent without sacrificing the practical strength needed for compatible motorcycle applications.
Use the EK 525SRX2-130G only on motorcycles specified for a 525 chain size and confirm the required link count, gearing, and manufacturer fitment recommendations before installation. The chain may be cut to the required length by a qualified installer using the correct chain tool, and it should be paired with compatible sprockets. This product is manufactured by EK and is identified by manufacturer part number 525SRX2-130G and vendor part number 693-1830G.
