EK Chain 530SRX2130G SRX2 530 Quadra X-Ring Drive Chain 130 Links Gold

The EK Chain 530SRX2 is a premium Quadra X-Ring motorcycle drive chain in a gold finish, offered in a 130-link length for high-performance street and off-road applications. Built by Enuma Chain — a Japanese manufacturer with decades of chain engineering expertise — the SRX2 series represents an excellent balance of performance, durability, and value.

At the core of the SRX2's performance is EK's patented Quadra X-Ring (QX-Ring) seal design, which features a four-point contact patch that dramatically outperforms conventional O-ring chains. Lab testing demonstrates that the QX-ring reduces friction by up to 40% due to its smaller contact area, while simultaneously providing superior lubrication retention and contamination resistance. The result is a chain that lasts up to 50% longer than a standard O-ring chain.

Key Features:

• Quadra X-Ring (QX-Ring) seal technology — reduces friction by up to 40% vs. standard O-ring chains
• Extended service life — lasts 1.5 to 2 times longer than conventional O-ring chains
• Lightening holes on side plates — reduce rotating mass by approximately 3% without sacrificing strength
• Average tensile strength: 9,000 lbs — rated for street motorcycles up to 1,000cc
• Gold zinc-plated finish — corrosion resistance with a premium appearance
• 130 links — suitable for a wide range of street motorcycle applications
• Includes EK's patented screw-type master link — no riveting tool required for installation
• Made in Japan — manufactured to strict ISO-certified quality standards

The 530SRX2 is well-suited for high-output street machines, including sport bikes and standard motorcycles in the 600cc–1,000cc class. Whether used as a direct OEM replacement or as a performance upgrade, the SRX2 delivers reliable power transfer and long service intervals.
