At DMG Motorsports, we present the EK Chain SRO6 O-Ring 520 100' Roll (520SRO6-1920) — a bulk supply option for shops and riders who need a dependable, value-priced O-ring chain without compromising on quality or durability. Built in Japan to EK's exacting standards, this 100-foot roll of 520 pitch chain is ideal for dirt, ATV, and street applications, giving you the flexibility to cut custom lengths for multiple builds or repeat installs.

Engineered with high-tech, heat-treated steel alloys, the SRO6 series locks in lubrication and locks out dirt, water, and mud thanks to its high-quality O-ring seals. Solid rollers and extended anti-kink bushings help the chain resist stretching and kinking over time, extending service life even under demanding off-road and street riding conditions. Every link is assembled with EK's precise quad-staked riveting process, securing pins into the side plates for maximum strength and reliability. Whether you're outfitting dirt bikes, ATVs, or street machines rated up to 650cc, this chain delivers the strong tensile performance EK is known for.
