At DMG Motorsports, we present the EK Chain SR Non-Sealed 520 25' Roll (520SR-480) — a heavy-duty, non-sealed 520 chain built by EK to deliver serious durability for lower horsepower dirt, ATV, and street applications. Sold as a full 25-foot roll, this chain gives shops and riders the flexibility to cut custom lengths for a wide range of builds. As the heavy-duty step up from EK's standard sport chain, the 520SR is engineered with solid bushings and solid rollers that hold up to demanding use, making it an ideal choice when you need more strength and wear life than a basic non-sealed chain can offer.

Backed by EK's reputation for quality craftsmanship, this chain uses quad staked riveting along with an oversized 5.08mm pin and 2mm plate construction to achieve an impressive 8,000 lb tensile strength rating, giving riders confidence that their drivetrain can handle the stress of everyday riding without sacrificing performance or longevity.
