At DMG Motorsports, we present the EK Chain SPORT Non-Sealed 520-90L (SKU: 69-3790) — a dependable, no-frills drive chain built for riders who want a meaningful upgrade over their factory chain without paying for features they don't need. Designed specifically for lower horsepower dirt, ATV, and street applications, this 520 pitch chain delivers the fit, finish, and reliability EK has been known for since the company's founding, all packaged in an affordable, long-lasting non-sealed design. Whether you're refreshing worn-out OEM equipment or building up a budget-friendly ride, this chain gets the job done without unnecessary drag or bulk.

EK Chain has built a reputation over decades as one of the most trusted names in drive chain manufacturing, and this SPORT series non-sealed chain reflects that legacy in an economical package.
