At DMG Motorsports, we present the EK Chain 520SR Non-Sealed 100-Link Drive Chain (520SR-100) — a heavy-duty, general purpose chain engineered for riders who demand durability without paying for features they don't need. Built as the beefed-up version of EK's Sport Chain line, the 520SR is purpose-built for lower horsepower dirt, ATV, and street applications where a non-sealed design still needs to deliver serious strength and long-term wear resistance. Solid bushings, solid rollers, and EK's special steel alloy construction combine with quad-point staked riveting to give this chain the muscle to handle demanding conditions ride after ride, all while keeping cost in check. Whether you're refreshing worn-out drivetrain components or building a fresh setup, the EK 520SR-100 gives you a trusted, race-proven brand backing a chain that just works.

Features:

• Heavy-duty version of EK's Sport Chain, built for lower horsepower dirt, ATV, and street applications
