At DMG Motorsports, we present the RK Excel 520XRE-122 Drive Chain — a lightweight, high-performance 520 pitch chain built with 122 links for riders who demand long wear-life without sacrificing strength. As the successor to RK's proven XSO lineup, the XRE series delivers a noticeable step forward in durability and performance, making it an excellent OE-style replacement for mid-to-large displacement street and off-road motorcycles. Engineered with RK's advanced XW-sealing ring technology, this chain forms dual lubrication pools that guard against high-speed abrasion while keeping dirt and debris out of the rollers and bushings, so your drivetrain stays protected ride after ride. Whether you're tackling the track, the trail, or the street, the 520XRE-122 strikes the ideal balance between high tensile strength and reduced weight for smooth, reliable power delivery.
