At DMG Motorsports, we present the RK Excel GB520XRE-160 Gold 520 XW-Ring Drive Chain — a 160-link, premium performance chain built for riders who demand a perfect blend of strength, low weight, and long-term durability. As the successor to RK's proven XSO lineup, the XRE series was engineered to deliver noticeably longer service life without sacrificing the light weight that keeps your drivetrain feeling responsive. This gold-finished chain is an excellent OE-style replacement for middle-to-large displacement street and off-road machines, giving your bike a fresh, high-quality connection between engine and wheel.

Engineered with RK's advanced XW-sealing ring technology, this chain locks in lubrication and locks out the elements. The dual lubrication pools formed by the XW-rings help guard against high-speed abrasion while keeping dirt and debris from working their way into the rollers and bushings, so you get consistent performance whether you're carving corners on pavement or tackling rough trails.
