At DMG Motorsports, we present the RK Excel 525XRE-120 Drive Chain — a 525-pitch, 120-link high-performance chain engineered for riders who demand serious strength without extra weight. As the next generation in RK's acclaimed chain lineup, this 525XRE model is built to replace the popular XSO series with meaningful gains in durability and wear resistance, making it an excellent OE replacement or performance upgrade for mid-size to large displacement street and off-road motorcycles.

The 525XRE is engineered around RK's advanced XW-sealing ring technology. These seals create dual lubrication pools that guard against high-speed abrasion while keeping dirt and debris from penetrating the chain's inner rollers and bushings, which translates directly into a longer service life and less frequent maintenance for your bike. Compared to the outgoing XSO series, RK engineered the XRE line to deliver a full 20% increase in wear life, all while balancing high tensile strength with a lightweight design that won't drag down acceleration or handling.

Rated for street and off-road machines up to 1000cc and 200 horsepower, this chain is a versatile fit for a wide range of sportbikes, standards, and dual-sport platforms. It ships with a rivet-style masterlink for a secure, permanent connection, giving you the confidence of OEM-level reliability whether you're commuting, touring, or pushing hard on track days. Pick up your RK Excel 525XRE-120 chain from DMG Motorsports today and keep your power delivery smooth, consistent, and built to last.
