At DMG Motorsports, we present the Vortex CAT5 Rear Sprocket in Blue, 41-Tooth, 520 pitch (452AZB-41) — a race-bred aluminum sprocket built for Kawasaki riders who want less rotating mass and more style without sacrificing durability. Vortex has built a reputation among racers for sprockets that look as good as they perform, and this CAT5 model delivers exactly that with a striking blue-anodized finish and bright silver machined highlights that make it stand out on any wheel.

Each sprocket in the CAT5 line is anodized in color first and then precision CNC machined from 7075 aluminum, so the color is locked into the material before the teeth, sweeps, and mud grooves are cut, revealing crisp silver highlights against the vivid blue background. The result is a lightweight, aerospace-grade aluminum sprocket that sheds unsprung and rotating weight compared to a heavier OEM steel sprocket, helping improve acceleration and handling. Vortex backs this design with a patented tooth profile trusted by champions on the track, engineered for long-lasting performance under hard use.
