At DMG Motorsports, we present the Vortex CAT5 Rear Sprocket, Aluminum 46T-520 in Black for Kawasaki applications (452AZK-46) — a race-bred sprocket built for riders who demand less weight, more style, and championship-proven durability. Vortex anodizes the sprocket first and then CNC machines it from premium 7075 aircraft-grade aluminum, so the finished piece shows off a bold black finish contrasted by bright silver machined highlights. This isn't just about looks: shedding rotating mass at the rear wheel is one of the most effective ways to sharpen acceleration and handling, and Vortex has been refining this formula for competition since 1995.

The CAT5 design incorporates Vortex's patented saber tooth grooves, a unique tooth profile engineered to extend sprocket life and deliver smoother, more efficient power transfer to the rear wheel. Every sprocket is 100% CNC manufactured in the U.S.A. to tight tolerances from a specially formulated alloy, ensuring precise fitment and consistent performance whether you're carving up the street or putting down laps at the track. It's the kind of hardware that's earned Vortex's reputation as a brand trusted by champions.
