At DMG Motorsports, we present the Vortex CAT5 Rear Sprocket 42T-530 in Black (P/N 436ZK-42) — a race-bred aluminum sprocket built for Kawasaki and Suzuki riders who want a lighter, stronger, better-looking alternative to a bulky OEM steel sprocket. Vortex builds every CAT5 sprocket with a distinctive process: the blank is anodized first, then precision CNC machined from 7075 aluminum, so the finished sprocket shows off a bold black finish contrasted by bright silver highlights where the material is cut. It's the kind of sprocket that looks fast standing still and performs even better once you're on the throttle.

Cutting rotating mass at the rear wheel is one of the most effective ways to sharpen acceleration and handling, and swapping to this lightweight CAT5 aluminum sprocket does exactly that compared to a heavier stock steel unit. Vortex backs the look with substance: a patented, unique tooth design that increases sprocket longevity and tight manufacturing tolerances that have made these sprockets a favorite among racing champions. Whether you're chasing lap times at the track or just want a cleaner, more aggressive look on the street, this 42-tooth, 530-pitch sprocket delivers both style and performance.
