At DMG Motorsports, we present the Vortex CAT5 Rear Sprocket in Black - 41 Tooth, 525 Pitch (454ZK-41), a race-bred aluminum sprocket built for Kawasaki riders who demand less rotating mass and more confidence in the corners. Vortex has long been a favorite among racers and track-day riders alike, and this CAT5 sprocket carries on that reputation with a striking black finish, precision manufacturing, and a design engineered to hold up to serious abuse without sacrificing style.

Unlike bolt-on colored sprockets that simply coat the surface, Vortex anodizes each CAT5 sprocket in color first and then CNC machines it from premium 7075 aluminum, exposing bright silver highlights across the machined surfaces for a genuinely trick look that won't wear off like a cheap coating. Paired with Vortex's patented tooth geometry, this sprocket is designed to deliver both longevity and consistent power transfer, making it a smart upgrade over a stock steel sprocket for anyone chasing lighter unsprung weight and sharper acceleration.
