At DMG Motorsports, we present the Vortex CAT5 Rear Sprocket (454ZK-43) — a 43-tooth, 525-pitch black aluminum sprocket built for Kawasaki ZX-10R riders who demand race-proven durability without sacrificing style. This sprocket is part of Vortex's renowned CAT5 lineup, a design trusted by champions on the track and street alike. Instead of settling for an ordinary stamped-steel sprocket, upgrade to a lightweight, precision-engineered component that helps reduce rotating mass while standing out with a bold, anodized finish.

Every CAT5 sprocket starts life as premium 7075 aluminum that is anodized in color first, then CNC machined, revealing bright silver highlights against the black finish for a truly distinctive look. Beyond aesthetics, Vortex backs this sprocket with a patented tooth design engineered to increase longevity and keep your drivetrain performing lap after lap. Whether you're chasing lap times at the track or simply want a dependable, good-looking upgrade for the street, this sprocket delivers the fit, finish, and performance Vortex is known for.
