At DMG Motorsports, we present the Vortex CAT5 Aluminum Rear Sprocket, 45T-530 in Silver (Part# 436-45), built for select Kawasaki and Suzuki sportbikes. Recognized as the standard in the race industry, this sprocket is engineered to shed unnecessary rotating mass while standing up to the demands of serious track and street riding. Vortex sprockets are trusted by champions because they deliver the tight tolerances, precision fitment, and consistent performance that racers rely on when every ounce and every tooth matters.

Each CAT5 sprocket is CNC machined from 7075 aluminum, a material chosen for its exceptional strength-to-weight ratio, then finished with an anodized silver coating that gives the sprocket a striking, race-ready appearance. Because an aluminum sprocket weighs significantly less than a comparable OEM steel unit, swapping to this Vortex CAT5 sprocket reduces rotating mass at the rear wheel, which translates into snappier acceleration and sharper handling response — the same benefits that have made Vortex sprockets a go-to choice among professional racers and serious enthusiasts alike.

Beyond the weight savings, Vortex backs this sprocket with a unique tooth design and tight manufacturing tolerances that help ensure smooth chain engagement and long-term durability under hard use. Whether you're chasing lap times or simply want a lighter, better-looking replacement for your stock sprocket, this 45-tooth, 530-pitch Vortex sprocket is ready to bolt on and perform.
