At DMG Motorsports, we present the Vortex CAT5 Rear Aluminum Sprocket in Blue — a 45-tooth, 520-pitch sprocket engineered specifically for compatible Honda applications and part number 251AZB-45. Since 1995, the CAT5 has become one of the most recognized sprocket designs in the industry, and this example brings that pedigree straight to your drivetrain. Vortex anodizes the sprocket in vivid blue before CNC machining it from 7075 aluminum, so the finished piece flashes bold color contrasted by bright, precision-cut silver highlights around the teeth and cutouts. The result is a sprocket that looks as aggressive as it performs, swapping out heavy OEM steel for a lightweight aluminum alternative that reduces rotating mass for snappier acceleration and sharper handling. Built with Vortex's patented, unique tooth design for extended wear life and manufactured to the tight tolerances that racers demand, this sprocket is trusted by champions on the track and street alike. Whether you're chasing lap times or simply want a cleaner, faster-looking rear wheel, this Vortex CAT5 sprocket delivers the style and substance to back it up.
