At DMG Motorsports, we present the Vortex CAT5 Rear Sprocket in Aluminum, 42T-525 pitch, finished in eye-catching Blue and built to fit select Kawasaki, Suzuki, and Yamaha models. This isn't just another replacement sprocket — it's a race-proven upgrade designed to shed rotating mass while adding a serious dose of style to your drivetrain. Vortex has spent decades supplying components to championship-winning teams, and this CAT5 sprocket brings that same track-tested engineering straight to your bike.

Unlike sprockets that are dyed after machining, Vortex anodizes the CAT5 series first and then CNC machines it from premium 7075 aluminum, so the finished piece reveals bright silver highlights around the anodized blue surface for a truly distinctive, "trick" look that OEM steel sprockets simply can't match. Beyond aesthetics, the lightweight aluminum construction reduces rotating mass compared to a stock steel sprocket, helping improve acceleration and handling, while the unique tooth design is engineered for smoother power transfer and extended service life under demanding riding conditions.

• CNC machined from premium 7075 aluminum for a strong, lightweight sprocket
