At DMG Motorsports, we present the Vortex CAT5 Rear Sprocket, Aluminum 45T-520 in Blue (part number 435ZB-45) — a lightweight, race-proven upgrade built for riders who demand both performance and style. Designed to replace heavy OEM steel sprockets, this Vortex CAT5 sprocket sheds unnecessary rotating mass, helping your bike accelerate and handle sharper on the street or the track. Compatible with a wide range of Kawasaki, Suzuki, and Yamaha models, it's the kind of upgrade that racers and enthusiasts alike trust to deliver a noticeable edge.

Vortex builds every CAT5 sprocket with a unique manufacturing process that sets it apart from ordinary aftermarket sprockets. The sprocket is anodized in color first, then CNC machined from 7075 aluminum, which strips away color from the sweeps, mud grooves, and teeth to reveal a striking two-tone finish — vivid blue with bright silver highlights that look fast even sitting still. Beyond looks, the CAT5's saber tooth grooves and unique tooth design are engineered to increase sprocket longevity, giving you a part that performs as good as it looks, ride after ride.

Manufactured 100% in the USA to tight tolerances using a specially formulated alloy per Vortex specifications, this sprocket reflects Vortex Racing's decades of experience building components trusted by top professional race teams and champions across Motocross, Supercross, Road Racing, and Flat Track disciplines. Pick up the DMG Motorsports Vortex 435ZB-45 today and give your bike a lighter, stronger, and better-looking drivetrain component.
