At DMG Motorsports, we present the Vortex CAT5 Rear Sprocket in 33T-420 Black (part #206ZK-33) — a lightweight, race-proven upgrade for compatible Honda models. Vortex sprockets are built for riders who demand less rotating mass and more confidence-inspiring performance, and the CAT5 series delivers exactly that with its signature colored-and-machined look combined with genuine racing pedigree. This sprocket is anodized first and then precision CNC machined, so you get a striking black finish set off by bright silver highlights on the machined surfaces, giving your bike a sharp, race-ready appearance that still performs when the throttle is pinned.
Machined from 7075 aluminum, this CAT5 sprocket is significantly lighter than a stock steel sprocket, which helps reduce rotating mass for quicker acceleration and sharper handling. Vortex's patented tooth design isn't just for looks — the saber tooth grooves are engineered to increase sprocket longevity while maintaining tight tolerances that racers rely on. It's no surprise that Vortex components are trusted by champions across motocross, road racing, and flat track disciplines.
