At DMG Motorsports, we present the Vortex CAT5 Rear Sprocket 45T-530 in Black (438ZK-45) — a race-proven aluminum sprocket built for riders who demand performance without sacrificing style. Fitting select Kawasaki, Suzuki, and Yamaha models running a 530 chain conversion, this sprocket combines Vortex's signature manufacturing process with a striking black finish and bright silver highlights that make it look as fast as it performs. Vortex sprockets are anodized first and then precision CNC machined from 7075 aluminum, so the color anodizing is cut away at the sweeps, mud grooves, and teeth, revealing a flash of color set against silver machined accents for a truly trick look.

Beyond the aggressive aesthetics, this sprocket is engineered for real performance gains. Its lightweight aluminum construction sheds unnecessary rotating mass compared to bulky OEM steel sprockets, helping improve acceleration and handling every time you twist the throttle. The unique CAT5 tooth design isn't just for show — it's engineered to increase sprocket longevity, so you get lasting durability along with the reduced weight. It's no surprise this sprocket has earned the trust of champions on the track.
