At DMG Motorsports, we present the Vortex CAT5 Rear Sprocket 45T-530 in Black (527ZK-45) — a race-proven, aluminum rear sprocket built for Suzuki and Triumph platforms that demand both performance and style. Vortex sprockets are anodized in color first, then CNC machined from 7075 aluminum, a reverse-order process that leaves the sweeps, mud grooves, and teeth in brilliant silver while the rest of the sprocket stays bathed in deep black anodizing. The result is a "trick colored sprocket with silver highlights" that stands out on the swingarm as much as it performs on the track or street.

Built to Vortex's own specially formulated alloy specifications and 100% CNC manufactured in the USA, this CAT5 sprocket is machined to tight tolerances for precise chain engagement and smooth power delivery. Its unique tooth design, featuring Vortex's signature saber tooth grooves, is engineered to increase sprocket longevity, while the lightweight aluminum construction sheds rotating mass compared to a heavier OEM steel sprocket, helping improve acceleration and handling. Riders and racers alike trust Vortex CAT5 sprockets because the patented design is unlike anything else on the market — this is gearing that's genuinely trusted by champions.
