At DMG Motorsports, we present the Vortex CAT5 Rear Sprocket in 43-Tooth, 530 pitch, Black — part number 438ZK-43 — a race-proven aluminum sprocket built for Kawasaki, Suzuki, and Yamaha applications. Vortex has long been a benchmark in the sprocket world, and the CAT5 series continues that legacy by combining a striking anodized finish with the kind of precision machining that riders and racers rely on when performance and looks both matter. Swapping to this lightweight aluminum sprocket helps reduce rotating mass compared to a bulky OEM steel unit, which can translate into snappier acceleration and sharper handling on the street or the track.

Each CAT5 sprocket starts life as a raw aluminum blank that is anodized in color first, then CNC machined afterward — a process that exposes bright silver highlights across the machined surfaces while leaving the deep black anodizing intact elsewhere. The result is a distinctive, trick-looking sprocket that stands out even when the bike isn't moving. Beyond the looks, Vortex backs this sprocket with a unique tooth design engineered to increase durability and sprocket longevity, all held to the tight manufacturing tolerances that have made Vortex a trusted name among racing champions.
