At DMG Motorsports, we present the Vortex CAT5 Rear Sprocket in Red — a 42-tooth, 520-pitch aluminum sprocket built for Kawasaki, Suzuki, and Yamaha applications (part number 435ZR-42). Vortex has built its reputation on the track, and the CAT5 series is the sprocket of choice for riders who want race-proven durability without sacrificing style. This sprocket swaps out heavy OEM steel for a lightweight aluminum alternative that reduces rotating mass, helping your bike accelerate harder and handle sharper corner to corner.

Every CAT5 sprocket starts life as raw 7075 aluminum that is anodized in color first, then precision CNC machined — a process that leaves behind a striking two-tone finish with silver highlights cut right into the red anodizing. It's not just a cosmetic upgrade: the same tight-tolerance machining and patented tooth design that make this sprocket look fast also make it last on demanding street and track applications. It's why racing champions keep coming back to Vortex.
