At DMG Motorsports, we present the Vortex CAT5 Rear Sprocket 436ZK-40 — a 40-tooth, 530-pitch aluminum sprocket built for riders who want race-proven performance with unmistakable style. This black CAT5 sprocket is engineered to shed unnecessary rotating mass off your Kawasaki or Suzuki, sharpening acceleration and handling while giving your bike a distinct, finished look that stands out at the track or on the street.

Vortex builds every CAT5 sprocket through a unique anodize-first, machine-second process. The blank is color anodized before being precision CNC machined from premium 7075 aluminum, so the finished sprocket reveals a bold black finish contrasted by bright silver highlights where the material is cut away. The result isn't just a sprocket that looks fast standing still — it's backed by Vortex's patented tooth geometry that has earned the trust of champions across multiple racing disciplines.

Features:

• Anodized first, then CNC machined from premium 7075 aluminum for a striking black finish with contrasting silver highlights
• Lightweight aluminum construction reduces rotating mass for improved acceleration and handling versus heavier OEM steel sprockets
• Unique, patented Vortex tooth design increases sprocket longevity and delivers smooth, reliable power transfer
• 40-tooth, 530-pitch configuration designed to fit select Kawasaki and Suzuki models
• 100% CNC manufactured to tight tolerances for consistent quality and fitment
• Trusted by champions - the CAT5 series is a proven choice among racers for performance and durability
