At DMG Motorsports, we present the Vortex CAT5 Rear Sprocket 43T-520 in Black (P/N 452AZK-43) — a race-bred, lightweight aluminum sprocket built for Kawasaki riders who demand precision and performance. Vortex has spent years engineering components trusted by champions, and the CAT5 series is a shining example of that pedigree, combining aggressive style with real-world durability on the track or street.

This sprocket is anodized in color first, then CNC machined from 7075 aluminum, which cuts away the color at the sweeps, mud grooves, and teeth to reveal a striking two-tone look — a trick black finish accented with bright silver highlights. Beyond the eye-catching appearance, the CAT5's patented tooth design is engineered for increased longevity, giving you a sprocket that looks as good as it performs, mile after mile.

Features:

• Anodized first, then CNC machined from 7075 aluminum for a durable, trick-colored finish with contrasting silver highlights
• Lightweight CAT5 aluminum construction reduces rotating mass for improved acceleration and handling versus heavier OEM steel sprockets
• Unique, patented tooth design increases sprocket longevity and is unlike any other sprocket on the market
• 100% CNC manufactured to tight tolerances using a specially formulated alloy per Vortex specifications
• Proven design trusted by racing champions for its reliability and performance
• 43-tooth, 520-pitch configuration in black, designed to fit select Kawasaki models
