At DMG Motorsports, we present the Vortex CAT5 Rear Sprocket 42T-525 in Black (435CZK-42) — a race-proven upgrade built to shed unwanted rotating mass while adding a striking splash of color to your Kawasaki, Suzuki, or Yamaha. Vortex starts with the anodizing process first and then CNC machines the sprocket, cutting through the color to reveal bright silver highlights on the sweeps, mud grooves, and teeth for a trick, two-tone look that stands out on the track or the street. This is far more than a cosmetic upgrade: it's the same CAT5 design trusted by champions in professional roadracing.

Features:

• Anodized first, then CNC machined from premium 7075 aluminum for a durable, lightweight sprocket
• Reveals bright silver highlights against the black anodized finish for a distinctive, trick appearance
• Unique saber tooth design increases sprocket longevity and improves power transfer efficiency
• 100% CNC manufactured in the U.S.A. to Vortex's specially formulated alloy specifications
• Lighter than OEM steel sprockets, reducing rotating mass for improved acceleration and handling
• Vortex's patented sprocket design, trusted by champions in competitive racing
• 42-tooth count on 525 chain pitch, designed to fit select Kawasaki, Suzuki, and Yamaha models
• Part number: 435CZK-42
