Vortex 427ZK-43 Aluminum Rear Sprocket 43-Tooth 530-Pitch Black with Silver Machined Accents

The Vortex 427ZK-43 is a 43-tooth, 530-pitch aluminum rear sprocket featuring a striking black anodized finish with contrasting silver machine-cut accents. Designed for the Kawasaki ZX-14 (all years), this sprocket is a direct-fit, high-performance upgrade over the heavy OEM steel unit.

Engineered and manufactured entirely in the USA, Vortex sprockets are crafted from a specially formulated aluminum alloy to deliver an exceptional balance of strength and low weight. Reduced rotating mass translates directly to improved throttle response and acceleration, making this an ideal upgrade for both street and track use.

Key Features:

• 43 teeth, 530 pitch — direct replacement sizing for compatible applications
• Black anodized finish with contrasting silver machined accents for a distinctive appearance
• Lightweight aluminum construction reduces rotating mass for improved performance
• 100% CNC manufactured in the USA to the tightest tolerances
• Specially formulated alloy per Vortex specifications for optimal strength-to-weight ratio
• Vortex patented saber-tooth groove design increases sprocket longevity and reduces chain wear
• Perfectly concentric CNC machining frees horsepower and extends the life of both chain and sprocket
