Vortex 144AZKV4-41 CAT5 Aluminum Rear Sprocket 41-Tooth Silver Anodized

The Vortex 144AZKV4-41 is a lightweight CAT5 aluminum rear sprocket featuring a 41-tooth configuration and a silver anodized finish. Engineered by Vortex Racing in the USA, this sprocket is built to deliver real performance gains over the stock steel unit by significantly reducing rotating mass in the drivetrain.

Key Features:

• CAT5 Aluminum Construction: Manufactured from a specially formulated alloy per Vortex specifications for an optimal balance of strength and weight savings
• 100% CNC Machined in the USA: Precision CNC manufacturing ensures a perfectly concentric sprocket and tight tolerances every time
• Silver Anodized Finish: Anodized coating provides corrosion resistance and a clean, polished appearance
• Patented Tooth Design: Vortex's unique, patented tooth geometry reduces drag and friction while extending sprocket and chain life
• Reduced Rotating Mass: Lighter drivetrain components improve throttle response and acceleration
• 41 Teeth: Direct replacement or performance upgrade tooth count for compatible applications

Vortex Racing rear sprockets are a trusted choice among street riders and racers alike. By replacing a heavier OEM steel sprocket with this aluminum unit, riders benefit from improved power delivery and sharper throttle response. Always pair with a matching pitch chain and front sprocket for optimal performance and longevity.
