Vortex 527ZR-45 CAT5 Red 45-Tooth 530-Pitch Rear Aluminum Sprocket

The Vortex 527ZR-45 is a CAT5 series 45-tooth, 530-pitch rear sprocket finished in red anodize. Machined from lightweight aerospace-grade aluminum, it delivers a significant weight reduction over OEM steel sprockets, reducing rotating mass for improved acceleration and throttle response.

Key Features:

• Lightweight 7075-T6 aluminum construction — high-grade alloy chosen for the optimal balance of strength and low weight
• 100% CNC manufactured in the U.S.A. to the tightest tolerances, ensuring a perfectly concentric sprocket every time
• Saber tooth groove design — Vortex's patented tooth profile reduces friction and drag while increasing sprocket longevity
• Color anodized finish — striking red anodize applied to the body while sweeps, mud grooves, and teeth retain a contrasting silver machined finish
• 530 chain pitch — compatible with standard 530-pitch drive chains
• 45 teeth — provides gearing adjustment versus stock for tuned acceleration or top-speed characteristics
• Reduced rotating mass multiplies power delivery and improves overall drivetrain efficiency

The Vortex CAT5 sprocket line is a proven choice for street and track riders seeking a high-performance, visually distinctive upgrade from the factory steel rear sprocket.
