The Vortex 526AZUV4-45 is a CAT5 aluminum rear sprocket featuring a 520 chain pitch and 45-tooth count. Designed for performance-oriented riders, this sprocket delivers a significant weight reduction over OEM steel units, reducing rotating mass and improving throttle response and acceleration.

Key Features:

• Lightweight CAT5 aluminum construction — reduces rotating mass for improved performance
• 100% CNC manufactured in the U.S.A. — machined to the tightest tolerances
• Specially formulated alloy per Vortex specifications for optimal strength-to-weight ratio
• Saber tooth grooves — unique tooth design engineered to increase sprocket longevity
• Vortex patented sprocket design — unlike any other sprocket on the market
• Color anodized finish with contrasting silver machined highlights on sweeps, mud grooves, and teeth excluded from anodizing
• 520 chain pitch — compatible with 520 OEM replacements or suitable 520 conversions
• 45 teeth

The Vortex CAT5 line is CNC manufactured to tight tolerances with color anodizing that excludes the sweeps, mud grooves, and teeth, resulting in vivid color accents with bright silver highlights. This sprocket is an ideal upgrade for street and track use where reducing unsprung and rotating weight translates directly to improved handling and acceleration.
