Vortex 526AZB-44 CAT5 Rear Sprocket 520 Pitch 44-Tooth Blue Aluminum

The Vortex 526AZB-44 is a CAT5 Series aluminum rear sprocket designed for high-performance motorcycle applications. Featuring a 520 pitch and 44 teeth, this sprocket delivers a lightweight, race-proven alternative to heavy OEM steel sprockets.

Vortex's CAT5 design uses a color anodizing process applied before CNC machining, which intentionally excludes the sweeps, mud grooves, and teeth from the anodized coating. The result is a striking two-tone appearance — a vivid blue finish with bright silver machined highlights that give your drivetrain a clean, race-ready look.

Key Features:

• 520 Pitch — compatible with 520-size OEM chains or suitable 520 conversion setups
• 44 Teeth — precision tooth count for optimized gearing
• Lightweight CAT5 aluminum construction — reduces unsprung and rotational weight versus stock steel
• 100% CNC manufactured in the U.S.A. — tight tolerances for precise fit and consistent performance
• Specially formulated aluminum alloy per Vortex specifications for optimal strength-to-weight ratio
• Saber tooth groove design — unique tooth profile engineered to increase sprocket longevity
• Anodized blue finish with silver highlights — two-tone appearance from pre-cut color anodizing process
• Mud grooves and coatings help keep drivetrain components clean
• Vortex patented sprocket design

The CAT5 sprocket line has been an industry staple since its introduction in 1995, offering racers and performance street riders a proven combination of durability, weight savings, and visual appeal. Designed for 520-size OEM replacements or appropriate 520 conversions.
