Vortex 193AZB-44 Aluminum Rear Sprocket 525 Pitch 44-Tooth

The Vortex 193AZB-44 is a 44-tooth, 525-pitch aluminum rear sprocket designed for serious street and road racing applications. Machined from a specially formulated, lightweight aluminum alloy to Vortex's exacting specifications, this sprocket delivers a meaningful reduction in rotating mass compared to stock steel units — helping put more power to the pavement.

Key Features:

• 525 chain pitch — compatible with 525-series drive chains
• 44 teeth — direct replacement or gearing alternative to OEM fitment
• 100% CNC manufactured in the USA — machined to tight tolerances for precise chain engagement
• Lightweight F5 / 7075-T6 billet aluminum construction — reduces unsprung rotating mass
• Anodized finish — corrosion-resistant surface treatment for long service life
• Vortex patented saber-tooth groove design — unique tooth geometry increases sprocket longevity and chain wear
• PTFE-compatible surface — available in hardcoat black for added lubricity and durability (see related variants)

Vortex Racing has been producing competition-proven drivetrain components from their USA facility since 1995. Each sprocket is engineered and tested with direct input from professional race teams, making the 193AZB-44 equally at home on the track or the street.
