Vortex 193AZK-54 CAT5 Aluminum Rear Sprocket 520 54T Black

The Vortex 193AZK-54 is a CAT5 series rear sprocket featuring 54 teeth, designed for 520-pitch chain applications. Machined from aerospace-grade 7075 aluminum alloy and manufactured 100% CNC in the U.S.A., this sprocket delivers a significant weight reduction over OEM steel units without sacrificing durability or performance.

Vortex's CAT5 line uses a color anodizing process applied to the body of the sprocket — excluding the sweeps, mud grooves, and teeth — producing a bold black finish with contrasting bright silver machine-cut highlights. The result is a race-inspired look that holds up under hard riding conditions.

Key Features:

• 54-Tooth / 520 Pitch — high tooth count for optimized final drive gearing
• Lightweight CAT5 aluminum construction — aerospace-grade 7075-T6 alloy per Vortex specifications
• 100% CNC manufactured in the U.S.A. — tight tolerances for precise chain engagement

• Black anodized finish — color anodizing with silver machine-cut contrasts for a premium appearance
• Direct OEM replacement fit — bolt-on installation with no modification required

The Vortex CAT5 sprocket is a trusted upgrade for riders seeking reduced unsprung weight and improved drivetrain response over standard steel sprockets.
