Vortex 254-46 Aluminum Rear Sprocket 46-Tooth

The Vortex 254-46 is a lightweight 46-tooth aluminum rear sprocket engineered for high-performance motorcycle applications. Built on Vortex Racing's proven CAT5 platform, this sprocket delivers a significant weight reduction over stock steel alternatives, helping reduce rotating mass and improve throttle response.

Key Features:

• Lightweight aluminum construction — significantly reduces rotating mass compared to steel sprockets for improved acceleration and deceleration response
• 100% CNC manufactured in the USA — precision-machined to exact tolerances for consistent fit and performance
• Specially formulated alloy per Vortex specifications for optimal strength-to-weight ratio
• Silver anodized finish — helps prevent corrosion and oxidation for extended service life
• Vortex patented CAT5 tooth design — saber tooth grooves increase sprocket longevity and reduce chain wear
• 46 teeth — allows fine-tuning of final drive gearing for improved low-end torque and acceleration

Vortex Racing aluminum sprockets are the preferred choice for road racing, track days, and performance street riding. As with all aluminum rear sprockets, regular chain maintenance — cleaning and proper tensioning every 300–400 miles — is recommended to maximize service life. The 254-46 is a direct bolt-on replacement designed for specific motorcycle applications.
