Vortex 452AZB-40 CAT5 Rear Aluminum Sprocket 520 Pitch 40-Tooth Blue

The Vortex 452AZB-40 is a CAT5 rear aluminum sprocket featuring a 520 chain pitch and 40 teeth, finished in a striking blue anodize with contrasting silver machine cuts. Designed for sport and street motorcycle riders who want to reduce unsprung weight without sacrificing durability, this sprocket is a direct upgrade over heavy OEM steel units.

Key Features:

• Lightweight CAT5 aluminum construction — machined from aerospace-grade aluminum, significantly lighter than OEM steel sprockets
• 100% CNC manufactured in the U.S.A. to the tightest tolerances for precise fit and reliable performance
• Specially formulated alloy per Vortex proprietary specifications for optimal strength-to-weight ratio
• Vortex patented saber tooth groove design — unique tooth profile increases sprocket longevity and chain engagement
• Color anodized finish — blue anodizing is applied to the body while excluding the sweeps, mud grooves, and teeth, delivering a bold color pop with bright silver highlights
• 520 pitch, 40-tooth rear sprocket configuration
• Available in four colors (red, blue, gold, and black) with contrasting silver machine cuts

The Vortex CAT5 sprocket line is engineered for riders who demand race-proven quality on the street or track. The patented design is unlike any other sprocket on the market, combining eye-catching aesthetics with the functional performance benefits of a premium aluminum drivetrain component.
