Vortex 452AZKV4-46 Aluminum Rear Sprocket 46T Black Anodized

The Vortex 452AZKV4-46 is a 46-tooth aluminum rear sprocket engineered for sport bike and motorcycle applications requiring a lightweight, high-strength drivetrain upgrade. Part of Vortex's popular 452 series, this sprocket is precision CNC-machined from high-grade aluminum alloy and features a durable black anodized finish for corrosion resistance and a clean, aggressive appearance.

Vortex sprockets are manufactured to OEM tolerances and are a direct bolt-on replacement, ensuring proper chain alignment and smooth power transfer. The aluminum construction significantly reduces unsprung rotational mass compared to steel sprockets, contributing to improved throttle response and overall performance.

Key Features:

• 46 teeth — ideal for adjusting final drive ratio for acceleration or top-speed tuning
• CNC-machined 7075 aluminum construction for strength-to-weight advantage
• Black anodized finish for corrosion resistance and long-lasting aesthetics
• Precision-cut tooth profile for smooth, quiet chain engagement
• Direct OEM replacement fitment — no modification required
• Reduced unsprung weight improves throttle response vs. steel sprockets
• Manufactured by Vortex Racing, a trusted name in motorsports drivetrain components

The Vortex 452AZKV4-46 is an excellent choice for riders looking to fine-tune their gearing or replace a worn sprocket with a performance-grade component. Always replace the front sprocket and drive chain simultaneously for optimal drivetrain longevity.
