Vortex 245AZGV4-42 VTX Aluminum Rear Sprocket 42T

The Vortex 245AZGV4-42 is a high-performance 42-tooth aluminum rear sprocket from Vortex Racing's VTX series. Precision-machined from lightweight 7075-T6 aluminum, this sprocket delivers an excellent balance of strength and weight reduction compared to steel OEM units — a popular upgrade for sport and street riders looking to improve throttle response and reduce unsprung rotating mass.

Vortex sprockets are manufactured to exacting tolerances and feature a hard anodized finish for corrosion resistance and long service life. The VTX carrier design integrates the sprocket and carrier hub into a single lightweight assembly, simplifying installation and reducing overall drivetrain weight.

Key Features:

• 42 teeth — optimized gearing for acceleration or top-speed tuning depending on application
• Machined from 7075-T6 aluminum for an ideal strength-to-weight ratio
• Hard anodized finish for durability and corrosion resistance
• VTX integrated carrier design for easy bolt-on installation
• Precision CNC-machined for consistent chain engagement and smooth power delivery
• Manufactured by Vortex Racing, a trusted name in performance drivetrain components

A direct bolt-on upgrade over the stock rear sprocket, the Vortex VTX aluminum sprocket is an ideal choice for riders seeking to fine-tune their gearing while shedding weight from the drivetrain.
