Key Features:

• 45-Tooth Configuration – Provides increased low-end acceleration and torque delivery compared to stock gearing
• Lightweight Aluminum Construction – CNC-machined from high-strength aluminum alloy to reduce unsprung and rotating weight
• VTX Series Design – Features Vortex's signature hard-anodized finish for improved corrosion resistance and durability
• Precision CNC Machined – Tight tolerances ensure smooth chain engagement and consistent power transfer

Upgrading to the Vortex VTX aluminum rear sprocket is a popular modification for riders looking to fine-tune their gearing for the track or street. The reduced weight compared to a steel sprocket helps lower rotational mass, contributing to quicker throttle response. The hard-anodized aluminum finish resists wear and corrosion under demanding riding conditions.
