Vortex 144AZGV4-46 Aluminum Rear Sprocket 46-Tooth

The Vortex 144AZGV4-46 is a 46-tooth aluminum rear sprocket engineered for performance-minded riders who demand lightweight, precise power transfer. Machined from high-grade 7075 aluminum alloy and finished with a hard anodized coating, this sprocket delivers an excellent strength-to-weight ratio over stock steel alternatives.

Key Features:

• 46-Tooth count for tunable acceleration and drive ratio
• 7075 aluminum construction — significantly lighter than OEM steel sprockets
• Hard anodized finish for improved corrosion resistance and surface hardness
• CNC machined for precise tolerances and consistent chain engagement
• Direct OEM replacement fitment — no modifications required
• Part of Vortex's trusted VTX series performance sprocket lineup

Vortex sprockets are a popular upgrade for sport bike and track riders looking to fine-tune gearing. Reducing sprocket tooth count raises top speed, while increasing tooth count (as with this 46-tooth unit) improves low-end torque and acceleration response. The aluminum construction saves rotating mass compared to a stock steel sprocket, contributing to quicker throttle response and reduced drivetrain load.
