Vortex 840AZOV4-47 Aluminum Rear Sprocket 47-Tooth

The Vortex 840AZOV4-47 is a 47-tooth aluminum rear sprocket engineered for sport and street motorcycle applications. Vortex is a leading manufacturer of performance drivetrain components, and this sprocket is machined from lightweight 7075-T6 billet aluminum for an optimal balance of strength and weight savings over a stock steel sprocket.

Key Features:

• 47-Tooth Count — precise tooth count for direct OEM replacement or performance gearing adjustment
• Billet 7075-T6 Aluminum Construction — significantly lighter than steel while maintaining excellent durability
• Hard Anodized Finish — resists corrosion, wear, and chain abrasion for extended service life
• CNC Machined — precision machining ensures accurate tooth profile and consistent chain engagement
• Lightening Cutouts — strategically placed pockets reduce unsprung rotational mass for improved acceleration and handling response
• Direct Bolt-On Fitment — matches OEM bolt pattern for straightforward installation without modification

Vortex sprockets are a popular upgrade for riders looking to fine-tune their final drive gearing or reduce drivetrain weight. The 840AZOV4-47 is designed to work with the matching Vortex front sprocket and chain for a complete drivetrain solution. Always verify chain compatibility and pitch when replacing sprocket components.
