Vortex 775A-65 Aluminum 65-Tooth 520-Pitch Rear Sprocket

The Vortex 775A-65 is a precision-engineered aluminum rear sprocket featuring 65 teeth with a 520 pitch chain compatibility. This sprocket is designed for motorcycles requiring increased acceleration and lower top-end speed compared to stock gearing.

Key Features:

• 100% CNC machined from 7075-T6 billet aluminum for exceptional strength and minimal weight
• Proprietary saber tooth groove design increases sprocket longevity and chain engagement
• 65-tooth count for optimized gear ratio adjustment
• 520 pitch chain compatibility for performance applications
• Available in multiple finish options including anodized colors and PTFE black hardcoat
• PTFE hardcoat option bonds to aluminum creating a more durable surface with reduced friction
• Lightweight construction reduces unsprung weight for improved handling

Vortex sprockets feature a unique tooth profile design that distributes load more evenly across the chain, extending the life of both the sprocket and chain. The precision CNC machining ensures perfect tooth spacing and alignment for smooth, reliable power transfer.
