Vortex 255A-64 Silver Aluminum Rear Sprocket 64-Tooth

The Vortex 255A-64 is a 64-tooth aluminum rear sprocket engineered for motorcycle racing and performance street applications. Manufactured entirely in the USA, this sprocket is precision CNC-machined from a specially formulated aerospace-grade aluminum alloy for an optimal balance of strength and weight savings.

Key Features:

• 64-Tooth Count — Ideal for tuning final drive ratio for improved low-end acceleration and torque
• 100% CNC Manufactured in the USA — Precision machining ensures consistent fit and performance
• Aerospace-Grade Aluminum Construction — Reduces rotational mass for improved throttle response and rear-wheel power output
• Silver Anodized Finish — Clear-coated anodized surface protects against corrosion and oxidation
• Patented Vortex Tooth Design — Unique profile unlike any other sprocket on the market, engineered to extend sprocket longevity
• Optimal Power Transfer — Delivers efficient chain engagement with reduced drivetrain friction loss

The 255A-64 is part of Vortex Racing's industry-leading rear sprocket lineup, trusted by racers and performance riders worldwide. Changing to a higher tooth-count rear sprocket increases the final drive ratio, delivering stronger bottom-end acceleration — a popular upgrade for riders seeking more aggressive performance from their motorcycle's drivetrain.
