Vortex 422-64 Silver 64-Tooth 428-Pitch Aluminum Rear Sprocket

The Vortex 422-64 is a 64-tooth, 428-pitch aluminum rear sprocket designed as a high-performance replacement or gearing upgrade for compatible motorcycles. Machined from lightweight aluminum and finished in a classic silver anodized coating, this sprocket delivers a meaningful weight reduction over OEM steel units, helping reduce rotating mass for improved throttle response and acceleration.

Vortex sprockets are manufactured in the USA to strict tolerances, featuring a patented tooth profile engineered for improved chain engagement, reduced wear, and extended service life. The silver clear-coat anodized finish provides corrosion resistance and a clean, polished appearance.

Key Features:

• 64 teeth — high-ratio rear sprocket for enhanced low-end torque and acceleration
• 428 chain pitch — must be paired with a matching 428-pitch chain and front sprocket
• Lightweight aluminum construction — significantly lighter than OEM steel sprockets
• 100% CNC-machined to tight tolerances for precise fitment and concentricity
• Silver anodized finish — clear-coat protection for long-lasting appearance and corrosion resistance
• Vortex patented tooth design for improved chain engagement and sprocket longevity
• Weight-saving cutouts reduce overall rotating mass

When changing rear sprocket tooth count, adding teeth increases low-end torque and acceleration while reducing top speed; removing teeth has the opposite effect. Always replace the chain and front sprocket together when installing a new rear sprocket to ensure even wear and proper fitment.
