Vortex 780ZL-38 Aluminum Rear Sprocket 38-Tooth Silver

The Vortex 780ZL-38 is a 38-tooth aluminum rear sprocket engineered for performance-focused motorcycle riders who demand reduced rotating mass and improved drivetrain efficiency. Manufactured 100% in the USA, this sprocket is CNC-machined from a specially formulated aerospace-grade aluminum alloy per Vortex's own specifications, delivering an ideal balance of lightweight construction and durability.

Key Features:

• 100% CNC manufactured in the USA for precise tolerances and consistent quality
• Aerospace-grade aluminum alloy — specially formulated to Vortex specifications for optimal strength-to-weight ratio
• Silver (clear) anodized finish applied to help prevent oxidation and corrosion
• Vortex patented sprocket tooth design unlike any other sprocket on the market
• Unique tooth geometry engineered to increase sprocket longevity and reduce chain wear
• 38 teeth for precise gear ratio tuning
• Significantly lighter than OEM steel sprockets, reducing rotating mass for improved acceleration and handling

Vortex aluminum sprockets are popular with road racers, track day enthusiasts, and performance street riders. Because aluminum sprockets are more sensitive to chain condition than steel, chain cleaning and tension should be checked every 300–600 miles on street bikes to maximize service life. The iconic two-tone machined look is achieved by applying the finish before the sprocket teeth are cut.
