Vortex 404ZB-48 Aluminum Rear Sprocket 48-Tooth

The Vortex 404ZB-48 is a high-performance aluminum rear sprocket engineered for riders seeking reduced rotating mass and improved acceleration. This 48-tooth sprocket is precision CNC-machined from aerospace-grade 7075-T6 aluminum, the strongest aluminum alloy used in motorcycle applications, delivering an optimal balance of lightweight construction and exceptional durability.

Key Features:

• 48-tooth configuration for customizable gearing options
• CNC-machined to tightest tolerances ensuring perfect concentricity
• Constructed from 7075-T6 aluminum for maximum strength-to-weight ratio
• Black zinc finish (ZB) provides corrosion resistance and distinctive appearance
• Optimized tooth profile reduces friction and extends chain life
• Drilled lightening holes reduce rotating mass for quicker acceleration
• Compatible with 520-pitch chains (verify fitment for your specific application)

Vortex sprockets are manufactured in the USA by motorcycle racing enthusiasts and are tested by professional race teams worldwide. The reduced rotating weight compared to steel sprockets translates directly to improved throttle response and acceleration, making this an excellent upgrade for both street and track applications.
