Vortex 720ZB-45 Aluminum Rear Sprocket 45-Tooth 520-Pitch

The Vortex 720ZB-45 is a high-performance aluminum rear sprocket engineered for sport bikes and racing applications. This 45-tooth, 520-pitch sprocket is precision CNC-machined from aerospace-grade 7075-T6 aluminum, delivering exceptional strength while reducing rotational mass for improved acceleration and handling.

Key Features:

• 45-tooth configuration for 520-pitch chain applications
• CNC-machined from lightweight 7075-T6 aluminum alloy
• Color anodized finish with zinc-plated steel bolt holes for corrosion resistance
• Precision-cut teeth with mud grooves to clear debris and extend chain life
• Manufactured to tight tolerances for optimal chain alignment and reduced wear
• Significantly lighter than OEM steel sprockets for reduced unsprung weight
• Hard-anodized coating protects against wear and the elements

Vortex sprockets are tested by professional race teams worldwide and manufactured in the USA to exacting quality standards. The 720 series features enhanced durability through advanced metallurgy and surface treatments, making these sprockets competitive with steel alternatives in terms of lifespan while maintaining the weight-saving benefits of aluminum construction.
