Vortex 720FZK-49 Aluminum Rear Sprocket 49 Tooth

The Vortex 720FZK-49 is a high-performance aluminum rear sprocket designed for sportbike and racing applications. Precision-machined from aerospace-grade 7075-T6 aluminum alloy, this lightweight sprocket delivers exceptional strength-to-weight ratio while reducing unsprung weight for improved handling and acceleration.

Key Features:

• 49-tooth configuration for optimized gearing
• 7075-T6 aircraft-grade aluminum construction for maximum durability
• CNC-machined for precise tolerances and perfect chain alignment
• Hard-anodized finish for superior wear resistance and corrosion protection
• Self-cleaning mud grooves prevent debris buildup
• Lightening holes reduce rotating mass without sacrificing strength
• Direct OEM replacement for easy installation

Vortex sprockets are manufactured to exacting standards and undergo rigorous quality control testing. The hard anodizing process creates a surface that is significantly harder than the base aluminum, extending service life while maintaining the weight advantage over steel sprockets. This sprocket is ideal for riders seeking performance upgrades, custom gearing ratios, or reliable OEM replacement components.
