Vortex 144AZR-42 Aluminum Rear Sprocket 42-Tooth

The Vortex 144AZR-42 is a high-performance aluminum rear sprocket designed for motorcycle racing and performance applications. This 42-tooth sprocket combines lightweight construction with race-proven durability to deliver superior performance on the track or street.

Key Features:

• 42-tooth configuration for optimized gearing
• Constructed from aerospace-grade 7075-T6 aluminum alloy for maximum strength-to-weight ratio
• 100% CNC machined in the USA to precise tolerances
• Features Vortex's patented saber tooth groove design for increased sprocket longevity
• Anodized finish provides corrosion resistance and distinctive appearance
• Lightweight design reduces rotating mass for improved acceleration and handling
• Precision-engineered to maintain concentricity and reduce chain wear

Vortex aluminum sprockets are significantly lighter than OEM steel sprockets, reducing unsprung weight and allowing more power to reach the pavement. The advanced CNC machining process ensures perfect roundness and tooth profile accuracy, resulting in smoother operation and extended chain life. Each sprocket is manufactured to strict quality standards used in professional racing applications.
