The Vortex 245ZK-38 is a 38-tooth aluminum rear sprocket finished in a black anodized coating, part of Vortex's precision-engineered 245 series designed for 520 pitch chain applications. Built for performance-oriented street and track riders, this sprocket delivers an ideal balance of lightweight construction and durability.

Key Features:

• 7075-T6 billet aluminum construction — lightweight design reduces rotating mass for improved throttle response and handling
• Black anodized finish — corrosion-resistant hardcoat with a clean, aggressive appearance
• 38-tooth rear sprocket — allows fine-tuning of final drive gear ratio for acceleration or top-speed optimization
• 520 pitch chain compatibility — designed for use with 520 series drive chains
• 100% CNC machined in the USA — manufactured to tight tolerances for precise fitment and consistent performance
• Vortex patented tooth design — engineered for extended sprocket life and smooth chain engagement
• Improved acceleration and deceleration — reduced rotational mass contributes to faster directional changes and more responsive power delivery
