• Precision CNC-machined from high-grade aluminum alloy for reduced weight
• Part of Vortex's VTX series — engineered for performance street and track use
• Hard-anodized finish for enhanced wear resistance and corrosion protection

Vortex Racing is a trusted name in performance drivetrain components, known for producing sprockets that meet or exceed OEM tolerances. The 254ZK-37 is an ideal upgrade for riders looking to fine-tune their gearing for either more top-end speed or improved low-end torque response. Always replace the sprocket in conjunction with a new chain for optimal drivetrain life and performance.
