Product Details

The Vortex 317ZKV4-42 is a high-performance 42-tooth aluminum rear sprocket from Vortex's VTX series, engineered for serious street and track riders demanding lightweight, precise power delivery. Machined from high-strength aluminum alloy and hard anodized for superior wear resistance, this sprocket delivers a significant weight savings over OEM steel alternatives without sacrificing durability.

Key Features:

  • 42-Tooth rear sprocket for optimized gear ratio tuning
  • Machined from high-strength aluminum alloy for maximum strength-to-weight ratio
  • Hard anodized finish for enhanced surface hardness and corrosion resistance
  • Precision CNC machined for accurate tooth profile and chain engagement
  • Lightweight construction reduces unsprung and rotating mass
  • Direct OEM-style fitment — no modifications required
  • Compatible with standard O-ring, X-ring, and Z-ring chains

The Vortex VTX rear sprocket is a popular upgrade for riders looking to fine-tune acceleration and throttle response. Whether used for commuting, sport riding, or track days, the 317ZKV4-42 offers a reliable, race-proven alternative to stock sprockets.
