Product Details

The Vortex 435KV4-39 is a 39-tooth aluminum rear sprocket designed for high-performance motorcycle applications. Engineered to Vortex Racing's exacting standards, this sprocket offers an excellent balance of lightweight construction and durability for street and track use.

Key Features:

  • Material: CNC-machined 7075-T6 aluminum alloy for superior strength-to-weight ratio
  • Tooth Count: 39 teeth
  • Chain Pitch: 435 series chain compatible
  • Finish: Hard anodized for corrosion resistance and extended wear life
  • Construction: Precision CNC machined for accurate tooth geometry and consistent chain engagement
  • Weight Savings: Significantly lighter than OEM steel sprockets, reducing unsprung rotational mass
  • Fitment: KV4 hub pattern for direct OEM replacement fitment

Vortex sprockets are a popular upgrade for riders seeking to reduce drivetrain weight and fine-tune their gearing ratio. The hard-anodized aluminum construction provides long service life while keeping weight to a minimum — ideal for sport bikes and track-day machines.
