Product Details

The Vortex 920ZK-45 is a lightweight, high-performance aluminum rear sprocket from Vortex's VTX series, engineered for riders who demand precision and durability. Machined from aircraft-grade 7075-T6 aluminum, this sprocket offers a significant weight savings over stock steel sprockets without sacrificing strength or longevity.

Key Features:

  • 45-Tooth count for optimized acceleration and gear ratio tuning
  • 520 chain pitch compatibility for a wide range of sport and street motorcycles
  • Aircraft-grade 7075-T6 aluminum construction for maximum strength-to-weight ratio
  • Hard anodized finish for corrosion resistance and extended wear life
  • CNC machined to tight tolerances for precise fitment and smooth chain engagement
  • Lightweight design reduces unsprung and rotating mass for improved throttle response
  • Direct OEM-style bolt pattern for straightforward installation

The Vortex VTX aluminum rear sprocket is a popular upgrade for sport bike enthusiasts looking to fine-tune their drivetrain gearing. Whether optimizing for track performance or street riding, the 920ZK-45 delivers a reliable, race-proven alternative to the factory sprocket.

Shopping at checkout was really easy, but I haven't installed the product yet so I can't give a proper review

Good price, Quick turn around

great delivery time, fair price

Great prices and exceptional delivery, think the order was delivered before I clicked submit ;)

It was delivered when it said it was supposed to haven't opened it yet but look forward to seeing it

It was a hard-to-find item that Boatplicity had in stock and at a decent price. I will be back for more stuff for my boat.

Ordered a GE RV AC. Received it quickly in good condition.
