Product Details

The Vortex 438ZKV4-40 is a 40-tooth aluminum rear sprocket from Vortex's VTX series, engineered for performance motorcycle applications. Precision CNC-machined from lightweight aluminum, this sprocket delivers the ideal balance of reduced unsprung weight and reliable power transfer from the drivetrain to the rear wheel.

Key Features:

  • 40-tooth rear sprocket for optimized final drive gearing
  • Precision CNC-machined from high-grade aluminum for lightweight performance
  • Hard-anodized finish for enhanced durability and corrosion resistance
  • VTX series design with precision tooth geometry for smooth, consistent chain engagement
  • Bolt-on fitment using existing OEM sprocket carrier hardware
  • Manufactured to tight tolerances for minimal runout and extended chain life

Vortex sprockets are a trusted choice among sport bike riders and club racers seeking to fine-tune their gearing without adding unnecessary weight. The 438ZKV4-40 is a direct replacement that installs with standard tools and no modifications required.

Ordered the X20 replacement controller. It arrived quickly and is an OEM part. Matches my original controller that got ran over on the highway.

Found the right parts, ordered, showed up quickly. Works great.

Excellent price and excellent service. Unit arrived ahead of schedule. Much appreciated the excellent service.

Your online system would not allow me to put my Alaska address for billing, even though the order was to be shipped to Texas. I sent repeated emails requesting a phone call and no one would call me or provide me a number to call.

Good price and fairly fast shipping.

Excellent price and very easy to order products.

I would have liked to have more info on the item I bought on the web sight, I ended having to start a chat to get information

I have one of these on another boat. I love it and it's saved my lower unit more than once when I unexpectedly found a stump or hard bottom.. It also allows me to run with the motor higher because if the set back.
