Product Details

The Vortex 642CZLV4-45 is a 45-tooth aluminum rear sprocket from Vortex Racing's VTX line, engineered for riders who demand lightweight performance without sacrificing precision. Manufactured 100% in the USA, this sprocket is CNC-machined to exact tolerances, ensuring true concentricity and consistent chain engagement.

Key Features:

  • Lightweight aluminum construction — significantly reduces rotating mass compared to steel, improving throttle response and rear-wheel power delivery
  • 100% CNC machined from a specially formulated alloy per Vortex specifications for optimal strength-to-weight ratio
  • Lightening holes further reduce unsprung and rotating weight
  • Anodized finish provides corrosion resistance and the iconic two-tone machined look Vortex sprockets are known for
  • Unique Vortex tooth profile promotes longer sprocket life and smooth chain engagement
  • 45-tooth rear configuration allows for gear ratio tuning — adding rear teeth increases low-end torque and acceleration

About Vortex Racing: Based in the USA, Vortex Racing has been manufacturing top-quality racing components since 1995, with products trusted by professional road racers, motocross competitors, and performance street riders worldwide. Their sprockets are developed and tested with direct input from top-tier race teams.

Replace your worn OEM rear sprocket or fine-tune your gear ratio with the proven quality of a Vortex aluminum rear sprocket.

I've had nothing but oof experiences doing business with THMotorsports. Best price for spark plugs out of anyone else. Fastest shipping with reasonable rates.

Well-designed website and search, prices and checkout experience was nice.

19 August - So far, so good - Awaiting delivery...

Incredibly easy to find the part and price is great.

Happy, just didn't get confirmation email after order was placed.

I was hesitant to order from this site at first but was order was processed very quickly. I did pay the extra 9.99 for 2-day shipping and it took about 5 days for shipping total

Good deal thanks
