Product Details

The Vortex 642CZBV4-45 is a lightweight 45-tooth aluminum rear sprocket from Vortex's VTX series, engineered for performance-focused motorcycle riders seeking improved acceleration and reduced unsprung weight over stock steel sprockets.

Vortex sprockets are precision CNC-machined from high-grade 7075-T6 aluminum alloy, delivering an exceptional strength-to-weight ratio while significantly reducing rotational mass compared to OEM steel sprockets. Each sprocket features hard-anodized teeth for extended wear resistance and corrosion protection.

Key Features:

  • 45-Tooth rear sprocket for optimized acceleration and throttle response
  • CNC-machined from 7075-T6 aluminum alloy for superior strength and light weight
  • Hard-anodized finish for enhanced wear resistance and corrosion protection
  • Precision laser-cut tooth profile for smooth, quiet chain engagement
  • Direct OEM-style bolt-on fitment — no modifications required
  • Significantly lighter than factory steel sprockets to reduce unsprung rotational mass
  • Part of Vortex's VTX sprocket lineup, trusted by racers and street riders alike

Vortex is a leading American manufacturer of high-performance motorcycle sprockets and racing components. The 642CZBV4-45 is a direct-fit replacement designed for easy installation, making it an ideal upgrade for riders looking to fine-tune their gearing for track days, canyon carving, or everyday street performance.

Delivery man was excellent. The AC unit was plug and play.

Everything came in really quick and packed well. Apparently I just ordered the wrong part.

Awesome experience! Would definitely do business with you guys again

Ordering was easy

Excellent price and very easy to order products.

Quick and fast and reliable

Only complaint is with UPS-paid for 2 day shipping, but evidently that does not include weekend. Ordered Wed night, THM processed on Thurs morning promptly. Didn't receive item till Monday. Other than that, A+ for THM.
