Product Details

The Vortex 642AZRV4-45 is a high-performance aluminum rear sprocket from Vortex Racing's VTX series. Engineered for riders who demand precision, reduced weight, and long-lasting durability, this sprocket is CNC-machined from high-grade 7075 aluminum alloy for an optimal strength-to-weight ratio over stock steel alternatives.

Key Features:

  • Tooth Count: 45 teeth
  • Material: CNC-machined 7075 aluminum alloy
  • Series: VTX (Vortex) aluminum rear sprocket
  • Finish: Anodized for corrosion resistance and lasting appearance
  • Precision CNC machining ensures consistent tooth profile and chain engagement
  • Lightweight construction reduces unsprung rotational mass for improved acceleration and handling response
  • Hard-anodized surface treatment for extended wear life
  • Direct OEM-style fitment — no modifications required

The Vortex VTX aluminum rear sprocket is a popular upgrade for street and track riders looking to fine-tune their gearing while shedding weight. The 642AZRV4 platform is designed to fit a specific bolt pattern and center bore, making installation straightforward with standard sprocket hardware.

Came quick!

Great transaction, very satisfied.

The unit looks great and shipment was on point. Thanks!

Surprised how through the shopping experience was and my tire was delivered extremely fast will definitely be back for future purchases:)

Shipping was very reasonable and extremely fast!

I bought my item from them due to the original site I bought from kept telling me my item was back ordered and didnt know when they would have one. It was easy and painless to order and received my item in a timely matter. The price was good especially seeing what other sites were charging, not the lowest price but we'll worth the extra 20 bucks I paid. Will buy from them again if they have what I need.

Easy site to use and customer chat was excellent. BK did a great job answering my questions.

Thanks for having the original part.
