Product Details

The Vortex 840AZLV4-42 is a high-performance 42-tooth aluminum rear sprocket from Vortex Racing, a trusted name in aftermarket drivetrain components for motorcycles and powersports applications. Engineered for riders who demand precision, durability, and reduced unsprung weight over stock steel sprockets.

Key Features:

  • 42 Teeth – Direct replacement tooth count for compatible applications
  • Lightweight Aluminum Construction – CNC-machined from high-grade aluminum alloy for significant weight savings over OEM steel sprockets
  • Hard Anodized Finish – Provides excellent corrosion resistance and extended wear life
  • VTX Series Design – Features Vortex's precision-cut tooth profile for smooth, quiet chain engagement and reduced drivetrain wear
  • CNC Machined – Tight tolerances ensure proper fitment and consistent performance
  • Direct OEM Replacement – Bolt-on installation with no modifications required

Vortex sprockets are manufactured to exacting standards and are a popular upgrade for street, track, and off-road riders looking to reduce rotating mass and improve throttle response. The 840AZLV4-42 rear sprocket is sold individually and is compatible with standard chain sizes as designated by the 840 series specification.

The website was easy to navigate. I found the product easy peasy. Placed order and my order was delivered within days not weeks. I would order again from them if I ever need shocks again.

Tires in the add show studded tires but what I received was studdless tires . Will talk to THM Motorsport after this. But price was great

Good experience

I ordered my part on a weekend and received it by Tuesday. You guys are awesome!

That experience was great dealing with y’all very quick. I love you.
