Product Details

The Vortex 642A-56 is a precision-engineered aluminum rear sprocket designed for high-performance motorcycle applications. This 56-tooth sprocket features 520 pitch spacing and is part of Vortex Racing's premium 642A series.

Key Features:

  • Constructed from 7075-T6 aerospace-grade aluminum for exceptional strength-to-weight ratio
  • 100% CNC machined with proprietary saber tooth groove design for increased sprocket longevity
  • Unique tooth profile reduces chain wear and improves power transfer
  • Lightweight design reduces unsprung weight for improved handling and acceleration
  • Silver anodized finish provides corrosion resistance and clean appearance
  • Made in USA with precision manufacturing tolerances

Vortex sprockets utilize a patented design that extends service life compared to conventional sprockets. The 642A series is engineered for 520 chain conversion applications, offering riders the ability to reduce weight while maintaining strength and durability for street and track use.

I ordered a tire from thmotorsports that the manufacturer had discontinued two years earlier and which I could not find anywhere else, without checking customer reviews first, something I never do. Had I checked reviews first I would never have placed the order as the reviews I read after placing my order were uniformly awful. But rather than call and cancel the order, which was my first impulse, I resisted the urge to do so and waited. A day later, the shipping update said my tire had shipped, so I waited. Another day later, the shipping update said my tire would arrive a day later by the end of the day so I waited. On the appointed day, the tire, exactly the tire I had ordered and which was unavailable anywhere else, arrived at the end of the day, brand new, in perfect condition and I was utterly amazed. Thank you, thmotorsports, I am so glad I did not look at your reviews before placing my order.
