    The ones I had were too poor to put in my 125 !!! I sold them at a discount rather than use them.

    I've never used them. The lower price does seem attractive, but Wiseco has NEVER let me down. I gladly pay the little extra knowing I'll get a consistent product.

    I use Pro X in my KDX 200. They seem to be okay for that bike. I had a Wiseco crack in the same engine. Have always used Vertex in the Huskys.

    The same company owns wiseco and prox. Not sure how that all works though. It's for a different brand bike so its OEM or prox. Decided to go on instead of saving 50 bucks

    We sell Wiseco, JE, and ProX. All three brands are owned by the same company, PMI. Typically, this is how they compare to each other:

    ProX - Cast piston, similar to OEM, economically priced.

    Wiseco - Forged Piston, improvement over OEM, medium price.

    JE - Forged Piston, premium product with all the tricks, highest price.

    Depending on what you are building and how you use it, a ProX piston is an excellent replacement for the OEM piston.

    but pro-x makes forged pistons as well?...still much cheaper than the opposition.


    Correct. Some ProX pistons are forged, but most cast.


    this is from Millenium Technologies

    Plus my last 2 Wisecos came in lovely soft bags. Nice touch.

    I was told that Pro X pistons are a way to market pistons that didn't pass quality control for Wiseco or whoever. Friends who have used them, all have had early failures. I use OEM, Vertex, or Wossner.

    Pro X are cast rather than forged.
