Cast are lighter, forged are heavier. Which is better? I have a bored out yz 250 and have a wiseco in there now but have always been a fan of Pro-x pistons. Im going to continue with the wiseco for awhile longer but was considering getting a pro x one next and was just curious what you guys have ran into for expirence with both.
