A 2 stroke of the same CC as a 4 stroke will win every time assuming both machines are fairly the same in setup...etc. Sort of like comparing apples and oranges. (Honda Red and KTM Orange...Ha-Ha.) Both the KX and the CR are scary fast and unless you are very good hard to control the power because they make so much. If you are thinking about buying one, make sure it's not your first bike. I have been riding for a lot of years and I wouldn't consider having one in my garage...well maybe consider it but I certainly wouldn't race it.
