will the 250r waste a 250x that is beefed up a little? it really isnt beefed up alot but it will beet a 300ex.

 

250r 250x the 250r will smoke it no question in my mind U are comparing a 250 2 stroke to a 250 4 stroke thtar is like apples and oranges. it takes a 400 4 stroke to make the same amount of HP as a 250 2 stroke that is why the AMA allows 400ex's in the 250 class
