2014 Yz 250 f
What class would the Yz 250 f be in when racing motocross? What bikes would be aloud to race in that class and last but not least could you put a big bore kit on your 250 and still race in the 250 class?
it would be in the 250 class and all 250f and 125 2 strokes are in that class. I think 250 2 strokes also would be in that class
