sorry i didn't think it was that silly of a question, seeing in the car world a 308 cubic inch motor built right can easily beat a modified 383 in the same weight car didnt think i was comparing a gsxr1300 to a ride on mower

You are correct, there is more than displacement that win determine a winner in any kind of race. The rider is the most important aspect of that equation. Ability, talent and preferences all come into the final test of which is best. If you are a 125 two-stroke maniac, love the bike and have trained yourself to use it to it's best potential, then you can drag race 450F's to the first turn of the motocross race and beat them, as I have seen before in the Expert class...
To get back to your initial question, which is faster a 250SX or a 300SX, there is no one answer that takes every variable into consideration. You might be able to race a stock 250 against a 300 and beat it, or depending on the rider you could have a highly modified 250 that would not beat a stock 300.
Really I'm not trying to be funny at all... there are just too many variables to answer that intelligently and with authority.
