I am looking to do my first pro race up in canada this summer and am looking for some advice. I prefer 2-strokes over 4-strokes because that is what I grew up on, and can't really afford 4-strokes upkeep but they each have their pro's and con's. I will be riding the lites class so this is 250f vs. 125 4-stroke advantages -the eastern pro canadian tracks are mainly sand and 4-strokes are better in sand -power advantage of 4-strokes 2-stroke advantages -lighter -cheaper Because of the new pro age rules in the U.S. I have to wait till I am 18, so we decided to try our luck up in canada. I have always trained hard so the fitness aspect is no issue. I am young, but have always been up front at all the amateur nationals so we figured why not try it and see how it works out. Let me know what you think, the money aspect of the 4-stroke upkeep is the main reason that we are leaning against it because money is tight right now as it is for everyone but the power advantage that it has makes it a hard decision.
