I am looking at upgrading from my current bike (older 250 mx bike) and am not sure if I want to go with a newer 250 (00 yz250) or a cr/kx500. I like the idea of the new 4 strokes but the prices on used ones are still kind of high for me. I was thinking a 500 might be the best of both. I have a concern regarding the difficulity of kickstarting a 500 as I see guys have to REALLY kick them hard to move the lever. Anyways give me your thoughts, I ride mostly trails but play on the track with the kids once in a while - just for fun no racing. Thanks.
