I am thinking about buying a 03XR400, my first bike ever was an XR250 which i loved and was great to learn on, since then I have owned various 125 and 250 MX bikes and have liked them all in there own way, I ride trails, and occationally in desert and am a fairly agresive ridder. I would like to know what the power on the XR400 is compairable to, like is it faster than a WR250 yet does it get smoked by a WR450? I obviously have never ridden one and do not want to regreat it, I know it wont be as fast as my CR250 but that is half the reason that I want one, smooth bulletproof trail power.
