I'm trying to figure out if a XR400 or a CRF450 would be best for me. I 'm an intermediate rider and ride mostly in the desert at higher sustained speeds (not really into the track). I want something comfortable, low maintenance, and something that I can "cruise" on when I get tired. I KNOW the XR400 will do this, can the CRF450 do this as well, or does it "want" to go fast at all times?
