i dont think u should get either, u should get a trail bike if ur gonna ride trail like an ttr 250.. 4 strokes at least the 450's over heat when u ride alot of trails at slow speeds, even just when they idol to long. And with a 125 two stroke unless if you stayed fast and on the pipe u could be in risk of constantly flooding it. thats just what i think though. good luck
