alright i gues what i said wasnt entirely true [img]i/expressions/face-icon-small-wink.gif[/img], but speaking the truth the stock 400ex motor isnt so great, it will have plenty of power for the average trail rider but dont expect to beat the newer 400s and high perf. quads. If your into balancing tricks i heard the ex is great. so i guess thats where the fun comes in.
