Will the 400ex keep up with me buddys yzf450 ? im considering a 400ex or 400z because of price and i can add mods to it but i dont want to get smoked bad on logging roads and flat ground. So should i get the raptor 450 and call it even or get the 400ex still have some possible respect out on the trail and sand ? I rode a 350 warrior one time and i could have used more power if that helps !
