deogey, if you feel that is the machine for you, go with it! have many friends that are always saying they can ride this and that, but the go faster and better with the machine best suited with their wieght and style in this case you and the 400ex. it is a great machine and do not let anyone say that its too small or under powered for you. I rode a warrior for years and beat 400exs and banshees thought the wooded trails because i mastered the machine, it is more rider that machine.
