The 400ex is a good bike. Can't go wrong with it or the Warrior. The warrior is way less expensive to mod, but, the Honda is getting to be the same. The EX will handle better, and has a better seated posistion (ergos). But, when it comes down to it, you can get a well taken care of Warrior for less then a beat up EX. The warrior can offer two ways to start it, the Honda only has electric. Any EX built before 05 will not have reverse, the Warrior can go in reverse while in any forward gear. Both are great bikes, the EX has it beat in some areas, but, with a little smart use of money, the Warrior can beat the EX in those areas.
