The X's biggest weakness IMO is the lack of a rear locker or really stout limited slip diff. The times that I have seen people get in trouble on the trail it has been because of traction. They had to use momentum or too much skinny pedal to do what they were attempting. That being said. The X is a very capable vehicle, stock. And with very minor mods (tires, sliders. etc.) its abilities can be enhanced greatly without too much $$ or effort.
