This past weekend, I was riding with a Raptor and a 400ex on my Warrior. It was an alright day....that ended in me breaking my footpegs and snapping my chain....Now, we were riding on this one trail that led to a road...you turn down the road and it leads to another trail if you turn off to the right...well it was block off by trees...again...so we turned around and went back up the road and onto the trail again....it was kinda hard on this trail...it was all rocky with a spot with two decent ruts that go upward only for about 5ft....The raptor I was riding with was widen 4 ft from stock (Durablue +4 axle with flipped front tires to make it equal) so he had no problem, My quad, I went right up the ruts...then the 400ex....he had some problems...he tried to go up...he sat and spun...we pushed back and had my friend drving the raptor try to take it up on a ledge...he flipped it right over....so we eventually had to push it....so, what are 400exs really made for?...they seem like they have a lot of trouble on my trails...
