My Brother has a Z400, and I can honestly say...The Warrior is no match in a flat out drag race. He has me on the top end, and pulls me thru all the gears.
NOW, when we get in the woods, I can usually best him. The Warriors low end torque really pays off, when **** gets sticky. I hopped on his bike in the dunes, and killed it twice, as 1st gear is real high, compared to the "Beast". I also noticed my front suspension handled the whoopties and bumps better than his(surprising enough).
I won't lie, I still want something faster, so I'm thinking of adding a KFX(I hate the Z's, they were just as common as the YFZ 450's) a DVX, Predator, or the new Honda 700r, to the mix. I will always keep my Warrior, but damit I want to go FASTER
