Yes there are a couple of DS 90's. And there are some AC quads. There the same quads. My son rides a AC 50 in the 50 class rider #838. We haven't had any problems with water . And the other AC 50 rider hasn't had any problem with water either. The one Pred 90 that got wet was in the air box which give some trouble but he still won his class. There was a Bombardier 90 also he never had any trouble with his yet. My son has hit creeks way over his tires, never a problem yet. If this quad can take what he can put it trough then it will go thru anything. Mud ,water jumping you name it.
