I courently own A 450es. I have 27x12x12 superswamper vampires on it.My 1st ? is TO someone that owns A 500Rub, Do you think It has the power to turn 28x12x12 vamps in the nastiest mud? That is where I do most of my riding.Fuel milage is not real important,I can get 95-100km thats about 50-60miles before switching to reserve.Mabe some other comparisons,suggestions by you guys would help me on my decison to get the new 500,or not. 2000 450es Thanks.
