I agree. Most of us really want that 1000cc beast, but will be fine on a fraction of that. I have ridden my sons 250 Ozark and its carried me no problem. It's a bit small framed for me , but it carries my weight and moves along fine. I'm 6'3" and 210# . I have never felt like I didn't have enough power on it. I fell cramped on it because of my height, but that's it.
I love my Vinson 500, but really want a 750 King Quad. Part of my "Need" for the King Quad is that 750 motor that I don't "need", I just want. The other part is the IRS. I like the cushy ride. The Vinson is a SRA. Otherwise it's an AWSOME machine that I truly enjoy.
