I looked at atv's this past summer and it came down to the Prairie 650 and the 660 Griz. I went with the Griz for a couple of reasons. I asked both dealers at what point should I not go any deeper in water. The Kawasaki dealer said no higher than the floorboards. The Griz dealer said dont go over the front racks as this is where the air breather is. Big difference. Also I liked the looks of the 660 and the powdercoated racks they come with. As far as power I thought the Prairie had a small edge.
Honda used to be the only bike I would look at. But this new trans they have scares me. You dont repair it you spend $1600.00 plus to replace it. On the belt drives about $40.00 plus labor and your good to go.
You cant go wrong with either one I think
