We run a grizzly 660, two bruin 250 i think and a yamaha dirt bike. I use the grizzly and during the winter it doesnt see much use, but in the summer its not unusual for me to put 60 miles a day on it. I would recommend that what ever brand you buy get the automatic transmission. I can stop back up and be after a cow faster than anyone else can with the other bikes. They all have manual transmissions and my bike is the only 4 wheel drive. Our choices here are limited to honda, yamaha, and kawaski. The honda dealer here is hard to deal with and the service tech is really slow and sometimes his repairs are not the greatest. The other dealer carries both the yamaha and kawaskis, their service is ok but has its problems as well. We like the yamaha because they are reliable and easy to handle. We noticed that the kawaskis were a lot harder to turn and took more space to turn. We use the bikes for just about anything, from checking, working cows, to building fence. It is lots of fun to be riding across a pasture checking cows and realizing that the antelope in the pasture are racing along beside you just to see how fast you can go.
