I have a 2006 Kaw. 650, they changed the name to "Brute Force". I bought it used three years ago with 300 hours on it. My first ATV, more powerful then I need but I thought I got a deal on it. It runs great. My only complaint is the Dunlop tires, they are two ply. I have replaced them with some six ply tires. Also, it is cold natured when first started. If I ever buy another, it will be fuel injected. I only hunt with it, I start it up about twice a month and run it around the yard to charge the battery. I have never had to use the 4WD to get it out of a bad place, I am not sure that 4WD is necessary in the hills, but it is nice to know that it is there if needed.
