I have an '04 AC 650 LE with 27" Outlaw tires on it. WHEN running, this four-wheeler can't be beat. People tried, and failed. This thing just goes anywhere, through anything. However, I will not buy another AC again. I've had to use my warranty one too many times and have to do so yet again. This four-wheeler is not reliable at all. Give me a Kawasaki Brute Force or a Suzuki.
