I have a King Quad 700 and i love it. I am only 15, so of course I had to test out the speed. I got it up to 71 mph and it easy pops wheelies. But, it is also great for hunting. I have ridden in 3 inches of snow, up big hills, and down steep ridges many times without using the four wheel drive. This thing is really amzing because it can go through literally anything without using the four wheel drive or differental lock.
