First of all, you do not need to seek permission to write a story of this nature. As we all know by now, when it comes to motorcycleing, technology is shared across the board weather it be atv's, dirt bikes, or street bikes. I am an atv rider as well as a street rider however, even if I did not ride atv's it is allways nice to know what is going on in the industry.
Now about the quads. The Grizzly 660 seems impressive and looks impressive (my local dealer has a camo one in stock)according to other mags, there is a serious competetor that even the big grizz can't tumble. That quad is the Kawasaki 650 V-Twin Prairie. The Prairie has the best motor, and a smaller physical size compared to the grizzly. The Grizzly is nice indeed but if you have seen it in person you will know why they call it the Grizzly...because it is as big as one. I can't imagine that riding one of these as not being a chore or tiresome. I personally have a Polaris Xplorer 250 and while half the size of these new power quads, it does everything that I ask it to for nearly half the price.
