Looks like a stock Ruckus, but he apparently made changes to the variator to increase acceleration, which in turn decreases top speed. And a 50cc Ruckus is barely faster than a bicycle to begin with. I love the look, but I wish they would build at least a 125 or 250cc version WITH THE SAME LOOK. The short lived "Big Ruckus" looked like a lawn mower to me.
