Rule may be too strong a word, but you would be hard fought to find another side-by-side that can cover all the bases as the Kawasaki KRX4 Blackout UTV does.
Are there machines with more power? Absolutely. More cargo capacity? Yes. But what you get in a factory offering is substantial. I could tell you the specs, and they would all sound fantastic on paper, along with the additional features that Kawasaki tacked on for the Blackout Edition. But instead, I decided to basically beat the hell out of it to see just how well it held up to varying conditions.
