I have a 2011 700 cat it runs great and more power than i would ever need my only complaint is the power stearing it pops up a code if you start the quad to quickly and it freaks out every once and a while but my dealership claims they know what is wrong with it. but other than that i love it runs great i only have 80 mile on it 10 hours but 90 percent of that was pushing snow. hope this helps u hit me back if you have any questions about it
