I have been researching the 2016 900S and the 2016 1000S. The only difference i can find between the two is you get 25hp more with the 1000S and of course the the price is higher. I have seen were people are saying the 2015 900s has plenty of power for the trails and riding in the woods. So what Im wondering is that the 1000S is worth the more money just for power that I probably wont need?
