I am a very happy Polaris 600 HO owner. While in the UP I got to have a short ride on a Rev. I am short so it fit like a glove. My fusion is somewhat rider foward and greatly improved over the past but does not compare to the rev. I would like to get a rev, but every website and foroum I go to I hind people talking about expensive motor problems. I put a lot of miles on and try to get two years out of a sled before I trade. I have concerns about committing to a rev after having many years of very dependable polaris motors.
