Just joined the forum today! I have a new 2015 XP 1000 EPS and took it out this past weekend for the first time. I had a 2013 800S which I traded for the new rig. I absolutely love RZR’s and hope to use the new one quite a bit this summer. I live in Colorado so most of my riding is on trails in the mountains – we do have a few sand dunes which will let me experience the full potential of the new 1000! I had to take it back to the dealer as soon as we got home – strange noise in the drivetrain. Dealer says it is coming from the front diff and that the noise will go away after 50-75 hours. The noise only happens when I am in High (no noise in Low) so I’m not sure I buy the dealer’s explanation. I have read several posts about front-end noise on the 1000 but haven’t found any that talk about the noise only happening in High. Anyone else having this same experience?
