Love my ZR800...first season with it, 400 miles plus and still love it. I traded a ZRT800 and thought I might be disappointed, but not at all. Gets up to 100 very quickly. Haven't topped it out yet because none of the lakes were frozen a couple weeks ago, but was up to 110 or so on a couple straight trails with plenty of throttle left...was afraid of little Bambi running out in front of me!! The trails is where this sled really shines. Rode some of the roughest trails in my life a couple weeks ago, and never felt like I was beat to hell after I got off. Like many of the articles say, this sled just gets better the rougher the trails get. None of my buddies ride Doos, and the ones that ride tripple Yami's didn't go with us a couple weeks ago, so who knows what would win on a straightline, but they won't beat me on the trails.
