Hey not trying to put down Rhino's here, but I've owned a rhino before, and I remember how much of a dog it was out of the box. The Yamaha has 10x better fit and finish then the Polaris products, but when it comes to performance and general dune capabilities you have to give it to the RZR. A friend of mine has a long travel Rhino 700 with sno-mobile clutch, dragon fire exhaust, intake, cdi, and full set of Skat-Traks and it won't come anywhere close to climbing the steep dunes that this RZR can. On the flats they both accellerate(spelling) and have about the exact top speed. I've duned with Jeff from JJ&A in his RZR that has LTE's, dobeck, and full set of STU's, and its just an animal when it comes to going down in to tree shots and climbing stuff that only quads could climb maybe 10 years ago. Just thinking I could use the money for something else. The unit will be hanging around the 300' track at Winchester this coming weekend at Dune-Fest.
