I've got some excellent footage of our 3 120's running up Georgia Pass, south of Breck in the Tiger Run area, having to go around a 4 Seat RZR that the left rear aarms were ripped clean off the machine. I have no idea how they were going to get that off the pass, it was a pretty rough trail. We stopped to help but they said they were fine and had help on the way. We rolled on by, on the way down huge rain storm hit, I know they got soaked... LOL. My dad's Ranger 700 was brand new when we hit Wheeler Trail and it would over heat... when crawling. He sold it when we got back, only had 10 hrs on it. My RZR blew the front wheel bearings out twice in different trips back to back. Seemed like there was always something. The local Polaris dealer was worthless, I wouldn't trust them working on my weed eater.
I will say we had great luck with the Teryx's though, that is another good rig. The 4 seaters have alot of CVT whine though. My 2 seater wasn't as bad. My 2 neighbors run Teryx's and love them. I sold mine and went with the NH 120's, I've had 2 now, 1 4 seat and 1 2 seat that I converted to 4 seat, but its easily converted back to 2 for yard work.
