Ok so My friends went out and bought rzr 570 3 of them in the past 4 days. So I was thinking these could be run. So I started reading up on them and figured for the little bit of extra money I would buy the 800 with the wider suspension and the fox coil overs. Then I seen the 4 seater and i have three boys and figured this would be great father,son and brother bonding time. So I bought a demo one on friday it had 4 hrs on it and 44 miles. I noticed the back tires looked like the had been spinning them on the pavement I said something to the guy and also it made a whinning sound when off throttle he said that was normal. So I took it home. Later that night I went and rhode it with my friends well there 570's were leaving me I couldnt get past 40mph I figured maybe not enought room. So the next day I took it out on some land I went through a creek and it got stuck. It was not to deep then I put in 4x4 and it went back a foot them stopped. Water was now coming in the floor on one side. After I got pulled out it would not move like the belt was slipping I had to let it sit idling for about a hr before it would move. Even wide open field no faster then 42. I took it on the highway on down hill only got to 50. Then I was going up a hill not steep and felt like it was slipping again I got to the top got out had some one hit the throttle and the left tire spun not the right. Grabbed the axle and could tell the cv joint broke. I put 4hrs on this thing and 40 miles. Im almost to the point of taking it back and tell them I want a different one because I think this thing had problems already. I just thinkg 13k is alot to spend on something that breaks in 4hrs. Any thoughts about the top speed issue anyone?
