I own a 2013 Ranger 500 two seater and a 2015 570 four seater. I have put my little one through pure heck (even crashed it a couple times) since I bought it in 2013. It's never let me down. I use the 570 for hunting now but I am really impressed with every thing about it. Smoothest ride compared to any other sidexside I've been in. As someone posted above the cab noise (due to engine location) is also quieter than any other sidexside I've been in as well. Power, I have a dog box, front rack and with 6 dogs and 6 people in I have had no issues with needing more power. With all the extras on it, it will still flat out leave my smaller 500 in a race. From what I've read the 570 is only 2 horsepower less that the yamaha 700's.
the ones ive been in were loud as well. Im deaf in my left ear and loud noises make it hard for me to understand folks..you have to holler at me. Haha..i get on folks nerves sometimes with it. But its only when there's loudness going on. If i get in a room full of folks its real bad. Lmao.
