I owned a 2015 570 before I bought my 700. My 570 had gas boiling issues when the tank was under half full which resulted in the driver smelling gas until the tank was filled. Their stock spark plugs on the 570 are junk. I had a rear suspension squeak on my 570 that I only got rid of by antiseazing the bushings in the aarms. I did like their 4wd and that's the one thing I do miss. I'm not bashing 570s, just listing some things I encountered along the way. The wheelbearings went out on the 570 around 1200 miles which may be normal, it spent alot of time in water. The Yamaha dealer gave me more for my trade in so I went with the 700. I am very happy with my 700 so far but have only owned it for four months. No issues with it so far.
