My son drives my RMAX4 1000 everywhere and does very well with it. (Got the rmax as it was the only 4 seater that I liked that would fit in my camper) I was thinking the 570 for him but noticed that in 2017 they widened and lengthened the 900 XC. I think 900 may be too big. Is the 570 really that tippy (Seen a lot of Youtube Videos) Or is there some kind of a Performance mod like in My rmax and the CanAm that reduces power for a child to ride? Also, am I overly concerned by 2 factors the power of the power of a 900 with a young man who is a very capable driver, vs the tip-over risk of the 570 over a 900 with the extra stability? I am sure this has been asked but I could not find something that addresses this scenario.
