So a buddy of mine got his wife an ACE last year. To date it has been on its side at least 3 times. To his wife’s credit, all by other people. I didn’t witness any of the tip overs, but I know one involved swerving to miss a rock or something and going up on the lip of a trail at low speed. I know it was low speed cause my wife was driving it at the time. She wouldn’t hardly go over 10 mph at the time. So anyways, the other two times may have involved higher speeds, but I don’ think they were excessive, just turning at speed. From what I was told, his 850 XP wouldn’t have had an issue making the turn. Granted, you can shift your weight on a quad, unlike in the ACE. I’ve driven it and it kind of has a feel to it that you need to be in tune with to run it at higher speeds and turn in corners and such in my opinion. Best to be in 2wd. I’ve driven it like a rally a car on some tighter trails with no issues. I’m not bashing the ACE, but I am curious if anyone else has had issues and what you have done to combat it since they are pretty liberal about letting others drive their ATVs, so just looking for some ideas on making it more stable. My suggestion to him has been to order after market rims to get the tires out a little wider and increase the base stance. He’s also looking at buying the tires I am pulling off my 570 touring. They are heavier than the stock carlises that are on it now by several pounds. Figure this may help a little too, but may also increase traction so it may be a wash. There are no top add-ons like a roof or anything like that to add top weight.

Appreciate any advise I can pass along to him.
