Just like in anything you do...a lack of common sense, will get you in trouble. If you try to take a 90 degree turn wide open on asphalt or hard pack...yup, you're gonna flop !! I have had mine for almost 3yrs, and my buddy has had his since 05...neither one has been flopped...on a ride we took last sat, 3 different rzrs were on their sides though (and if you ask the rzr guys, they say the rhino is unstable !!) If you get one, make sure to put the wheel spacers on the back; and, remove the rear sway bar...you get more body roll; but, the bike will go better, lets the rear articulate better in the rough stuff.
