I'd tend to agree with the comfortable part for big guys but I havent even touched either of my DS650s in a year or so. My wife's outlander 650 max xt is fun to ride and comfortable as heck and now I have a polaris RZR so that's pretty much all I ride (drive).

I miss the DS650 in the dunes but am really havin fun with my RZR and trading off on her Outlander.

In fact I'm going to try and sell one of the DSs just cause there's no more room in the garage or toy hauler!
