All large bikes suck in sand. It's doable, but not fun by any means. Unless you have a true dirtbike or light weight actual dual sport like a DRZ, KLX, etc., you'll hate it. Dirt and gravel are a breeze, and even a little mud with the right tires.
The battle of GS vs. Strom has been going on basically since the strom came out. If you type just that in your google search, you'll find pages upon pages of arguments for and against both. The Uly has even been tossed about in those conversations and for good reason (it's a very capable bike...opinion wise...it's not the best or smoothest feeling, but capable) and for whatever reason now the Versey.
Every bike offers something different to the rider, some better at things obviously then others...you've gotta decide what best fits you and your needs, etc. For me it's the weestrom. There are always people around willing to let you test ride bikes....join enough forums and you'll be able to ride what ever it is you want before you know it. Trust me (I'm a bike testing whore).
I looked at the GS before purchasing the wee. 1st...every used gs I looked at seemed to have an issue and the issues seemed re-occurring. Even read in multiple threads on bmw forums about the issues. That in itself seemed pretty sad. That expensive of a bike, you would think BMW would fix the glitches right away. Apparently not. Also came to find that a lot of bmw owners have a lot of tech days. Personally, I'd rather ride.
And lastly...It's the principle of it all... bmw owners are like a high school cliche' of preppy rich kids. I didn't want nor was I a part of it then and I won't be now.
There I said it.:rolleyes:
