I used to do some nutty stuff with my KLR that I wouldn't even consider on my GSA. Of course I wouldn't want to slab it a couple states over on a KLR to get to some trails. Even on the KLR at times I was wishing for a 250 in the rough stuff. Like it was said above smaller is always better. Love my GSA but on Long way Around I bet they were wishing for something smaller most of the time, but that's another thread.
