I owned a 2003 GS for a while and while it is a great bike, they are very top heave and tall. At 6-4 that was not an issue for me.
My neighbor had an R1150R that had the ABS, like my GS. It was a replacement for a Ducati Monster he had laid down. He ended up selling it to a friend of mine and even plugged into a battery tender I remember it eating batteries.
For old times sake, here are a few pictures. I really enjoyed riding the R, and like has been mentioned they are very forgiving.
My GS and pair of pups I had back then. I loved the Jesse bags as well.
The funny thing about this one that is my daughter, who is 20 and a junior in college.
Lastly, I hated the 1200GS, rode a few when they came out as I was thinking of upgrading, never liked them.
