My F800ST was the most sensible, and most boring bike I've ever owned. Finally decided that since I only go through life once, I wanted to feel like I was riding a motorcycle when that's what I was in fact doing. If I ever swing back from passion towards sensibility, the GT might top my list.
Judging from the photos, looks like they may have increased the seat-to-footpeg distance. I felt this was the biggest weak point of the ST as a tourer . . . a true torture device for the knees.
