Basic ergonomics. The operator's portion of the seat is dished, which lets you touch the ground. And note the position of the pegs, especially the distance to the seat. Remember, that's already a pretty aggressive riding position, though not quite as radical as a GSXR or a 675.
Now, take a look at the passenger section. It's up higher and the seat is rounded off. The pegs are a lot closer to the seat. It's even more radical than the operator's position. There's nothing to give the passenger any sense of security - she's perched up there in what is basically a squatting position and leaned forward to hang on and stay out of the wind.
Now, this isn't too bad for short runs, but it's not something you'd want to endure for any amount of time.
I have a friend with an older Honda Hurricane 1000. Ergonomics are similar. His wife won't ride with him any more because she's just not comfortable.
Now, as a rider, I find the TT seat very comfortable. Way better than the stock seat on my Speed Triple. But it's just not passenger-friendly.
