I'm sorry I didn't reply to the question about comparing it to the Monster.
It's a totally different bike, very much sports tourer as far as the riding position is concerned. I used to have a Honda CBF1000F and that was very upright, more so than a Monster and I loved that bike and its riding position, good thing about it was the seat height could be changed in a few minutes. Not all of us have long legs, I've got an inside leg of 29" and with ongoing back problems and being late 60's I'm very much constrained by seat height. I quite like KTM's but wouldn't (couldn't) own one. If you can get to try a new VFR800 it's less of a sporty riding position than that.
My last bike was the BMW R1200RS which I found super comfortable even though it wasn't as upright as the Honda. The Supersport is a very deceptive bike. It looks like a sports bike, it would be easy to just walk away, but I'd heard it was going to be a more relaxed riding position so was really chuffed when I sat on it. I've now sat on several and it's just the bike I've been looking for, it ticks all (but one) the boxes for me. It's such a **** handsome machine. The only box is I haven't ridden one yet. But hey, does Ducati make a bad bike?
So I would say if you want to get some idea of the riding position go visit a BM dealer and sit on the RS.
I'm finding it almost painful waiting for it, I've looked at pictures, scoured the web and the Ducati website looking at the accessories already released, so roll on end of March early April. Build slot is in March.
