I think Pilbara's treatise on design is spot on.
Some day the motorcycle design and even the seating position will be changed, it's a throw back to riding horses after all.
Maybe when some suspension patents run out things will change?
On another note: if I had a pair of wheels like those I'd take them to bed with me!
