I wasn't there, but a friend in SoCal was and I asked him to grab some photos of the AT. He said there was considerable interest in the Africa Twin, lots of people lined up to sit on and view it up close.
His 9 year old grandson took the first one of Bill on the silver AT; he's about 6'2", 250 pounds. His sense of the AT is that it's sized between the VStrom and MultiStrada (he's owned both) and it feels light. Second photo is of another attendee (size and what he is doing are unknown). It gives a good sense of the lower body egronomics - and it looks comfortable. Three engine cutaway shots, another of the AT and one of the VFR1200X Crosstourer, also on display.
