The bike lived up to expectations, there was a lot of motorcycle traffic and there wasn't a bike I saw that I would rather be on. We averaged 80 mph on the open roads (the K1200S wouldn't go much slower) and a reasonably sane pace in the twisties.
The Airhawk extended seat time by a factor of 2 or 3, I could run a tank through the bike without stopping, which left me a little stiff but ready to get back on once the tank was full. I would definitely recommend the Airhawk.
The 20" Cee Bailey provided good protection (6' 2", 30" inseam) but there was a lot of buffeting at 80 mph, fine at 60 mph. In contrast, the K1200S was jet-smooth at any speed, but it sets your butt on fire in no time. I need another 2" more windscreen or less height to put the top of the screen on the nose of my helmet and make the Cee Bailey work all day - a work in progress.
I bought a BMW rainsuit which obviously kept me dry and really helped in the cold.

Peyto Lake, Bow Summit, Icefields Parkway, Banff National Park, Alberta
The trip covered the southern interior of British Columbia and southern Alberta. No pictures of the southern interior of BC - twisty roads, no time for pictures and southern Alberta which is God's Country on a sunny Sunday morning.

Windmill Farm east of Lundbreck, Alberta

High upper winds near Cowley, Alberta - hence the windmills
New favorite road in British Columbia = Highway 31A between New Denver and Kaslo, fresh pavement, no traffic and a real treat. We had a local on lovely 84 Honda Ascot pacing us which is probably the only reason I didn't wind up in the rhubarb. The road was built on the old rail line and there were several decreasing radius turns that required prudent entry speeds!
Great trip, GREAT BIKE!
