I've got a GS and Concours-14 in the garage, just added a mag-wheeled Bonneville and I'm in love with it.
I was eyeing the CB1100 REALLY hard but for my intended purposes, I could not justify the extra $3.5K for the Honda....probably the first rational decision I have made when it came to motorcycling.
After swapping out the shitty stock shocks and seat, I would have no reseverations taking the little guy for a multi-day ride far from home.
It's more home in the backwoods and streets vs. open highway, but it has no real issues cruising 80MPH. I think it would be up to the riders own personal comfort level keeping it there for long periods of time, more than the bike itself.
