I owned a 74 CB750 and as much as I like this new 1100, I have a couple of concerns regarding its longevity in the US market:
1. At an MSRP of $10k, it's well above the median for the "retro" market. By way of comparison, you could buy the top-of-the-line Triumph T100 for almost $1000 less than the MRSP of the Honda. Additionally, both Moto Guzzi and HD also offer "retro" bikes in the $7k-$8k price range. So that handicaps the 1100 from the get-go.
2. More significantly, I doubt Honda's commitment to this platform. This isn't the first time a Japanese manufacturer has tried to introduce a "big naked" bike in the US. Remember the naked Bandit 1200? Remember the Kawasaki ZR-7? The Zephyr? The CB1000? All those bikes had two things in common: They were big naked standards, and they were dismal failures on the sales floor.
IMO the reason that "big naked standard" bikes don't sell in the US is because the market segment that prefers clean, unadorned bikes has been completely taken over by HD and its imitators, IOW, the cruiser market owns them.
And the people who don't like big cruisers typically want things like fairings, luggage and other stuff that big naked bikes lack.
So in order to sell a "big naked" bike in the US, you have to appeal to a customer that
(a) wants a large bike with no fairing and a big round headlight, but also
(b) doesn't like v-engine "cruiser" bikes.
That's a very small segment of the market and not enough to sustain the importation of a large number of bikes to the US, which is why the efforts to bring big naked bikes to the US have consistently failed for the past 25+ years.
