The Valkyrie DID have a fairing version, called the 'interstate'
It's fairing was more batwing-ish and the details, down to the taillights, had a muscle-cruiser flair to it. The Goldwing, while a fantastic bike, is not really much of a cruiser. Even the the F6B to me, is still a sport tourer. In MY opinion, the F6B is going to butt up against the BMW's and Honda's own ST1300 as the 'ultimate' in sleek sport touring. The riding position and styling is a lot more sport than cruiser.
Fantastic bikes though. Being $4,000 cheaper makes it tempting, it puts it in the price range of the touring-cruisers (Voyager, Electra Glide, etc.), which is a big plus in Hondas favor. I suspect people will be putting aftermarket top boxes or even fitting Goldwing top boxes on to these things and just making them a poor mans Goldwing. (Although a $20,000 motorcycle doesn't exactly sing poverty, LOL). I really think Honda could make this a home run if they include a quick-disconnect kit for a matching top box. The top box on the Goldwing is more 'integrated', and the bike itself doesn't quite 'work' without it. (For starters, it contains the taillight and some essential components, such as I believe the actual stereo unit, Honda just uses a 'control pad' up front, as opposed to an actual head unit in the fairing like H-D and Kawasaki) This bike however, could be a really cool 'convertible' tourer with a quick disconnect top box, similar to how Harley does with the street glide or electra glide.
All in all I like the F6B, but I don't think it's revolutionary. I certainly don't think it's a replacement for the Valkyrie Interstate.
I like the CB1100 also. I am secretly hoping Kawasaki follows suit and re-introduces the KZ series of motorcycles. Now that both Honda and Triumph are making clones of their past models. I know triumph uses 'fake' carbs complete with non-working choke knobs, and even non-functional sync screws and all sorts of little components to make it look exactly like the older carb setups in order to house and disguise the fuel injection system. I wonder if Honda is doing similar?
