Interesting topic. I was thinking about starting something similar after hanging about on the Newbonneville site. That lot live for adding fake 1960's bling to their bikes and their constant fiddling and moaning about things that go wrong has the potential to raise my blood pressure, but that's another topic. Anyhow, they talk a lot about the style of exhausts or indicators or whatever else they are messing with.
I have no idea what style is, I simply don't get it (insert comments about dress sense here

). People tell me the Bonneville is a style icon and similar which I don't mind, if it gives them pleasure so be it. Ones who want to waste their lives telling me Triumph copied a '67 Bonneville but used a '73 clutch cover I try (sometimes unsucessfully) to come away from with a touch of diplomacy. I find the ones who tell me it isn't real to simply weird. GC, I imagine there are plenty of such loons who'll always have some sort of hiarachy with a Vincent at the top, BMW's in the middle and the XBR down a bit but do you really care? We all know the majority of people in the world will vote for a Honda C90 as best bike, but there are always a few that will try and ignore straight numbers and rate their BM GS or Ducati as better. It's individual choice, there is no right answer. I think the mass of popular thought in the bike world is coming to accept the world didn't end when BSA went bust, but I can't say if the XBR will ever be on the list of must have bikes.
I saw a BMW R1200S or something yesterday. I thought it looked good. Why? Thinking about it, it looked lighter than most BM's, possibly because the rider was about 7 foot tall and should have been in South Africa helping sort the Springboks out. The idea of a nice flat twin in a light chassis appealed. If I had the cash i might go look at one, but would decide I didn't want eight indicator switches and a CAN networked sandwich toaster where the fuel tank should be before any cash changed hands.
When I look at a bike I think about how it'll ride and how I'll keep it doing what I want it to. I can't bring myself to worry about some abstract notion that a new Tenere looks like a grasshopper or chrome is somehow good. I look at a Harley and think "nice motor pity about the fork angle/bars/pegs". I look at the Bonneville and think it's a great substitute for an airhead BM that I can't get in the condition I want for the money I have.
GC, are you saying a round headlight, teardrop tanked, European style framed bike would be somehow better than the same spec achieved by a different route? I think modern bikes get the spec wrong (don't need 150 mph if that means having my knees near my ears), but if there was a market I'm sure they could get it right. I'm betting you might still not like the result?
Sorry Niblue, I'd take the Deauville over a Harley too, which I guess places you style wise alongside a bloke who rides in a flasher mac
