To answer the original question...
The process of buying a brand new BMW as far as I can tell is:
1) Go on a generously long test ride
2) Come back literally unable to imagine life without buying the bike
3) Order the bike - WHICH WILL NOT HAVE BEEN BUILT YET
4) Wait up to 8 weeks for the bike to be built, shipped and prepped
5) Get bike
If you want one quicker, you have to buy a used one.
This is partly about the level of demand relative to their manufacturing capacity and partly to do with the spec-list. Your bike will be built for you because it will have what you want on it.
If you bought an R1 you'd get an R1 - there is no option to add ABS, traction control, electronically controllable suspension settings, heated grips or extra power outlets. But with a BMW you have to choose if you do or don't want each of these things, and most of them can't be added on later because they would require so many of the standard parts to be swapped out to fit them.
Its exactly the same if you buy a BMW or Mercedes car (or any other manufacturer with a proper spec-list). It seems really strange at first, but you get used to it. Then you go in a Toyota showroom, and are shocked to find there is no worthwhile spec list and you have to have it the way they want you to have it, and you go back to BMW/Mini.
I can see this isn't the answer the original poster wants. Why am I posting? I don't want someone else to stumble on this thread later and come away with the impression that the ONLY reason he was 'treated' that way by the dealer was because the dealer was being unreasonable.
Actually if you think about it this way, it makes you wonder if the BMW dealers are better set up to weather this financial storm. Unlike the mainstream dealers, they don't have a warehouse full of crated bikes their manufacturers forced them to buy as part of the franchise. They have to finance their showroom and staff, but they don't have to service the capital tied up in mountains of unsold new stock. Meanwhile, back in Germany they also are not running themselves financially into the ground producing yet more bikes that have no demand and pumping them into the supply chain. Because almost every bike on the production schedule already has a buyer's name attached to it, if the showrooms get less orders they just build less bikes. Its still not profitable but its not as cataclysmic as what goes on with the likes of Ford and General Motors in the US.
