Nick, to answer your question on riding double, I saw the answer(in my opinion) on the internet lately. It was a bike that was a CF with a removable tail. When you removed the tail, there was an additional seat pad that bolted in place. It then looked like a scrambler.
Obviously, you couldn't stash electronics in the tail, but it was ingenious.
Personally, I like modular options. I always thought it would be cool to build an entire 'kit' for a bike so that you could change the entire look and color in 20 minutes by swapping bars, seats, tank, plastics, even wheels with different tires already mounted.
But I'm sort of weird like that :2thumbup:
