The Britten is the center piece at the Barber Museum. I could have studied that bike half the day and not cared about the rest of the floors of bikes. All the required parts are there, and you see them in their simplicity. The bike keeps your attention because it was designed by a true artist.
I used to think about how motorcycles would be had he not died so early. The reality is bikes would still be as they are now, running evolution of 75 year old concepts. Honda has managed to squash all creativity, even those within their own corporation and R&D.
John Britten's own mind would not let him continue with motorcycles had he not died. As soon as a creative brain such as his begins to feel the wall of bureaucracy it moves on. The limitations of superbike racing and the pressure of the manufacturers would press and he would have parked his project. For brilliance such as John's, had he lived to 90, life is too short to deal with corporate imposed rules to squash creativity.
He probably had 5yrs tops left of effort to put into his V1000 before he would have shelved it and was doing actual flight testing on his self powered wing suit.
