Saving every last vintage motorcycle is like designating every old building as "historical". Eventually you're going to run out of room and steel. The reality is that every bike will eventually be melted down and re-cycled; maybe in 5 years, maybe in 500. The whole point of the motorcycle is to have fun with it. Ape hangers or clip-ons; if it brings more people to motorcycling we all win from motorcycle friendly laws, more aftermarket support, etc. Sure, they charge way more than I would pay, but I don't care what they spend their money on.
For instance: What's wrong with cutting up an 80's dual sport to create something fun?
