5. Rune prototype


Produced for just one model year, 2004, the Rune was not a huge sales success, but it does serve as a highwater mark for just how inflated the pre-Recession custom craze had gotten before reality prevailed and the bottom fell out. Honda’s designers journeyed where no man had gone before, and the production bike isn’t that far from this prototype. It’s lined up in the museum next to cars that still look futuristic. If you already have everything, very nice very-low-mileage Runes are out there for $15K. If I were a cruiser guy, I would have one.
