Gone but not forgotten-The Phueled Type 1.

Via: Jalopnik

"Whither the mad inventors? Right hither. Part motorcycle, part four-wheeler, the Type 1 prototype was influenced by Star Wars speeder bikes, Japanese manga and Elf enclosed-motorcycle prototypes of the 1990s. Its builder, an automotive engineer, set out seven years ago to create a new automotive construct for urban areas. Drawing on a combination of digital and real-world modeling, he fabricated the result primarily using common shop tools. Powered by a 1990 Yamaha FZR 600 cc liquid-cooled, DOHC engine, fed by Mikuni carburetors (stage 3 jets), producing around 91 hp, linked to a six-speed tranny, the rear-drive Type 1's wheels are set at 60-degree angles and offers (for what it's worth) integrated side-impact protection."
