This recumbent motorcycle looks like it has been strongly influenced by the Japanese movie Akira. These renderings are very cool but since I do not read Japanese I can't tell you anything about it. From the looks of it, it appears to be powered by an electric motor, which could be the cylindrical object behind the front wheel, there are also no obvious exhaust pipes anywhere.
If any of our Japanese readers or anyone else who can read Japanese cares to elaborate on the writings from the site, please do.
If someone designs and builds a functional electric motorcycle like this, I'm in.
Thanks to Bob Horn for the tip!
