When is a motorcycle not a motorcycle? Alain Deveze's K-Pteron.

Via: Bikes in the Fast Lane

"Designed by the prize designer Alain Deveze (winner of the much coveted Lepine design trophy). He produced this QuadSide (for lack of a better word), He made the frame, inserted a Voxan engine and here's the stinger, the front and middle wheels all turn together

Both sides of the K-Pteron are platforms. You ride the K-Pteron like you would a sidecar, and with all three wheels used for steering, you can take the curves very sharply, so it's very maneuverable."
