The Trautwein-Roller: MP3 in 1984?

“Are scooters steered with two front wheels conceivable? If you subscribe to the ideas of inventor Wolfgang Trautwein, vehicles of this kind may soon appear on the streetscape. […] Dr. Wolfgang Trautwein, 53, engineer from Meersburg at the Bodensee, received two original Vespa scooters in the middle of 1984 from Piaggio from Genova, in order to build prototypes. [This concept was] suggested by [Trautwein,] using the Vespa platform, exactly three decades after the first Motorcycle was equipped with a double-front chassis. Under their hoods, the Vespa tricycles hide the newest variant of the Trautwein front axle for motorcycles, a parallelogram axle […] Thus, the scooter effectively avoids wheel-flutter. […] The suspension is arranged so that the wheels do not only turn when rolling, but also tilt. The floorboards of the Vespa are firmly connected to the lower parallelogram, and follow its movements. […] Trautwein stresses that this changed style of driving comes relatively easily to the driver. And according to Trautwein’s statements, the chassis offers some safety advantages: Decreased hazard of front end slip on wet pavement, rails, etc. Safer braking, and improved cornering. Better handling. […] Space for a trunk over the front axle. […] Also, the comfort is quite convincing.”
