Infos Vespa 'U'

The Vespa “U” was built as saving model. The selling price in Italy amounted to at that time lire xxx. - thus only lire 20'000. - less than a normal Vespa. The idea with the U-model was probably therefore not established :)

Characteristics of a Swiss Vespa 'U'

The model was imported 1954 into Switzerland. The numbers of the imported vehicles varieren depending upon source between 4 and 8 pieces. The Vespa U was type-examined on 4 June 1954. The importer made a set of changes particularly for Switzerland:

Tacho Vespa (VDO), scale to 70 km/h, gold, only with a screw at the front metal installs. Winkeltrieb to the rear wheel.

Theft safety device Because no steering wheel lock was present, the importer attached a lock with the carburetor flap. So the thief could not open the Gasoline cock.
Number supporter in front Is missing unfortunately only the holes are still there.
Combination brake brake the rear wheel is also braked (turning both feet off at the mountain makes possible during braking).

But the original brake pedal had to be removed, because the second rope could not have been installed otherwise.

Steering stop The Swiss vehicle control required a steering stop. Because that is missing with the Vespa U a larger saddle was been used (of the model 1951), so that the steering wheel lines up there.
