In 1956, a decade after the first model was launched, the
millionth Vespa came off the line at the Pontedera factory.
Following the initial products from 1946, improvements were
made to the original design and new models were introduced. The 1948 Vespa 125
had rear suspension and a bigger engine. The headlamp was moved up to the
handlebars in 1953, and had more engine power and a restyled rear fairing. A
cheaper spartan version was also available. One of the best-loved models was the
Vespa 150 GS introduced in 1955 with a 150 cc engine, a long saddle, and the
faired handlebar-headlamp unit. Then came the 50 cc of 1963, and in 1968 Vespa
125 Primavera became one of the most durable of all.
The
Gran Sport or GS 150 was unveiled in 1955, a blend between style and sport.
It was the first sporting scooter to achieve mass market success.
the
styling was the pinnacle of Piaggio's scooter design - it had a smooth and
integrated design. The body was physically bigger, the cowls' curves were
exaggerated and made even more round than those on the Vespa 150. In fact,
from the sloped tail to the curved legshields there was hardly a straight line
anywhere on the scooter. Even the floorboards were concave.
the
150GS was the first to be fitted with a 4 speed gearbox, the carburettor
increased to 23 mm and a larger exhaust was added to help the engine
breath.
The 150 GS is remembered as being the world’s most
beautiful scooter ever produced and is highly sought after by today’s
collectors of vintage Vespas.
The scooter public had grown up, had changed. The Vespa
had become the means of how to stand out in a society which was slowly
coming to terms with a new social entity: youth.
For the first time, a vehicle born as a quiet way for
lots of people to get about suddenly discovered it was capable of breath
taking performance.
Born from the Piaggio racing team experience, the GS was
the first scooter with a 150 cc engine and was highly sporty in concept. It
had a direct fuel injection engine generating 8 bhp at 7,500 revs and
reached a top speed of 63 mph. It had a four-speed gearbox, and its long
saddle and large 10" wheels gave the Vespa line a new, aggressive look.
