First series (1997-2004)

2001 Piaggio Liberty first series

Presented at the Barcelona motor show in May 1997, the Liberty was born as a scooter with a 50 cm³ engine intended primarily for young audiences, having highly innovative specifications, it immediately stands out as "high wheels" among the most popular on the market; thanks to its original and dynamic line, good design quality and competitive price.^[1]

In September of the same year, the version with a 125 four-stroke engine was presented at the Milan show and went on sale a few months later.^[2]

In 1999 the Liberty LE 150 was introduced with the 150 cm³ four-stroke engine equipped with catalyst approved Euro 1 followed in December of the same year also by the 50 LE and 125 LE models approved Euro 1.^[3]

Second series (2004-2009)

Second series Liberty

The basic model with a displacement of 50 cm³ was proposed both in version with two-stroke engine and with four-stroke engine. The higher displacements are instead exclusively four strokes.^[5]

From the middle of the year 2006 the sports version, the Liberty S, came on the market, characterized by a fairing similar to the Beverly 125 and an unprecedented instrumentation. It was slightly updated further in 2007 by re-proposing the 150 engine instead of the 200 cm³. A peculiar trait, in its category, is the attention to detail and the evident search to present captivating and well-finished finishes together with original saddle fabrics.

The Liberty Delivery 125 cm³ version was also chosen by Poste Italiane as a scooter for the distribution of correspondence.

The Liberty has a single cylinder engine air-cooled for all versions, "LEADER" for 125 and 150 cm³ and "HI-PER" for 50 cm³.

The presence of high wheels limits the capacity of the compartment under the saddle that it can contain various objects and just a jet helmet; on the other hand, the large tank guarantees good autonomy.
