Overview Vespa PX

The Vespa PX is considered the "VW Golf" among Vespa models and is one of the longest-produced vehicles from Piaggio. With its unmistakable design, robust technology and manual 4-speed gearbox, it has delighted numerous scooter fans since its launch and has become a cult object over the decades.

Vespa PX model history

The Vespa PX was launched in Milan in 1977, initially in 125 and 200 cubic centimetre versions. The 200 cc version was equipped with an electronic Ignition right from the start, while the 125 cc models were initially only available with a contact ignition. From 1978, Piaggio expanded the series to include the 150 cc version. This displacement class was also initially only available with a contact ignition.
In 1981, the switch was finally made to a maintenance-free, electronic Ignition for the smaller displacements as well as the introduction of an 80 cc version for the foreign market. In technical terms, the PX continued to be characterised by Drum Brakes at the front and rear, but was fitted with a newly developed front suspension with a combined Silencer/Spring element. The first PX models were also initially delivered without Indicators.
A major milestone within the PX series was the 1983 model leap to the so-called Arcobaleno, also known as the Lusso. This version combined various innovations such as the combined ignition and Steering Lock, internally locking Side Panels, a revised gearbox version, separate lubrication and a petrol level indicator. The Elestart was available as an option, and there was a body facelift with redesigned Frame Parts - from the Horn Cover and glove compartment to the Speedometer and the Cover on the Footboards, etc. From 1984, Piaggio also reinforced the axle pivot from 16 to 20 millimetres. The Vespa T5 appeared as a sporty offshoot in this context, although it is listed as a separate model.
To mark the 20th anniversary of the Vespa PX, Piaggio presented another revised version, the PX 98, which was equipped with a front Disc Brake as standard, among other things. The end of 2008 finally saw the provisional end of production in the form of the "Ultima Series", a special edition limited to 1000 units with chrome rims, chrome luggage rack, Whitewall Tyre and Wind Shield. the PX made another comeback in 2011. Due to the Euro3 emissions standard, however, only with the displacements: 125 and 150 cc. With the introduction of the Euro4 standard, production of the legendary PX finally came to an end in 2017.

The Vespa PX Engine

The PX series is powered by an air-cooled 2-stroke engine with a 4-speed manual transmission. Depending on the model and year of construction, the displacement ranges from 80 to 100 and 125 as well as 150 to 200 cc. A special feature is the gradual development of the Ignition: While the 200 cc was already equipped with electronic ignition from the factory in 1977, the switch to electronic ignition on the 125 and 150 cc models did not take place until 1981. With the introduction of the Arcobaleno/Lusso, further Engine improvements such as separate lubrication (separate Oil Tank) and a revised gearbox version were added, making the PX even more suitable for everyday use.

The used Vespa P80X/PX80 market situation

Anyone looking for a Vespa PX today will find a wide range on the used market in various price categories and conditions. Due to the high numbers produced and the long production time, the range is diverse, whereby original condition, good maintenance and a traceable history can increase the value. Rare versions such as the "Ultima series", special models or the sporty T5 are sometimes traded at higher prices and are particularly popular with collectors. In addition, the technology of the PX is considered robust and comparatively easy to maintain, which also makes it interesting for restoration projects. Where do you look for this vehicle?

The special features of the Vespa P80X/PX80

The Vespa P80X, a scooter model from the Italian manufacturer Piaggio, was produced between 1981 and 1986. It belongs to the "nuova linea" (new line) model series, which also includes the Vespa P 200 E. The P80X is often referred to as the PX80 in the vernacular. This model was later replaced on the market by the Vespa PX80E Lusso.
The PX80 model, which is not offered in Italy, fulfils a dual function. This "European" displacement class allows young people aged 16 and over to ride the vehicle in many countries in accordance with the legal requirements, with relatively favourable insurance costs. The frame and bodywork of the PX80 are the same as those of the Vespa P125X, with the Badge PX80 on the left-hand side.
In the following years, other models such as the PX80E Arcobaleno and Elestart were introduced. The names of the vehicles varied depending on the country in which they were marketed. In the countries where the Vespa is sold, it enjoys considerable success, especially in Germany. There it offers young people a vehicle that is the same size as the larger displacement models despite its smaller displacement.
There were two versions of the Vespa P80X. The first, which was available on the German market until mid-1982, was characterised by an externally mounted side cover cap. The Axle of the front head tube had a diameter of 16 mm. The second version, which was available from mid-1982 to 1986, had the side cover fastener under the Seat and the front head tube Axle had a diameter of 20 mm. This version is often referred to as a "hermaphrodite model". Indicators were integrated into the Legshield and Side Panels.
Some publications give the year 1980 as the date of release. According to our research, the P80X was developed specifically for the German market and appeared in Vespa shops in spring 1981.
The Vespa's Engine had a single Cylinder with a bore of 46 mm and a stroke of 48 mm. A Dellorto SI 20/20D Carburettor was used for the fuel supply. At a speed of 6,000 revolutions per minute, the Engine generated an output of 5 kW.
