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 equipped 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 for 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 PX 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 number of units 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?

Other Vespa PX

Earlier models of the PX were delivered without indicators, which today provides an additional nostalgia factor for enthusiasts. The Vespa PX epitomises Italian lifestyle like no other two-wheeler and combines timeless design with classic scooter tradition. Thanks to its long history of success, the numerous model variants and regular facelifts, it has permanently cemented its cult status and remains a living icon in the Vespa universe.

The special features of the Vespa PX 125 E

The Vespa PX 125 E is a further development of the original PX 125 and is characterised above all by its electronic Ignition, usually a 12-volt electrical system and often separate lubrication. It thus combines the classic charm of the early PX series - including the 2-stroke engine, manual gearbox and self-supporting steel body - with the advantages of lower-maintenance and more reliable technology. Minor changes to controls, instruments or the rear light provide a little more comfort without diluting the typical Vespa character.
