The LX 150, like all modern Vespa scooters features a 4-stroke single overhead camshaft and steel frame construction.

[1] The LX models feature an automatic torque slave transmission and front disc and rear drum brakes.

The LX, like all other Vespa scooters, has a steel supporting body that also contains a 9.8-liter tank inside; it is combined with the typical single-arm suspension on the front wheel.

The 125 engine belongs to the Piaggio Leader family and is a four-stroke with electronic injection and has a power of 7.9 Kw (10.7 HP).

The Vespa S was introduced on the market in 2007, after the official presentation held at the Milan Motor Show the previous year.

It derives from the LX model, from which it stands out for numerous aesthetic details, such as the rectangular headlight, the minimalist mudguard with the chromed crest, the front bow tie, the squared rear-view mirrors, the red suspension spring and the back shield with the pouch instead of the classic glove box.

Some of these details, such as the rectangular headlight and the squared mirrors, recall the aesthetics of the old "Vespa 50 Special" produced in the early seventies.

In 2012, the new 125ie and 150ie 3-valve engines made their debut,[9] while the aesthetics were mainly renewed with the black finish for the horn cover and the fender crest, instead of the previous chrome.

Finally, the standard equipment has been extended to include black 5-spoke alloy wheels and the central footboard with the Vespa logo has been introduced.
