Overview Vespa PK

The 80s had begun and the Vespa PX was to have a little sister. In 1982, Vespa therefore expanded its product range with the Vespa PK, which was also to replace the V50 model series. However, many fans of the previous models found it difficult to get used to the new frame shape, as its angular design differed greatly from the previous smallframe models.
The PK models not only increased in size, but also received a number of technical innovations over the course of their model series. The new alignment of the bumper edges also meant that the weld seams of the frame halves and the Mudguard disappeared from view.

Vespa PK model history

The Vespa PK series

From 1982 to 1985, this model was available as a 50 cc, 80 cc, 100 cc and 125 cc. The era of the Variomatic also began with the PKs, in the form of numerous models such as Speedmatic, Plurimatic and Automatic.
Initially, the Forks of the V50 were still fitted, although these were still to be found as standard on later models. There was a so-called economy model, which was delivered without indicators, glove compartment, Speedometer, Control Light and Brake Light.
Even though the successor model was then equipped with the aforementioned components, the 50 cc versions in Italy, for example, continued to do without Speedometer and Brake Light.
The main feature of the first PK series is the small Speedometer without Fuel Gauge and the lockable side flaps that can be operated from the outside. The Vespa 125 ETS was added as a sporty special model in 1984. We will list its special features separately.
Another special model was introduced in 1985 with the PK Lusso. Numerous components made their debut here, which then became standard on the XL. There were also separate models or different designations for various countries, for example the "SS".
In 1986, the PK was finally replaced by its successor, the PK XL.

The Vespa PK XL series

Colloquially known as the "XL1", it was first introduced in 1986 and featured numerous changes, including a revised frame.
The larger Glovebox allowed the Horn to be positioned behind it and the Horn Cover was given a slimmer design. The Speedometer was equipped with a Fuel Gauge and integrated Control Lights as standard. Locking of the Side Panel Door was moved under the Seat, giving the scooter a much cleaner look. The Seat was also given a new design.
The typical Floor Runners, as previously known, were replaced by Floor Mats or "Floorboards". The XL versions were also quickly followed by various special models: starting with the XLS, which scored points with its higher performance, through to the sporty PK "Rush" model.
A new regulation in the Italian traffic regulations at the time allowed the previous power limit of 1.5 hp to be exceeded as long as the speed did not exceed 40 km/h. This meant that the 1.5 hp limit could no longer be exceeded. As the 1.5 hp limit was no longer applicable, the rated power of the PK "Rush" was increased to 2.3 hp. However, in order to comply with the permitted top speed, the decision was made in favour of a 3-speed gearbox.
The leap to the upcoming XL2 is clearly visible in the Vespa PK50 N (Nuovo). A special version of the "N" is the legendary "Roberta", which was decorated with flying butterflies. This was a collaboration between PIAGGIO and a manufacturer of women's underwear. However, there is contradictory information about this: Official dealer letters attest to this version, while pictures often show models based on normal XL versions that do not correspond to the Nuovo line.
Visually, this model already features typical applications such as the attached rear with recessed Rear Light, as well as the mono Seat that merges into the rear, Hub Caps and the new plastic mudguard. The Handlebar itself is still the typical XL1 handlebar with round Speedometer. Although the glove compartment remains unchanged, it has been given a Tray, as is familiar from the Vespa T5.
The last models of the PK XL rolled off the production line between 1989 and 1990, depending on the engine capacity. After that, the era of the XL2 began.

The Vespa PK XL 2 series

Even though the series partially merged due to numerous special models, the actual market launch of the so-called XL2 was in 1990. A typical feature is the completely redesigned Handlebar with its completely redesigned large Speedometer. While all previous models had a moulded Handlebar Lower Part, the XL2 introduced tubular handlebars with a two-part Cover for the first time. The gearstick actuation was also new: instead of the usual two shift cables, a single rigid shift wire was now used, which enabled a more direct gear change and lower-maintenance mechanics.
Locking of the glove compartment was combined with the Handlebar / Ignition Lock, which required a new type of lock carrier. The operation of the cold start aid moved from the frame step-through to the Handlebar, making it much easier to reach.
The Clutch was also revised as part of these changes. The familiar clutch with a central spring was replaced by a version with six smaller Springs. A ball-bearing Pressure Plate and a toothed pressure plate with Release Lever rounded off the system in its new form.
Of course, there were also various special models for the XL2; some changes had already been seen in previous special versions. Probably the best-known special model is the HP4 (High Power 4 marche), which achieved higher performance with a revised Engine.
There was also another version with a 3-speed gearbox, which was marketed as the PK50 HP.

We have probably overlooked some things here or failed to mention certain special models. As there is a lot of overlapping information on the PK models or even manufacturer information is sometimes contradictory, it is often difficult to clearly assign them to a specific model. When even official advertising brochures give different information than the PIAGGIO Garage Hand Books, it becomes complicated to establish clear facts. We therefore ask for your indulgence if our information differs from your experience. We will be happy to correct or supplement our databases with your help.
The XL2 was probably built until 1996 - as far as can be researched based on current knowledge.

Used Vespa PK market situation

Anyone looking for a Vespa PK today will find a wide range on the second-hand market in various price categories and conditions. Due to the high number of units and the long production time, the selection is diverse. Original condition, good maintenance and a traceable history can increase the value. Rare versions, such as the numerous special models or early variants without Indicators, are sometimes traded at higher prices and are particularly popular with collectors.
In addition, the technology of the PK models is considered robust and comparatively easy to maintain, which also makes them interesting for restoration projects. Unfortunately, not all spare parts are available anymore, which means that it is sometimes necessary to resort to reproductions or used parts. Where do you look for this vehicle?

The special features of the Vespa 125 PK ETS

The Vespa PK 125 ETS represented the sportier version within the PK series, with innovations that had previously only been introduced in the later XL version. These included features such as an extensive glove compartment and a Fuel Gauge. The frame number of the Vespa is located on the right-hand side below the Side Panel Door on the engine side, specifically on the top left-hand edge. In terms of visual features, the Badge "P125 ETS /elestart" is emblazoned on the left-hand Side Panel Door, giving the vehicle an unmistakable character. Comfort is provided by the double seat bench, under which both the Tank and a small compartment for tools are located, which emphasises the practicality. Riveted Floor Runners, of which there are two on each side, ensure stability, which not only serves functionality but also emphasises the design.
Production of this model series was limited to just two years and was aimed exclusively at the Italian and English markets. As the most powerful smallframe Vespa, it is considered the counterpart to the T5. The ETS was available both in a version with Kickstart Lever and in a combination version with Kickstart Lever and Elestart .
The Engine has a specially labelled Cylinder Head ("P 125 ETS"), a model-specific ETS Crankshaft with higher intake timing and a Cylinder with three transfer ports and a Piston with a large window. There is also a double-spring Clutch, a specific Flywheel (991155 PKM) and a glove box similar to that of the PK XL, but without the Badge and the corresponding holes. The Carburettor, a Delorto SHBC 20 L with a three-hole Intake Manifold, dispenses with the Sleeve, which rounds off the technical features of this Model. The Exhaust, known as the "ETS Banana", is also unique to this model.
The Vespa is characterised by a number of model-specific features that give it a unique appearance and improved functionality. The Seat is specially designed for this Model and features a white "ETS" print; it is also equipped with its own plastic holder for the seat latch and a Luggage Hook. The look is rounded off with black and silver Stripes on the side flaps and the Mudguard, which has a special groove and space for the Stripes.
The Front Cover (Horn Cover) is reminiscent of the XL2 Model, but has a distinctive edge instead of being rounded. Other characteristic details include a narrower leg shield surround compared to the PK XL, a Handlebar similar to that of the PK XL Lusso with a flat Cover and a PX-style speedometer with Fuel Gauge. The Mud Flap extends the frame shape, while the Indicators correspond to those of the Italian PK Automatica and are positioned lower at the rear. The tank is similar to that of the PK XL, but has no recess for the cable opener, a screw-on metal fuel filler cap and a fixed connection for the Fuel Gauge.
