Vespa Cosa

The Vespa Cosa is a motor scooter from the Italian manufacturer Piaggio, which was built from 1988 to 1998.

Model history

Piaggio wanted the technically obsolete Vespa PX replace with a new model and at the same time bring in new concepts. You leitere the new development of the PX from because you wanted to keep the classic design principle with self-supporting steel body and full rocker gear, but there was a plan to use a water-cooled four-stroke engine and an automatic transmission, which was later discarded. Nevertheless, but were of the emerging automatic scooters some ideas in the Vespa Cosa that you wanted to call first Vespa R ( rinnovata, modernized ), taken as a storage compartment under the seat, a hydraulically actuated integral brake system or an optional anti-lock brakes on the front wheel (EBC ). In addition, the Cosa, the panel used in the subsequent models Vespa ET and Vespa GTS parts of the steel body with plastic became widely known.

The Vespa Cosa is thus directly successor for Vespa PX and is the last newly developed Vespa with manual transmission. The Vespa PX but was built in parallel on and is still in production even after the end of production of the Vespa Cosa.

Technical Features

Always been one of the integral brake hydraulic standard equipment in the Cosa. By the pedal both wheels are braked by hydraulic drum brakes. The hand brake is applied, as in older Vespa models, via a cable on the front wheel. It is intended only as an emergency brake or parking brake for hill-starts and is not intended as a service brake.

For an extra charge the Cosa was also available with an electronically controlled anti -lock braking system on the front wheel, this system was called at Piaggio EBC (electronic brake control ).

The engine of the Cosa is essentially an evolution of the engine, the Vespa PX series. While the internal engine components of both series are almost identical, the motor housing differ in three points:

  • The swingarm pivot Cosa is wider than that of the PX
  • The receptacle for the rear suspension of the motor housing is shaped and placed otherwise, as the rear suspension Cosa is longer than the PX
  • The installation space for the rear brake anchor plate is designed differently to accommodate the hydraulic brake

The carburetor of Cosa was always provided from the factory with an electric fuel tap and an automatic choke. These details were an absolute novelty for Vespa scooters. Also new was the electronic tachometer that has been integrated in the central analogy completely differently designed instrument panel. Previously, only the Vespa T5 was equipped with a tachometer ( digital initially, later models Analog).

Generations and variants

The series is divided into two generations. The first generation was built from 1988 to 1991, from 1992 he was the second generation is called ( for facelift ) as 2 or as Cosa Cosa FL.

Both generations are technically but fundamentally the same, the engine variants were identical in both generations. Modified the clutch, which could be operated with less force and the transmission was fitted with a new cable and easier to turn. Likewise, the instruments got a new drawing. Differences, there were also at the bottom, which was now above the license plate and just below the seat, the license plate support and the seat. The seat of the Cosa 1 has a side lock and was rather the PX modeled. The seat of the Cosa FL was, however, made ​​wider and more comfortable and had other handles. The castle is located in the back of a region which was also painted in the vehicle color.

All versions are equipped with a fan-cooled two-stroke engine with three transfer ports including inlet control via a rotary valve and a draw key circuit with four courses, which is operated by a twist grip on the left handlebar.

1) In Germany, the Cosa 200 was also offered with a 10 hp, which she was to cheaper insurance. Varying the control times of the cylinder and the ignition timing.

Known Issues

Among friends Vespa Cosa was ( wrongly) discredited, which is based on four problem areas:

  • Despite hydraulically operated drum brakes need to be adjusted manually, and this depending on driving style quite frequently, otherwise the pedal travel without pumps is not sufficient to establish the full braking power
  • The cylinder of the hydraulic brake leak during long periods or due to old brake fluid.
  • The body leans to the area of ​​the main stand to cracking in the sheet and in a row (since the cracks through the rubber mats are not immediately visible ) corrosion damage
  • When starting via Kickstarter, it often unintentionally to the touch of the foot and front apron which the latter can result in damage to
  • The electric fuel valve can fail; However, it is possible to bridge it with a bypass valve.
  • Cosa all generations jump on bad cold, which is due to the construction of the petcock. A post- dreisekündiges - right tilt (on the motor side) facilitates cold starting much.
  • Due to the small height difference between tank and carburetor, it can at high loading and semi- full tank cause fuel shortage of the carburetor.

There is no E10 released by the manufacturer.
