Vespa 160 GS/4 (VSB1T, 1962, GS4)

Vespa 160 GS (1st series)

In 1962, a large-frame successor to the Vespa GS 150 was presented. The Gran Sport 160 (VSB1T) is a completely newly developed vehicle, which is a completely independent development that has nothing to do with the GS 150 VS1T. Only minor details such as the handlebars and rear light have survived from the last series of the GS 150 to the new model.

The engine is still piston-controlled. The cylinder has a 58 mm bore and a solidly built full cheek shaft with a 60 mm stroke. A Dell'Orto SI 27/23 carburetor is used, the jetting of which is changed several times over the course of the build. The engine runs very smoothly and pulls away cleanly from low revs. Once again, the conditions in Italy must have been extremely favorable when determining the top speed, so the 100 km/h are quite optimistic.

The frame and all sheet metal parts are completely new. The front suspension is similar to that of the later PX series, with suspension and damping in one element. For the first time, the standard spare wheel is housed under the left-hand side cover and concealed with a semi-circular metal cover. Aluminum trim strips on the side covers and front mudguards lighten up the lines of the bulky sheet metal parts. In the step-through is the rubber mat familiar from the smaller models.

The first series of the GS 160 is the only Vespa to have a glove compartment above the rear light. A small flap provides access to a compartment in which a pair of gloves and other small items can be stowed. The seat is gray.
