Vespa 160 GS (2nd series)

From model year 1963, the GS 160 undergoes a facelift. The seat is now dark blue. The small compartment above the rear light has disappeared and a large luggage compartment is now located in the leg shield. The engine remains unchanged, only the air filter box and the carburetor jetting have been changed. All GS 160s are delivered in lead white gray (MaxMeyer code 1.298.8714).

The engine is still piston-controlled. The cylinder has a 58 mm bore and a solidly built full cheek shaft with 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 construction period. 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, as the 100 km/h are quite optimistic.

The frame and all sheet metal parts are identical to those of the GS 160 Series 1. The front suspension is similar to that of the 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. The rubber mat familiar from the smaller models is in the step-through.
