Introduction to the VS4

The Vespa G. S. Mod. VS4 has already proved to be a brilliant vehicle which, besides offering weather protection and driving comfort, is distinguished by outstanding performances (high average speed, brisk acceleration, ect.) that endear it to the most expert and hard to please users.

The Piaggio Co. has introduced on this high class scooter several noteworthy modifications with the purpose of improving its performance to the highest standards attainable. The braking system, though quite efficient, has been modified so as to eliminate the characteristic noise previously obtained due to special weather conditions when braking sufaces are worn. Now brake shoes pivot seperately on two pins with the consequence that the anchorage has been improved and any interference eliminated between primary and secondary shoes.

The STOP light device has been improved in that its components, consisting of an orange colored glass and a 10 W bulb fitted on the tail lamp, are more accessible and better protected. Its switch is operated through the rear brake pedal and is easily accessible for adjustment. The central stand has been secured in a better manner to the floorboard and provided with a modified stop, so that any possibility of excessive play and consequent vibrations after long operation is avoided.

The wheel rims are now more rigid and have a more pleasing appearance.

The engine cowling, still detachable, has been supplied with a new lock, more practical and easier to operate, which is partially concealed inside the frame.

Also, the transfer ducts have been ground, in order to increase engine power and elasticity with the same fuel consumption. The metal wadding in the air cleaner unit has been replaced by a special plastic material, which has proved very effective in the automobile industry.

The quality of the battery, rectifier, ect. (very important units as regard to the car-like, battery-coil ignition) has been considerably improved.

To sum up, we may say that, embodying, as it does, so many unconventional features, the Vespa G.S. is a very remarkable, fully proved machine, which more than justifies its leading position in the light weight two-stroke field.
