INTRODUCTION
The "PIAGGIO Co" welcoming you in the family of the Vespa owners, wishes
to thank you for your preference, trusting that this scooter will be of your full
satisfaction.
For its own characteristics (comfort, low fuel consumption, noiseless running,
neatness etc.) the Vespa can have a large field of use; for work reasons as well
as tourist trips, both along large highways and narrow farm roads.
Long and hard rides will not worry you and, driving the Vespa, you will soon
realize its excellent performances.
This booklet, in which are described the simple instructions for the use and
maintenance, will enable you to know better your own Vespa and use it in
the most suitable way.
