Vespa scooters are simple to ride, but there are a few things you need to know in order to shift gears. First, make sure your clutch is fully engaged. Then, take your left hand off the handlebars and place it on the gearshift. With your right hand, shift the gear into neutral. Now, use your left hand to push down on the clutch pedal and pull the gearshift into first gear. You're now ready to ride.
