Vespa scooters are a great way to get around town or travel long distances. Some models, like the GTS 300, can reach speeds of up to 80mph. Vespa scooters do not come with a windshield, though. One can be purchased separately in a kit from a Vespa dealer. Installing a windshield will help to block the wind and rain while you travel. Installing an aftermarket windshield is easy and should take no more than one hour.
Clear the Vespa headset of all attachments. This includes the mirrors and any aftermarket parts you added, such as mirrors or racks. To remove the mirrors, turn them counterclockwise until they release from the headset.
Position the holes in the windshield brackets over the holes on the headset just below the handlebars. Thread the bolts included with the windshield brackets through the holes with your fingers until they hold the brackets in place. Do not tighten them yet.
Slide the windshield support arm into the brackets. Tighten the bolts on the windshield bracket with a socket wrench.
Position the plastic windshield so that the bolt holes fit over the holes on the windshield support arms. Put the remaining rubber washers over the remaining bolts and tighten the windshield to the support arms with a crescent wrench.
Reattach the mirrors and any aftermarket parts to the Vespa.
Take the Vespa for a test drive after installing the windshield. Adjust and tighten the windshield as necessary.
Do not over-tighten the bolts or you could damage the windshield brackets and crack the windshield.
