Depending on the tread, such a scooter tire swirls a lot of water and dirt on the scooter, which may not necessarily dirty your own scooter, but the more so the person behind it. Especially in the corso, which is so popular with Vespa riders, everyone is happy if the person in front has mounted such a mud flap. The scooter rider, who is of course not altruistic, thinks for himself and not only installs such a mud flap himself, but also gives it to his scooter colleague.
