Contact a Vespa dealer. You are the end user and the bike came from a dealer. The dealer is Vespa's actual customer. The dealer has the numbers to contact Vespa. Make them earn the profit they charge when the bike was purchased. Below is Vespa's customer service number. I need to warn you, using the terms "customer service" and "Vespa" together are generally considered oxymoron's. Please rate my answer. Thanks.
