I just bought my first Vespa (2006 GTS 250) for my wife and I'm trying to figure out why the turn signals don't make an audible click. My Yamaha Vino 125's and my new Kymco Yager 200i all make a nice loud and tacky clicking sound making them impossible to leave on. Not so the Vespa. It's obviously not a cost consideration. I see from your excellent web-site all kinds of home made modifications to make noise but why don't the folks at Piaggio build it in standard? Do dealers offer a dealer installed modification?
