Friend of the site, Paul in North Carolina, emailed me awhile back when he found a Sears smallframe 125. He ended up buying in, and got it going with a little tinkering. As you can see in the photo above, the Sears 125 has some unique features. It was a one-year only model for Sears, and was sold the last year that they sold Vespas. It has the "mickey mouse" tail light that was produced by Siem to comply with US regulations for that year only. All in all, it was a great find, and you can follow Paul's adventures riding it on his blog.
Sorry!
"Tu vuo' fa l'Americano" is correct.
