I owned a wonderful early eighties
Gianni Motta Personal a while ago and loved the bicycle, even though it was a tad too big for me to ride comfortably. You have a very nice bicycle, there, and should offer great ride quality....
You can figure out the vintage by applying the information contained in
How Old Is My Bicycle?, if you are interested in doing so. You might even have a bit of fun doing so. You might also want to have a look at the
How To section of my website, for a bit of guidance about doing this or that to the bike.
Good luck and lucky you.
