An Old Moto Guzzi.

It is a Moto Guzzi 1965. Model: 74cc Dingo.
I remember that one of my grandparents had a bike like the one as in the photo, and in that bike (the bike of my grandfather)I rode many times when I was a child. I also remember that he said "Hold on strong to me. " I loved to hold on to my grandfather, and while he was driving cautiously, I think I never travel safely on the bike.
