Disclaimer: I was there only two weeks. I didn't ride, the chorale I was photographing had a rigid tour bus schedule, and only part of the time were we in Northern Italy. And my experience is five years old. On the plus side I have two complete galleries of photos for you to see (my wife shot the other one, and I taught her all I know
).
Actually, I didn't even want a scooter until after this trip. My wife bought a European Smart Car when we got back, which 1000 became available about 10 months after our trip, through a limited importation through Canada. It's still our main car.
As you go north the scoots get more $$ and modern, more Asian too. If you go as far south as Naples (Napoli) the streets were littered with garbage, but there were folks riding older Vespas around...one guy missing a cowl on a primered PX or Rally did a block long wheelie for our tourbus.
To the point: Fav cities were Venice, Venice, and Venice. But no Scoots. You need to walk into the interior and get lost on the side streets. Yes they have streets, next to the canals. Lose the tourists. What people don't know is that when you get lost, since it's so small, you eventually come out somewhere. It has it's own light to the sky. I hope it is not covered in water in 20 years. It would be a great loss.
After this I recommend Siena. Our tour people tried carefully to get us to here especially, they were proud of this sleepy little town. Siena and Florence were apparently rivals end of the middle ages...then the Black Death came along and wiped out Siena more than Florence, so the story goes that I was told.
Florence is very crowded, but you have to see the art there. Our local Italian tour people told us not to drink out of the fountains (only) in Florence...I don't know why.
I did a lot of walking in traffic in Rome, and it's hectic. There's a lot of eye-contact driving rules, or something else that dictates who goes first.
Lastly, time of day. Everything does shut down in the middle of day. Everyone eats late and spends a long time at dinner. You might be eating from 20:00 to 22:00. Enjoy it, the food is one of the things Italy is most known for.
