Just did a 2000 km trip to Emilia and Tuscany, and back.
Stayed away from known cities and known motorbiking famous roads; my friend and I wanted to do the hills and the low passes, where there's no mess.
For anyone interested you can do a Google street view around these places:
Montemignaio, Piobbico, Poppi, Caprese Michelangelo, Mombaroccio.
Just ask me, should you need more infos.
