One question- security. What's it like generally? If you avoid the urban areas. I'll take my Squire chain/Squire padlock.
I've been told Italy can be dodgy.
I always camp on Italy trips, feels safe with bike next to tent, never used a lock or chain, northern Italy is the wealthy industrial area. I wouldn't park my bike in Manc or Milan & walk away from it. Do as here. Ridden to Italy 20+ times, since '99 to Milan British bike owners rally, often twice a year. Moniga (south end of lake Garda) is 2 days easy, stopping in Vosges, then paying the Swiss vignette & straight through. Also spent a week getting down to the Adriatic, a more enjoyable way, with 2 night stops in Vosges to ride the Ballon then toll free route thro' Swiss Alps riding the passes, your choice. The T800 in my experience will do 60mpg bimbling along B type roads but down low 40's at 80+mph M'way. Fuel light on 30 miles before my usual fuel stop in Lux, the 1050 does that easy. Fuel is cheap in Lux. Dear in Belgium.
A Scottoiler or similar saves faffing about with the chain on a long run, carry a cable inner kit with enough tools to fit it, & tyre repair kit with a good mini compressor.
