Hi,

I am from Malaysia. Just got my ER-6F about a month ago.

Is there one place in Rome where I can go shop for the following products:

1. Helmets - MOMO, Caberg, Nolan
2. Motorcycle Apparels - Hot weather Apparels (Jackets, Pants, Boots etc etc)
3. Givi Monorack fitment kit 445FZ

Please advice. (Reply in english will be greatly appreciated)
