This is a relatively pointless exercise in pedantry, but were there any hard and fast rules about what was stuck on the side panels or was it just a typical Friday afternoon job of whatever came to hand?
From the dates stamped on mine, one is from 2003 and one is from 2001. Both have black and silver chequered flag stickers, but no Italian flag and no text.
Looking at ebay side panels, most I can see have either text denoting the model variant, or an Italian flag plus the chequered flag. I found one similar to mine on a Cafe sport, which my bike is not.
Of course, the panels may have been replaced, but they are the right kind of age and condition to suggest they are original.
