I know of a few of these - 11 digit pre production prototypes, some had production style frames, some with castings. They were all 11 digit frame number bikes and went on the road to the press. It appears legit (although it has been modified of course) there is another 11 Digit one coming up for sale soon too
I love the authentic serial number I've just checked my bike and it seems I have the first Panigale ever made too! At the time they couldn't even decide on the name? That'll make it worth a good couple of grand more when I sell it. Look: :Cigar:
I have checked with the seller and he has told me the frame doesn't have the number on it !!!!! so it is just the bit of paper
