Local specialty hardware bolts

Those stamped metal nuts are actually tension nuts.  A jam nut will hold but put constant force on the bolt whereas the tension nut will not and allows the bolt to turn if shocked.  I wouldn't use a jam nut there.

Thanks for the tip. I guess I'll have to go to the Duc dealer after all.

They are called a self locking counter nut. 

You can find them pretty much anywhere that sells an extensive metric selection.

probably buy a bag of them for what the dealer will charge for 1.

They are also a sponsor of DESMO fyi.  http://www.desmoducati.org/

Their shipping is a little high for small orders, but if you're ordering in some quantity it works out.

I used them to make some bolt/screw kits for my dellorto carbs on my older bikes.  I think it's 7 or 8 total small bolts and they look much nicer with the socket cap button screws instead of slotted screws. 

Exactly why I ordered an assortment of M6, M8, and M10 bolts in multiples and various lengths for present and future use.
