Once registred you enter a sort of online supermarket where you can choose the items you want to buy. They have in catalogue many OEM parts for 906 and 907. 750 is not present at all.
I just sent them an email with my shopping list. I hope everything will be OK because it often happens that US sellers are not willing to sell and ship abroad (maybe one day someone will tell me why).
This online shop has a VERY USEFUL feature: with a simple trick it is possible to read the Ducati PART NUMBER.
Once you are on the page showing the drawing with the 'exploded' assembly and the the relevant progressive number, just locate the part on the list in the bottom pane, move the mouse on the 'add to the cart' button without clicking. TheInternet Explorer Status Bar of will show a long string which is the link the button is pointing to. Locate the substring starting with DU. The number following the DU is the Ducati part number.
