If you know where the vehicle was originally purchased from and the date there is a possibility that Ducati Italy will be able to get you the information you require as they asked for my title details as they did not have them recorded (ie me as a new owner) and this differed from their own records.
Give them the engine number and if it's the original motor you may get lucky.
They can also update their own database aswell as they have a list of all original owners apparently???
Send an email to this lady and see if you get a response it wont be immediate but I have found them pretty exact and useful and they have always responded positively.
