Hello guys I have a question, Does anyone know how many 900ss models were brought into the U.S. in 1991--ie white frame & white wheels? and what may be the earliest vin # here in the U.S.? --Just wondering as I just acquired # 28. I am mainly a BMW guy and I have lots of documentation from BMW giving production numbers for the U.S & Europe models but Ducati who knows lol--The Italians dont keep the kind of records that the Germans do--but then who does. My 1991 900ss I do know was purchased in Italy by Renato who worked for Ducati.
