Go here to get the Owner's Manual:
http://www.ducatiusa.com/services/maintenance/index.doMaintenance info starts on pp. 99. Keep in mind that service intervals are years and/or miles. In addition to belts, you'd like to see a few oil/filter changes, valve-check, fluids, and maybe plugs and air filter.
If those items haven't been done, plan on doing it or having it done if you pick up the bike. It may only have 1400 miles, but it's close to 4 years old. Not considering wear/mileage, tire shelf-life is about 5 years. If original, they'll be due for replacement in a year or so...
Good luck!
