You can double-check your cam belt application by going to www.ducati.com, clicking on Bikes-Ducati Service-Parts Catalogs and then selecting your appropriate year and model. Download the parts catalog and look on image #8-10 for your appropriate belt. That's what I do for 1999-2007 bikes. Previous years -- call a Ducati shop.
