Desmo service Ducati Streetfighter V4 S

I would like to buy a Ducati Streetfighter V4S. I’m just going through the offers and in an advertisement it says: “Desmo-Service” is done at 25000 km. Invoice available: 3.400,- € !!!! Can this be? A motorcycle inspection, which costs three and a half thousand otzen? I would simply leave the fingers of Ducati if that were almost true. LG Wolfgang
