The first annual service (7500miles) for the V4 should be 2hours (20 Labor Units) plus oil, filter, washer. Unless it requires a Desmo intervention (7hr 36mins or 76 labor units). But yes your 7500 mile service is just an oil change plus a bunch of look over on the bike. I will try and get the actual work checklist if I can find it. As for the hours, Ducati transparent maintenance chart clearly lists how long all services are for each bike so as long as you go to a dealer they should quote you the appropriate hours (then multiply by the shops hourly rate). Total cost for the 7500mile initial annual service is usually around $300-$350; I suggest bringing your own oil to save a couple bucks.
