The most recent manuals are very hard to come by. Ducati sells them on a flash drive for big money and you get a whole collection of them. We've been looking for someone to share them with the community, but so far no one has. The most recent Monster service manual we have in the collection is for a 2014 1200. Maybe that will work?
I have one I got a couple years ago for my 2014. It says it is from ducati-manuals.com
An 886 page pdf. Has a lot of what looks like hyperlinks but don't work.
So, scroll scroll scroll to find what you want.
