I came across this whilst doing some research for an engine I am building, not Ducati, and thought that it might be useful to post a link here as it might be of interest to someone. I think this tool might also work for Ducati head nuts etc. and the beauty is it will accept different spanners sizes (6mm to 19mm) and also Allen wrenches as well. It seems better than having a dedicated head tool that you might only use occasionally. I agree it costs more but I think you are more likely to get more use out of it in the long run.
