NOT TO HIJACK SORRY>>>>>>
Well Bill since you so politely asked....
It would be a question of axle size and wheel width. Nothing more.
If I had your front forks and wheel I could do it for you.... or if you decided to fly or drive here I could show you.
Most of the time I just re-cut a whole axle to suit the job along with spacers.
Disc brakes are slightly harder to line up as disc diameter might not be the same as well as spacing from the hub. So then comes in the spacer factor on the discs. I usually make those as well. Providing they are the same diameter of course.
If not, then I'll find some that are and either fill in the existing mount holes and re-drill or figure something else out.
Note: Yamaha disc bolt patterns are almost exactly dead on for Ducati. Just need spacers to fit the calipers.
