Ali..think those are off Richs old 851..if so there not decals, they are sprayed on (looked A1 though!!).
Im picking up a load of 851/888 factory clearance stuff on saturday morning and therell be loads of decals in ther if you can hang on till then..?
(Have a look through the attached list...theres quite a few 'ducati' decals..all the cagiva era that your looking for..)..
