The part missing in the first picture is a push pin clip, an M8 size if I remember right.
The piece missing in the second picture is the rear pillion rider handle cover. Looking at the fiche I don't see that part listed separate unless it is sold with item 9 on this fiche which is the black colored piece right above it that also is called the rear pillion rider handle cover.
