The ring sets you will be supplied for any Ducati built after the early '80s will only be suitable for Nikalsil bores.
Replacing the bores on a late-model Ducati with cast-iron sleeves would be a backwards step.
When these large bore sizes were replicated in cast-iron in the early days they tended to develop 'chatter marks'.
I believe a lot of these 'stretched' designs from Ducati (large bores, short strokes and high revs) are only permitted by the use of the Nikalsil bore lining.
It has reduced friction and better heat dissipation than the old iron-sleeve technology.
