not sure of the offset, but most ducati ones are 12mm, and they have 6 bolt holes like the superduke. watch out for anything from 749 and 999 onwards, they have 5 bolt holes and i'm not sure if the offset is different. some late monsters run the 5 bolt pattern rotors too.
There's a common brembo rotor for late SS' and a lot of monsters, it has gold alloy "snowflake" pattern carriers and stainless rotors, they're rubbish and warp really easily, avoid those.
