You have to measure the inside diameter of the frame holes on your Ducati and you can measure them individually.
The frame protectors are designed to cover a wide tolerance range. For example: If you determine an inner diameter of 21.8 you should prefer to use the 22mm frame protector, the dimension 22.5 you can safely order 22mm.
A tolerance range of -0.3 to +0.8 can easily be bridged.
The frame protectors seal the engine bolt against water via the O-ring.
Anyone who has ever dismantled an engine can report on firmly-corroded engine mounting bolts and swing arm bolts that seem to have grown together with the engine.
