Okay... my method needs 2 persons (normally me and my GF).
Step 1: Prepare a tool similar to the pictures attached. Steel tube should be 1.2m or longer, square end 1/2"
Step 2: Put one layer of electric isolation tape over the nut. This prevents from any damage or scratches to the nut
Step 3: One person sits on the bike, rear wheel is placed directly to a wall, floor shoud be concrete or tarmac
Step 4: Other person places tool and slowly open the nut (CCW for Ducati, CW for MV).
This way I could open really EVERY freakin nut without any damage to nut, axle or bearings. Simple and easy.
