usually you can find bearings, rollers, etc. at your local bearing supply house for cheap and usually in stock.
just take the old ones in with you.
there's nothing special about the bearings Ducati uses.
Uh, right. Hence me asking what the bearing numbers are. I don't want to have a beached bike while I wait for bearings to arrive. If I had the bearing #s, I could order them without knocking them out first.
