These top supports are tailored to fit Ducati 999s and 749s that do not accept spools. They are made to lift the bikes without interfering with axle removal.
These supports are not ideal for 2005 and later models that had the threaded holes to accept spools. If your swingarm is spooled, use either F0003-000, F0043-000, or F0028-000. Please call with any questions you may have.
