I can get most any bearing at my local john deere dealership that deals with farm machinery. Mind you, if it is spring planting or harvest time steer clear, as the parts guys have way enough on their plate dealing with us irate farmers with broken down machinery than having to take the time to cross reference your bearing for a toy- makes them kind of pissy to say the least. And you will need the bearing manufacturers part number- not the guzzi number.
