If you are speaking Euro AE or US ES, note there are no top-out springs in the upside down forks as in conventional forks. It may be that when the front end rises to the limit of travel you'll hear a knock.
Otherwise, it could be natural noise from the brake rotors (floating rivets have clearance), brake pads, or loose fasteners. One place to look is the deflector shield under the lower triple clamp, or brake line clamps.
