Mystery Motorcycle

The Cite de l'Automobile has a section of childrens pedal cars known as The Jammet Collection. Included in the exhibit was this motorcycle. It appears to be a gas engine motorcycle but it's child size. It's listed as a 1955 Harley Davidson but the Harley Davidson Museum in Milwaukee(I contacted them) does not have any information that H-D manufactured any toy sized motorcycles. Anybody know what it might be?
