Harley Vin#s

Ever wonder what a Harley Vin# means?  (The numbers stamped on the frame of every Harley bike.)  Have you dazzled fellow bikers with the fact that every Harley Vin# starts with '1HD'?  Do they all actually start with '1HD'?  Well sure they do, if they were made in the United States.   Were all Harley's manufactured in the United States?  In fact, the '1' identifies the country of manufacture.  I'm not sure what the 'HD' stands for but if you study the tables below you can find out.
