Unfortunately there is very little information out there for these numbers and what information is available is not always very accurate. From 1930 to 1962 the VIN number was the engine number and was only located on the left case. The VIN was between 8 and 10 digits with the first 2 digits being the production year, the next 2 – 4 letters being the model designation and the last 4 digits being the production number Example: Year Model Production Number 49 FL 0001 1962-1969: From 1962 to 1969 the VIN numbers where pretty much the same as from 1930 to 1962, but if the production number had 4 digits the first digit would be odd during odd production years and even during even production years. If the production number had 5 digits the first two digits would be odd during odd production years and even during even production years.

Example: Year Model Production Number 66 FLHB -1980: From 1970 to 1980 the VIN number could be found on both the frame and the engine and would match exactly with the exception of a few months in 1979 which was due to an idea by the factory to make them different. The idea was quickly killed after law enforcement notified Harley-Davidson that it made the bikes look stolen. The production date range was from 1/9/1979 to 2/7/1979.

The VIN numbers affected are 43000H9 through 48199H9. The engine numbers where 10 digit numerical IDs. The VIN numbers of this era where 9 digit codes where the first two digits corresponded to the model code (see list below), the next 5 digits were the production numbers (always starting above 10,000) and the last 2 digits were the year code (see list below). From 1981 to present the VIN has been a 17 digit code located on the frame and abbreviated on the engine. In this VIN the first 3 digits are the world manufacturer ID (see list below), the fourth digit is the weight class (see weight class list below). The next two letters are the model designation (see list below), the sixth digit was the engine type (see list below), the seventh digit was the introduction period (see list below), The eighth digit was the VIN check digit which could be 0-9 or X, the next letter was the model year (see list below), the letter after that was the assembly plant (see list below) and the last 6 numbers were the production numbers.
