If it looks like a Harley, checking the VIN is a way to make sure..
Since its founding in 1903 Harley-Davidson motorcycles have established an image of mystique and lore; bold revving engines, leather-clad bikers in sunglasses and chrome engines glistening in the sun. Beyond the surface however, Harley-Davidson is known for maintaining a high standard of quality for all its products. The vehicle identification number (VIN) on a Harley-Davidson motorcycle is not only an important part of registering legal ownership but also a way of verifying that the engine and frame are genuine Harley-Davidson items.
1. Locate the VIN. For bikes manufactured up to 1969, the identification is found on the left side of the engine case. There is no number on the frame.
2. Read the first two digits. This is the model year.
For example: 59FLH1234, is the year 1959.
3. Read the letters. The VIN on a Harley will have up to four of them. The letters represent the model.
4. Read the last four numbers. This number is the production number of the bike.
1970 – 1980

For example: 2C12345H5, the model code would be 2C.
