9. 1903 Wasn’t Really the First Year of H-D Production
William Harley and Arthur Davidson finished one bike in ’03 and two more the following year. The first machine was two years in the making, with the assistance of a German designer named Emil Kroger. One of the next two prototypes was sold in 1904 to a Mr. Meyer, and after passing through four more owners in the following years, had reportedly logged 83,000 miles. The first year of “mass” production was 1905, when H-D manufactured eight motorcycles.
