Here’s a sweet (if dated) tidbit of Harley-Davidson history you don’t see every day: a late-1950s overview of the latest models of the day. Duo Glides, the new Sportster, Hummer, and Model 165 are all present and accounted for.
PerisCope Film has a great library of old film shorts on a ton of subjects, including more Harley stuff. If you’ve got some free time, their YouTube channel is totally worth some binge watching.
