With Harley-Davidson’s recent introduction of its new Milwaukee-Eight engine, we thought it’d be fun to share this animated GIF with you showing the evolution of Harley-Davidson by generation from 1904 to the present. The GIF was pieced together by the staff over at GearHeads.
We figured we’d add a pictorial history of Harley-Davidson’s Big Twins over the years for good measure. Be sure to check out our “Harley-Davidson Launches 107” & 114” Milwaukee-Eight Engines” and “Our First Ride Impressions of Harley’s New Milwaukee-Eight” articles to learn more about Harley’s latest V-Twin or grab Issue 341 of American Iron Magazine that’s just hitting the newsstands for the full, in-depth overview.
