In the clutter and kitsch of American culture, few ideas survive the test of time. Consumer products that outlast their 15 minutes of fame are few and far between. The Fender Telecaster. The Louisville Slugger. PLAYBOY. Now you can add another to the list: the Harley-Davidson Sportster.

The Sportster has had a lasting impact on pop culture; it is a lens through which we can view five decades of popular culture. Somewhere along this timeline you became aware of motorcycles and specifically the Sportster. Shall we go for a ride?
