A Century of Motorcycling | The 1970s

By Motorcyclist Staff, Photography by Motorcyclist Archives

No sooner had Americans gotten their heads on straight following the sordid ’60s, then they were presented with a whole new set of challenges: The first Energy Crisis and subsequent 55-mph national speed limit. Tricky Dick’s Watergate scandal and eventual resignation. Terrorism at the Olympics. And the “reality TV” that was Apollo 13. Yet there were good times, too: Star Wars debuted as a movie, not a missile defense system. And another film, On Any Sunday, helped make motorcycling mainstream.
