Don’s tribute bike is based on a 1974 Sportster, but there’s little to separate it technically or visually from the Sportsters used in the original 1969 show.

If you’re of a certain age, you’ll never forget Then Came Bronson, a short-lived TV show chronicling the adventures of Jim Bronson, a disillusioned but likeable young newspaper reporter out on a voyage of personal discovery.

Propelling Bronson from one episode to the next was his Harley-Davidson Sportster, transporting him through a kaleidoscope of fascinating characters and situations that both challenged and strengthened his gentle spirit.

Taken at face value, the travails of a social dropout played by a largely unknown actor riding around on a not-especially-good custom sportster doing improbable things doesn’t seem like much of a storyline.

But American society was undergoing tumultuous change, fueled by angst of a raging war, race riots, political assassinations, hippies and corporate cultures sucking the life out of ourselves or our parents. Craziness was all around. The time was ripe for a hero.
