The 1971 film On Any Sunday will likely go down in history as the greatest motorcycle documentary of all time. And while that’s due in part to the involvement of the legendary Steve McQueen, it’s also thanks to the brilliant work of the film’s director, Bruce Brown. Now, the director’s personal 1967 Triumph T20M Mountain Cub motorcycle is headed to the auction block.
While we wouldn’t quite say that this bike is responsible for the creation of On Any Sunday, there’s enough reason to think that the flick might not have happened without it. That’s because, riding high off his fame from surf documentary The Endless Summer, Brown traded in his Honda 50cc step-through for the Mountain Cub you see here. That trade-in led brown to enduro and dirt track racing, which inevitably led him to spark a friendship with McQueen, and the rest is history. Expected to go for $15,000-$20,000, this bike is a real and important piece of automotive history that’s ready for a new home.
