An early racing motorcycle once owned by legendary Hollywood actor Steve McQueen is to be offered for sale by Bonhams at the International Classic MotorCycle Show in Stafford, UK, on Sunday 28th April.

The 1914 Indian Model F, estimated to realize between $ 40,000 and $50,000, is an example of a board-track racing motorcycle. These early purpose-built motorcycles lacked a clutch, throttle and brakes, and were push-started and run flat-out – often reaching speeds of up to 100mph – until the end of the race, when the rider would short the magneto to stall the engine.

The 1914 Indian Model F will join machines from three collections as part of a 240-strong offering of Pioneer, Vintage and Collectors' motorcycles at the Bonhams sale at the International Classic MotorCycle Show
