Henderson motorcycles were a brand of the "American Henderson Motorcycle Company" which was started in 1911, by Tom W. and William G. Henderson. The Henderson factory at 268 Jefferson Avenue in Detroit, Michigan, produced its first motorcycle in 1911, with its 934 cc in-line (IOE), or "inlet over exhaust" four cylinder motor.



A signature styling cue of the Henderson was its long wheelbase and correspondingly long gastank. In 1911 the first "Prototype" models were produced with a belt drive.

The 1912 Henderson Model 4 engine produced 7 horsepower.
