In 1911, two brothers – William and Tom Henderson – established a motorcycle company in Detroit, USA, and their first bike was a longitudinal, in-line four. Rolling on a long 1650mm wheelbase, the Henderson Model A, according to company advertising, “allowed the rider to sit between the wheels, reducing road shocks to a minimum.”
This is my 1918 Model H, mechanically restored, all original untouched paint and parts. New tires only. It has the 1919 style rear wheel and brake with linkage.
The four-cylinder engine displaced 965cc and produced 5.1kW (7hp) and one of the Henderson’s most innovative features was the inclusion of a folding hand-crank for easy starting.
The Henderson brothers constantly upgraded their four. Between 1911 and 1917 the Henderson gained more gears, a shorter wheelbase, kick start, a mechanical oil pump and more displacement.
