Indian was the largest manufacturer of motorcycles in the world during the early part of the 20th century, and the "Indian" brand was America's oldest motorcycle company, until its demise in 2003.
The company built its first production motorcycle in 1904, the diamond framed "Indian Single." The engine for the Indian Single was built by Aurora in Illinois. The Indian Single's deep red color became a signature of the brand. The single-cylinder motor was modeled after the de Dion-Bouton vélocipède engine, which produced 1.75-horsepower. The Indian Single could reach a top speed of 25 miles per hour.
Indian built its first V-twin engine in 1907. In 1916, Indian added the so-called "Powerplus" 1000 cc engine, which was a side-valve, 42 degree v-twin that was capable of a 60 mph top speed.
