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.
