The Indian Model O was a lightweight
Concept and design
The Model O was designed as an entry-level motorcycle to attract young riders.[1][2] It replaced the two-stroke single-cylinder Model K Featherweight, which was made in 1916 only.[2] In a layout similar to contemporary Douglas motorcycles from Great Britain, the Model O's flathead flat-twin engine was mounted with its cylinders along the line of the frame.[1][2] This added smooth operation to the Model K's existing light weight and practicality.[1][2]
The Model O had a cradle frame supporting the engine at the bottom of the crankcase, while the gearbox was mounted under the frame, below the rear cylinder.
Reception
The Model O was released in 1917, the year in which the United States entered World War I.[2] Indian diverted its efforts to selling motorcycles to the US military.[4] The appeal of lightweight motorcycles as transport was also eroded by the availability of mass-produced cars,[2] especially the Ford Model T, for which mass production began in 1913.[5] The Model O was not designed to appeal to enthusiasts, to which enthusiasts replied by calling the motorcycle the "Model Nothing". The Model O continued to sell poorly until 1919, when it was discontinued.[1][2]
Legacy
In 1919, the year in which the Model O was discontinued, Harley-Davidson introduced its Model W Sport Twin.[2][6] The Model W had a Douglas-like layout similar to that of the Model O, using a flat-twin engine with a transverse crankshaft and cylinders parallel to the frame.[2][6] Larger and more powerful than the Model O, the Model W had several innovations, including unit construction of engine and transmission, an enclosed drivetrain, and a coil-sprung trailing link fork.[2] The Model W sold well in its first year, but sales fell after that,[2] and it was discontinued in 1923.[2][6]

In October 1913, mass production of the Model T began at Ford's Highland Park, Michigan, Assembly Plant. Henry Ford had previously organized men and components to enhance Model T production, but the moving assembly line quickly improved chassis assembly speed from 12 hours and eight minutes to one hour and 33 minutes.
