The Indian Model O was a lightweight
The Model O was designed as an entry-level motorcycle to attract young riders. It replaced the two-stroke single-cylinder Model K Featherweight, which was made in 1916 only. 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. This added smooth operation to the Model K's existing light weight and practicality.
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. The rear wheel was rigidly mounted to a subframe bolted to the frame. The front suspension was initially a pivoting fork used on the Indian Single from 1906 to 1910 and on the Model K Featherweight. This was replaced during 1917 by a leaf-sprung trailing link fork.

introduced its Model W Sport Twin. 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. 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. The Model W sold well in its first year, but sales fell after that, and it was discontinued in 1923.
