1931 Indian Four
Built as Indian Aces and Fours from 1927 to 1940, the Indian Four represents the end of an American motorcycle era which began with Henderson's 1911 in-line four. After selling his business to Schwinn in 1917, Henderson designed the Ace four-cylinder motorcycle. He was fatally injured on one in December 1922. In 1927, after a period of negotiation, Indian Motorcycle took over production rights to the Ace.
