The Excelsior Super X was a motorcycle made by the Excelsior Motor Manufacturing & Supply Company from 1925 to 1931, and the most famous Excelsior the company produced. It was the first American motorcycle of forty-five cubic inches, a mid-sized V-twin drawn up by Arthur Constantine, formerly assistant chief engineer at Harley-Davidson, to compete with the Indian Scout. Unlike earlier Excelsiors it had its engine and transmission in a single crankcase, with a helical gear driving the transmission directly, and it brought back leading-link forks. It replaced the sixty-one cubic inch V-twin and was seen as a better companion to the Henderson four. Indian enlarged the Scout engine in 1927, Harley-Davidson released its own forty-five in 1929, and production ended in 1931 when Ignaz Schwinn ordered his Excelsior-Henderson concern to stop making motorcycles.
