1913 - 1915

In 1913, Excelsior stopped manufacturing the single-cylinder model. The two-cylinder model used an all-chain drive and remained a single gear machine. Excelsior was advertised as the only motorcycle with "complete control in the handlebars," with the right-hand grip controlling the throttle and the left the clutch.

Meanwhile, Henderson's 1913 model changed considerably; the engine displacement was increased to 64.9 c.i. (1064 cc).  A touring machine, the Henderson did not figure in track racing or hill climbing at first. However, it was a record-setting long distance and endurance competitor. In 1913, Carl Clancy became the first motorcyclist to circle the world, putting over 18,000 miles on his machine.

In 1914, Henderson offered a two-speed rear hub as an option, but otherwise the machine stayed the same. Excelsior also offered its first two-speed model, using a planetary gearset. Excelsior also returned to the single-cylinder market in 1914, offering the Lightweight, its first two-stroke machine, with a 15 c.i. (250 cc) engine. 

In 1915, Excelsior made major design changes in its existing models' performance and appearance. A new model was also introduced, the "Big Valve X." The Big Valve X had a 61 c.i. engine and Excelsior's first three-speed transmission. It was advertised as "The Fastest Motorcycle Ever Built."
