La célèbre moto américaine Excelsior fut produite par l'Excelsior Motor Manufacturing Company de Chicago (Illinois), de 1907 à 1931, à la fin sous l'appellation « Super-X ». Une V-twin de 1 000 cm3 (61 ci) fut ajoutée à la gamme en 1911, date à laquelle Excelsior fut rachetée par le fabricant de bicyclettes Ignaz Schwinn, et, en 1913, elle fut proposée avec une transmission chaîne-chaîne. En 1921, apparut une V-twin de 1 200 cm3 (74 ci), mais à cette date, Excelsior avait racheté les droits de fabrication de l'Henderson Four et les jours des grosses V-twin étaient comptés. Celles-ci disparurent en 1925, Excelsior préférant concentrer ses ressources sur la Four et la nouvelle V-twin Super-X 750 cm3.

Introduite en 1925, la Super-X conservait la distribution semi-culbutée de la « Big Twin » tout en revenant à la fourche avant à roue poussée utilisée sur les toutes premières machines. Pour le reste, elle fut majoritairement révisée en recevant un bloc moteur-boîte et une transmission primaire par pignons enfermés dans un carter en alliage léger. Un modèle Super Sport plus performant fut proposé et ces deux Super-X continuèrent avec peu de modifications sinon l'adoption d'un réservoir profilé en goutte d'eau pour 1929 juqu'à ce que Ignaz Schwinn arrête la production motocycliste au printemps 1931.

Cette Super-X restaurée est offerte avec son certificat de l'Automotoclub Storici Italiano.

    The famous American Excelsior motorcycle was produced by the Excelsior Motor Manufacturing Company of Chicago, Illinois from 1907 until 1931, latterly under the 'Super-X' brand name. A 61ci (1,000cc) v-twin joined the range for 1911, at which time Excelsior was acquired by bicycle maker, Ignaz Schwinn, and in 1913 was offered with all-chain drive. Two-speed planetary transmission and a leaf-sprung, Indian-style front fork were two of the following season's innovations. In 1921 a 74ci (1,200cc) v-twin appeared but by this time Excelsior had acquired the manufacturing rights to the Henderson Four and the days of the big v-twins were numbered. They were gone by 1925, Excelsior preferring to concentrate its resources on the Four and the newly introduced Super-X 45ci (750cc) v-twin.

    Introduced in 1925, the Super-X retained the Big Twin's F-head valve gear while reverting to the leading-link front fork used on its earliest ancestors. Elsewhere though, it was extensively redesigned, featuring unitary construction of the engine/gearbox and geared primary drive encased with an alloy casting. There was a higher-performance Super Sport model available and this pair of Super-Xs continued with few changes, other than a switch to a streamlined, teardrop-shaped fuel tank for 1929, until Ignaz Schwinn pulled the plug on motorcycle production in the spring of 1931.

    This restored Super-X is offered with an Automotoclub Storico Italiano certificate.
