c.1917 BSA 4¼hp Motorcycle Combination
Engine no. 25737/28019
Introduced in 1905, BSA's first motorcycle used a proprietary engine and the firm did not offer a model entirely of its own design and manufacture until 1910. The first series-production BSA motorcycle was a 499cc (3½hp) sidevalve single, built initially with single-speed, belt-drive transmission and later on with a three-speed countershaft gearbox. Well engineered and equally well made, this first BSA proved an enormous success and changed little over the next few years, though for 1912 a two-speed hub gear was available together with an all chain drive model suitable for sidecar work. For 1914 the range was augmented by a 557cc (4¼hp) version featuring a strengthened frame and the new three-speed gearbox, which was designated Model K if fitted with chain-cum-belt transmission or Model H with fully enclosed all-chain drive.

Originally despatched to the French Army, this 'time warp' BSA was previously owned by the lady vendor's grandfather, then by her father, both of whom took great care of it. Believed last ridden in the late 1950s, the machine has been safely stored in a dry garage in the South of France since then. The BSA is believed never to have been restored and is described as complete and in excellent condition for its age. It comes with a French-made sidecar (not illustrated), various BSA catalogues, instruction manual (in French) and several boxes of spares. Accompanying documentation consists of miscellaneous parts/maintenance bills, assorted photographs, French registration papers, and correspondence (dated 1920) from BSA importers, Brown Brothers Ltd.

Footnotes

  • BSA 4¼ HP attelé, environ 1917
    Moteur n° 25737/28019

    Présentée en 1905, la première moto de BSA utilisait un moteur acheté à un sous-traitant et la marque ne proposa pas de modèle entièrement conçu et fabriqué en propre avant 1910. La première BSA de série était une monocylindre à soupapes latérales de 499 cm3 (3 ½ HP), construite à ses débuts avec une transmission à courroie à une seule vitesse, puis plus tard avec une boîte trois vitesses avec un arbre intermédiaire. Bien conçue et bien construite, cette première BSA connut un énorme succès et changea peu au cours des années qui suivirent, bien qu'en 1912 un moyeu à deux vitesses ait été proposé ainsi qu'une transmission par chaîne compatible avec l'installation d'un side-car. En 1914, la gamme fut élargie avec une version 557 cm3 (4 ½ HP) équipée d'un cadre renforcé et la nouvelle boîte à trois rapports qui prit le nom de Modèle K quand elle était équipée d'une transmission mixte chaîne-courroie ou Modèle H avec transmission par chaîne sous carter.

    Originellement vendue à l'armée française, cette BSA était la propriété du grand-père de la vendeuse, puis de son père, tous deux en ayant pris grand soin. Probablement montée pour la dernière fois dans les années 1950, la machine a été conservée sainement dans un garage sec, dans le sud de la France depuis. Cette BSA n'a vraisemblablement jamais été restaurée et est décrite comme complète et en excellente condition compte tenu de son âge. Elle est vendue avec un side-car de construction française (pas de photo), différents catalogues BSA, un manuel d'instruction (en français) et plusieurs boîtes de pièces détachées. La documentation se compose de diverses factures de pièces et d'entretien, d'un assortiment de photographies, de papiers d'immatriculation français et de lettres (datées de 1920) de l'importateur BSA, Brown Brothers Ltd.
