MAS was an Italian motorcycle manufacturer from 1920 until 1956. "MAS" stood, in the context, for "Alberico Seiling Motorcyles" (''"Motocicli Alberico Seiling"''). Seiling was an important Italian constructor who developed a variety of motorbikes between 1920 and 1922, and in 1922 started commercial production. His 173cc ohv model with an external flywheel proved particularly popular. He also produced a single cylinder 498cc ohv model, and from 1928 a twin cylinder model, also with 498cc of displacement. In 1937 an ohv model with a special cylinder head appeared, with a vertically mounted camshaft, the cylinder valves set horizontally in a separate chamber above the combustion chamber. The combustion mixture was premixed in this separate chamber. By excluding the valves from the combustion chamber itself it was possible to use a 15:1 compression ratio which was by the standards of the time very high. The motor was not a success, however. Seiling sold the MAS business to the Guidetti brothers in 1938. After this he continued to produced motor cycles in his own name (Seiling: A. Scoppio S.A.) and then, in 1939, he obtained finance to establish a new motorcycle manufacturing business under the name Altea. Altea produced a single cylinder ohv 198cc machine. However, this business ended in 1941 due to the general war which had by then broken out across most of Europe. ==See also == *List of Italian companies *List of motorcycle manufacturers 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「MAS (Milan)」の詳細全文を読む スポンサード リンク
