Nagamoto Motor Research Institute (Hamamatsu,Asada City), 1953-56
長本発動機研究所
Nagamoto Motor produced something a bit unique for its time - a liquid cooled SV 4 stroke ! These were marketed under the Life ( ライフ ) brand. The cooling was via thermo-syphon, so no fan or radiator and was offered in a 150cc version in 1953 and a 225cc version in 1954. Some sources show the company folding in 1954, but the Japanese History of Motorcycles site shows 1956.
