Suzuki GT750S Vallelunga was based on 1973 GT 750 K' model. GT750 was water-cooled 3 cylinder 2 cycle monster, considered as ugly bikes back then but on the other hand, it has some cult like following and they are called "kettle" or "water-buffalo" because of water-cooled fin-less motor looking somewhat like a kettle. Vallelunga was a limited edition created by SAIAD, Suzuki’s Italian importer. Said, less than 200 units were made, and probably as few as 85, just so that the bike could qualify for the 1973 Italian championship races.
