In 1967, Laverda presented the two-cylinder 750 SF (Super Freni), the work of the engineer Luciano Zen.
However, in parallel with the touring machine with the latest technical refinements of the era, the brand concentrated on a motorsports-oriented clientele.
Starting from 1970, the 750 SF was supplemented by a competition consumer version, exclusively for private racers: the 750 SFC (Super Freni Competizione). While features like clip-on handlebars, sports fairing and a seat with seat tail were obvious choices, its distinguishing feature was large front and rear 230 mm double cam Laverda drum brakes, designed to absorb the excess energy produced by a redesigned engine. The valves were larger, while some parts were polished and lightened. Over 500 parts were different. The 750 SFC won every endurance race held in Europe between 1970 and 1974, except for the “Bol d’or”, where it nonetheless finished third in 1970 and second in 1971.
