From 1952, Rumi built the SuperSport model of its twin for road racing with two Dell'Orto carburettors mounted vertically above the engine and its own design of bottom-link front forks. The racing Rumis were developed by former FN and Saroléa designer Salmaggi, whose tuned version of the 125cc Super Sport motor produced 8 HP at 7,000 rpm and was good for 72 mph.
