This spectacular racing Moto Rumi bought from the first owner, is an ultra-rare Super Sport model and an Italian masterpiece. Beginning in 1949, Moto Rumi built exquisite small-capacity flat two-stroke twins in many forms from 125cc roadster and scooters to 175cc and 200cc road racers and ISDT bikes, all of which were turbine-smooth and faster than anything else in their class.
From 1952, Rumi built the SuperSport model of its twin for road racing with two Dellorto 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 TPM and was good for 72 MPH. This ultra-rare 1953 Moto Rumi Super Sport TT Racer is a seldom seen rarity and is an example of Italian race engineering at its very best.
Officine Fonderie Rumi was originally founded by Donnino Rumi in 1914, and it made textile machinery in the 1920s. During World War II, the company then built two-man submarines and torpedoes, supplying the Italian Navy—hence its distinctive anchor logo. Like most manufacturers after the war, Rumi took on general engineering work in 1945, and then, in 1949, developed an exquisitely designed laid-down two-stroke twin-cylinder motor of 125cc with a 180-degree crankshaft and shapely unit-construction crankcase.
The company’s motors were quick and ultra-smooth, and it immediately participated in a wide range of competitions, including the ISDT (where the company won the Team Prize in 1954 with three golds), long-distance races (winning the Liége-Milano-Liége in 1954) and even Grands Prix (taking the first eight places in the 1954 Swiss Grand Prix).
