The 125 TR was produced from 1954-1958 in about 40.000 units. The price varied from 180.000-200.000 Lire depending on the model and year of production. The first examples of the Turismo Rapido (TR) had a fully tubular frame, even at the rear. This feature was soon abandoned. In 1954 the 125 TR was built with box section rear frame components following the pattern established for the other models. The bike was usually painted black with a red fuel tank. Many people felt that the 4-stroke engine had more status than a humble 2-stroke thus MV installed a 125cc single-cilinder 4-stroke engine that generated 6,5 HP at 6,000 rpm. Maximum speed was 90 km/h and with a fuel tank capacity of 12 liters and consumption rate of 2 liters per 100 km, long-distance rides were easily possible.
