km/h. In addition, the motorcycle looked like a clone of the junior models, with no hints of its high status. All of that generated low demand. In 1959, in an attempt to recover the poor sales of the 250, the company introduced a 16-hp 300-cc version. Army and police purchased a small number of these motorcycles in respective versions, but the overall sales were far from brilliant. As a result, the success hoped for was not realized with only 544 250-cc machines and about 500 300-cc machines being produced. Trying to completely rid the brand of the dubious fame of "fragile diamonds", the company's engineers completely redesigned the lubrication system by the 1959 season: they installed a high-performance oil pump, a centrifugal oil filter, and increased the volume of the pan. The main new MV Agusta 125 TRE advertising message was focused on its reliability and assured 100,000 km mileage without any problems, for which the model was nicknamed "Centomila" (English: one hundred thousand). In 1958, responding to the new Italian Road Law (Italian: Codice della strada), which closed highways for motorcycles of 125 cc or less, the company released a 150-cc version of the MV Agusta 150 RS (Rapido Sport). Its 10 hp engine accelerating the motorcycle up to 110 km/h, allowed it to stay in the stream (the most popular car of those times – the Fiat 500 – had a lower maximum speed). The same engine, detuned to 7 hp, was also installed on the small three-wheeled scooter Centauro. This machine with a load capacity of 350 kg already had a cab. In 1957, MV produced a cheaper version of the 175-cc engine with a camshaft located in the engine block. Later in 1959, this engine bored up to 232 cc became a heart of a new motorcycle – Tevere (English: Tiber). In fact, the 11 hp Tevere was a more dynamic and less affordable version of MV Agusta 150 RS, so the model was discontinued soon. But the 232-cc engine itself, equipped with forced cooling, was produced until 1968, to complete the Trasporto Tevere cargo scooter. A new family of ultralight (only 83 kg for basic version) Checca motorcycles debuted in 1960 to replace the Ottantatrè model. Technically Checca was similar to the 125-cc Centomila, but with a scaled parts. The basic version GT was equipped with an 83-cc 4 hp engine, an upper level GTE
