on one of these machines bored out to 196 cc in a 200-cc class race at Oulton Park in 1957. Around 200 of the model were manufactured between 1954 and 1957. The 175 cc engine became famous not only in road racing. From 1955 to 1958, MV also produced off-road racing motorcycles. But, perhaps, the most unexpected option manufactured in the same years was the trike Motocarro with a load capacity of 300 kg. Unfortunately the 175 cc family had a considerable drawback. In fact, the flip side of its advantages. After all, the motorcycle was designed by the racing engineer, who spent the best part of his life following the rule brilliantly formulated by Ferdinand Porsche: "The perfect racing car crosses the finish line first and subsequently falls into its component parts". Four-stroke 175-cc MV Agusta engines were distinguished by excellent dynamics at that time, but not durability. They were even given the nickname "Fragile Diamonds". In addition, the upper camshaft complicated the procedure for cleaning carbon deposits, which was required several times a season due to the quality of oil and fuel. Therefore, for the new 125cc motorcycle, which was supposed to replace two-stroke models, a simplified version of the four-stroke engine was developed, with pushrods operating the valves. The model debuted in 1954 in two versions: Turismo Rapido (6.5 hp) and Rapido Sport (7.5 hp). The chassis was similar to the 175-cc models (although the first units used a fully tubular frame, it was soon replaced by the same mixed design as the 175 CST), but a radical improvement appeared on the Rapido Sport was a hydraulically damped telescopic fork. Now Italian engineers were ready to take the next step: to increase capacity up to 250 cc. In the fall of 1956, the company introduced the 250 Raid. Its name seemed to hint: the toys were over, it was time to go on a long journey – at least across Europe (the name was chosen by voting among dealers of the brand). Technically, the motorcycle became the development of a 125-cc model: a single-cylinder four-stroke overhead valve (OHV) engine, a four-speed gearbox, a duplex frame closed through the crankcase of the power unit. Of course, everything was done much more solidly, so the dry weight of the motorcycle increased from 102 to 160 kg. As a result, 14 hp engine could hardly power this bike to 115
