dr. pietro remor designed a racing engine for mv agusta for the world motorcycle championship based on the gilera four-cylinder, for which he was previously responsible. the engine of the 1950 mv 500/4 cardano was inclined 30 degrees forward and had two overhead camshafts. between the 2nd and 3rd cylinder was the shaft for the spur gears. bore and stroke were 54 mm, and the inlet and outlet valves had a 90 degree between them. behind the crankcase, the gearbox was installed transversely. on the basis of this racing engine, mv agusta developed a production engine with lower compression, power and engine speeds to increase reliability. the production of the first motorcycle with transverse in-line four-cylinder was announced in 1950 by mv agusta, a prototype (500 tourismo) presented, but never went into production. in november 1965, the mv agusta 600 was finally launched at the milan motorcycle show.
