on the production model MV 98. By that time, the capacity of 98 cc was no longer relevant in racing world, which had become more organized and moved on to the classic 125, 250 and 500 cc categories. In 1947, MV Agusta went to the Milan Trade Fair with a number of new features. In addition to a "Luxury" version of the 98, the two-cylinder, two-stroke 125 cc bikes and the 250 cc single-cylinder 4T bikes appeared. Technical characteristics of the MV Agusta 250 Turismo were regular for those times. Its single-cylinder engine with compression ratio 6.0:1 produced 11 hp at 4,700 rpm allowing the motorcycle to speed up to 110 km/h.

More motorcycle manufacturers were competing in the inaugural world championships that were held in Switzerland, Netherlands and Italy. The Mondial 125 cc DOHC design dominated the 1949 season. In the end of 1949, Count Domenico Agusta invited two key professionals from Gilera – Piero Remor, who designed Gilera's four-cylinder 500cc racing motorcycle, and Arturo Magni, who was the chief mechanic of the Gilera's racing team.
