As the 1950’s rolled on, it was clear that the typical MV Agusta consumer possessed a proclivity towards sport riding. To satisfy this buyer preference, MV engineers tended to design motorcycles that were superb sport bikes, but weren’t ideal commuting vyhicles. Production of the handsome 175 Supersport (CSS) started in July 1954, and its engine was fitted with needle valve springs, magneto volano ignition with a trembler on the left, a rec-counter drive, an ”EARLES” front fork, and 2.75- 19 tires. A dellorto SS25 unit handled carburation, and fuel capacity was 14 litres. Such a bike was rare in its day, and much rarer today.
