1954-MV-RAPIDO-SPORT

In the middle of the 1950’s 2-stroke motorcycle engines were falling from favor, and 4-strokes were gaining followers. MV capitalized on this by releasing the 125cc Rapido Sport in 1954. It was derived from the Turismo model. This model stayed in production until 1958. It was fitted with a single cilinder 9:1 compression ratio, air cooled engine that was rated at 7,5 HP, sufficient to propel the motorcycle up to 100 km/h The engine was mounted in a open tubular duplex cradle, essentally turning the casing into a frame structual member. It was painted entirely red and had a 150mm drum front brake. A strong, durable machine, it injected excitement into bread and butter motorcycle.
