MV Agusta 99CC  Checca "Gran Turismo"


Derived from the “Checca 83” , the 99 used the 5,5 HP single-cilinder engine that had been improved to give the bike a better smoothness on mixed tracks. The frame continued the design used on the 83; a tunular front end and pressed-steel rear portion. The engine was nestled in an open duplex cradle, and the engine case acted as a structural member. Besides the change in the 99 Checca from the 83 was the paint finish. Total build was 1,977 units and production ended in 1969. In 1962, a 124cc version was released with the engine developing 6,5 HP.
