Debuting in 1960, the Checca was a lightweight motorcycle that was available in two displacements, 83 and 99cc. Three models were offered, the GT with a 83cc engine, the GT extra, which used a bored out version of teh 83cc engine, and the Sport GT, whose engine tuned to deliver slightly more power. This example’s single cilinder, 4-stroke angine was rated at 5,15 HP at 6000 rpm. The frame followed MV practice, being a mix of tubular front, and a steel pressed in the rear, as well as the engine being mounted in an open duplex cradle. The GT extra sold for 149.000 Lire. Production ended in 1969.
