History
Iso of Bresso first made refrigerators and heaters (Isothermos), under the leadership of Renzo Rivolta. After the disappointing Furetto scooter came the Iso 125 in 1949. The engine was a split-single: a two-stroke with two pistons sharing one combustion chamber.
With about 7 hp it was stronger than many rivals, and reached 75 km/h. It weighed 93 kilos. Despite the high price it sold well. In 1957 Iso stopped making motorcycles and microcars to concentrate on sports cars.
