Sinforiano Echeverria came to a business arrangement with the Iso parent company to manufacture the Iso in Spain, under licence.
Iso Motor Italia SA was formed in April 1951 and a 12,000 square metre factory was established in Carabanchel, Madrid.
The Isoscooter and the Isomoto were launched and had almost immediate sales success. 1954 saw the release of the Iso T19, a 19-inch wheel model with the same engine but with most of the chassis and components now built in Spain. A series of motocarro began that year, initially with 125cc engines and later with 150cc units. These were the Isocarro.
They began building a Spanish version of the Isetta, and in 1959 came to an arrangement with Borgward to build small trucks, vans and minibuses with four-cylinder four-stroke engines. This new venture also did very well.
Motorcycle sales for 1962 were 1,500 units, and for 1963 1,089. With the advent of cheap, light cars and the increasing national prosperity, Spain was experiencing a strong decline in motorcycle sales, as had most other European countries.
The Spanish company exported to Morocco and several South American countries.
In 1965 the Iso parent company closed, and Iso Spain was in difficulties. It was acquired by IMOSA.
