A Brief History of the Marque
Founded by Naphtali Ollearo as a repair workshop, the Turin firm produced a 132cc Turismo model in 1926 with a three-speed transmission and a Sport model of 125cc. In 1927, the 132cc Comfort Lusso light motorcycle retains the general characteristics of the Turismo model with some cosmetic improvements and in 1929 a 175cc model was added. For the 1930 season the catalogue listed a 175 two-stroke with the cylinder tilted forward and a 175cc four-stroke ohv machine, and a Lady model with the top tube of the frame curved slightly downward.
For 1931 a 350cc Sirena model was released and in 1932 the shaft-driven 500cc Perla 500cc with four-speed gearbox made its first appearance.
The chassis, engine and drivetrain of the Perla was was further developed in 1934 as a three-wheeler, but unlike the Sirena a thing of beauty it was not.
By this time the firm had achieved considerable popularity, and had a contract with Fiat for the production of light trucks and vans based on the Fiat Topolino 500.
Post-war, in 1946 the factory built a two-stroke auxiliary motor of 45cc producing 1.25 hp at 4500 rpm which could be applied to the front or rear wheel of a bicycle. Then in 1948 new models, the Type 4 in 175 and 250cc versions, were added. In the following years they continued the production of the basic models, the DC micromotor 45, the three wheelers and vans, and a variety of motorcycles in displacements of 175, 250, 350 and 500cc.
1952 saw the end for Ollearo.
