A Milanese manufacturer, Gazzi was active from 1926 to 1932, initially producing auxiliary engines, pumps, oil recovery and transmissions for bicycles engines.

Their motorcycles had a 175cc engine, delivered in versions Turismo (SV), Turismo Lusso (OHV) and Sport (also OHV), along with a 250cc model.

During this time, they moved three times to different locations in Milan, always in the area of the canals.

The first business was at Rip. Gratosoglio 65 and called and Adolfo Gazzi & C.

The second was at in Via Meda 33, the company named Officine Meccaniche Gazzi.

Third was at via Montegani 7, the company named A.Gazzi & A.Bersani.

In 1929, single-cylinder vertical 4-stroke 175cc engines were built followed by 250cc overhead valve units, intended for sale to builders of lightweight motorcycles.

In 1930 they began producing their own light motorcycles with rigid frame and a single exhaust four-stroke engine with dry sump. .

The Turismo Lusso model had two exhaust pipes, and reportedly a hemispherical head with overhead valves. It was fed by a Binks carburetor, and had a Gazzi oil pump which returned the oil to the tank. Fired by a Bosch magneto, it had a Gazzzi three-speed gearbox with final drive by Renold chain. These were fitted to a cradle frame with Druid forks and a Terry saddle.

The wheels were 25 " x 3" with Hutchinson balloon tyres, and the saddle fuel tank capacity was 8 litres. Consumption was 2 litres per 100 km, oil capacity oil 1.5 liters and claimed top speed was 80 km/h.

In 1931 the frame was redesigned as was the engine which was inclined, sloper fashion, unlike its predecessors which had been vertical.

This model awarded Gazzi competition success, but alas the market had declined to the point where production of these fine machines was no longer viable.
