Gilera Motorcycles

In the early of motorcycle manufacturing, getting an was essential for budding engineers. At the of the twentieth century, one such was Guiseppe Gilera. The foundations for would become an internationally motorcycle manufacturing company at the Bianchi motorcycle company Guiseppe began his apprenticeship at the age of 15.

By the age of 22 (in Guiseppe had designed and built his motorcycle in Milan, Italy—a OHV machine.

As with many motorcycle manufacturers, Gilera in races to promote his machine, a local Hill Climb with his first bike. By he had established a small race which proved to be competitive and about a meeting that be the catalyst for Gilera motorcycles.

Early Investors

It was during a meeting in Italy that met a lawyer who was experiencing trouble his Harley Davidson. Guiseppe his extensive mechanical skills to fix the and in so doing impressed the lawyer for him to introduce him to some wealthy The net result was a new company manufacturing cylinder, and eventually twin side valve machines.

As the new grew, a new base was needed to the demand for Gilera machines and a new was found in Arcore, which is East of Milan. As the business other members of the Gilera were given key positions, but to a loyal workforce, he also interest free loans to to build houses in the area.

All of the early Gilera motorcycles in competition were modified bikes, but in 1924 an OHV push rod was introduced. This new design many modifications before it competitive in 1930/1 when a consisting of Rosolino Grana, Gilera and Miro Maffeis won the Trophy at the ISDT (International Six Day in Italy.

Over the years manufactured many different of machines, but one bike in particular had a effect on the company’s fortunes: the four cylinder racer of the

Inline Four

The origins of the 500 bikes can be traced back to the 1920s when two designers, Gianini and Piero Remor, a solution to a common problem inline four cylinder overheating. Other four machines of the time such as the used the inline design to the machines narrow, but inevitably the behind the first one got hotter as received less cooling air

The simple solution was to design an that placed the cylinders the frame. Although this ultimately limited the angle at the bike could be leaned before its cases touched the it had, none the less, efficient cooling.

The initial design is rumored to produced around 28 hp at 6000 but by 1933 after much (including the addition of a supercharger and cooling) the engine reputedly 60 hp at 8500 rpm. (Note: The using this engine at the was called the Rondine).

The Rondine on to finish first and second at a in Tripoli in 1935 and also set a record of 152 mph over a flying km. at the time were set either a standing start or at full as they entered a set distance, in case the kilometer.) Soon the record was set, the parent of Rondine, the Caproni Aircraft sold the design and machines to with the proviso that would also get the designer, to come and work for them.

Crank Main Bearings

the racing potential of the four machines, Gilera asked to concentrate on the engine’s known the crankshaft main bearings. The design formed the basis of the that set some fifty records and went on to win the World Grand Prix championship of with rider Umberto .

Interestingly, although the Gilera went on to become one of the most racers of all time, the factory made a street version. The of this is that the Japanese designs that eventually the markets in the 70s were clearly on the Gilera inline transverse
