A Short History of the Gilera Marque
The Gilera family started in business in 1909 at Arcore near Monza, Guiseppe Gilera’s first machine being a 317cc side valve single.
At the end of WW1 the company was Italy’s main motorcycle supplier thanks to war contracts.
In 1936 Gilera bought the 1934-1935 Rondine (Italian for swallow), a four-cylinder 499cc supercharged and watercooled road racer designed by Carlo Gianni and Pietro Remor and produced by the Campagnia Nazionale Aeronautica (CNA) of Rome.
Count Bonmartini, a wealthy financier, had backed the Rondine racer (originally in sohc form) and engaged Piero Taruffi and Amilcare Rosetti as riders. Gilera developed the design, gaining many race successes and world speed records until the outbreak of war in 1939.
That season it was regarded as the fastest of European road racers, Dorino Serafini beating the supercharged BMWs at the German GP. Superchargers were banned post-war so in 1948, Remor designed a new 50 bhp/125mph aircooled dohc four (claimed weight under 300lb).
It became the dominant marque in the 500cc world championships of the fifties, taking the title in 1952 (Umberto Masetti), 1953, 1954 and 1955 (Geoff Duke) and 1957 (Libero Liberati). It is likely that Duke would have won the 1956 title for Gilera but for a six month ban imposed by the FIM.
Duke joined the Gilera Team in 1953 and quickly established rapport with the family-run factory. He persuaded Gilera to lower the machine and improve suspension and streamlining, in effect, 'Nortonising' it. Duke had won the 1951 500cc and 1951 and 1952 350cc world championships for Norton and was used to the qualities afforded by the Featherbed framed Manx models.
Among Gilera’s many classic victories, the one that stands out most is Glaswegian Bob McIntyre’s Senior Golden Jubilee Isle of Man TT win in 1957, when he was the first to lap the Mountain circuit at more than 100 mph. And on the fourth of eight laps (301.84 miles) he increased speed to lap at 101.12 mph on the dustbin faired model.
His average was another record - 98.99 mph. Earlier in the week he had won the Junior race on Gilera’s 350-4, setting new lap (97.42mph) and race (94.99mph) records over the seven lap (264.11 miles) race. By this time, the Gilera was giving out 60bhp at 10 000 rpm (claimed) but at the end of the season, Gilera pulled out of big time racing. Duke persuaded the factory to let him bring the racers out of retirement for the 1963 season and run the fours under the name Scuderia Duke (Duke stable). But by this time, Italian rivals MV had the upper hand at Grand Prix level.
In 1969 Gilera was taken over by Vespa’s parent company Piaggio. In 1994 the Arcore factory was closed (a Meriden style sit-in ensued) and production transferred to Piaggio’s plant near Pisa.
Today the Gilera name is prominent on the new breed of performance scooters and lightweight two and four-strokes.
