Gilera's Racing Heritage: From 1909 to the Grand Prix

The story of Gilera's involvement in motorcycle racing is a captivating narrative of innovation, ambition, and a relentless pursuit of speed. Founded by the visionary Guiseppe Gilera, the company's roots are firmly planted in the competitive world of two-wheeled motorsport. Guiseppe's early career, starting with an apprenticeship at Bianchi and a stint with the Swiss Moto Reve company, laid the groundwork for his future endeavours. However, it was in 1909, at the tender age of 22, that Guiseppe Gilera built his very first motorcycle of his own design in a small Milanese workshop. This initial creation wasn't just a display of engineering prowess; it was a winner, clinching victory in a local hill-climb event. This early success ignited a passion for competition, and by 1911, Gilera had established a modest but determined racing team, actively participating in numerous regional races. The brand's reputation for crafting capable machines began to grow, fuelled by Guiseppe's innate talent and his ability to attract both talent and investment. An encounter with a lawyer whose Harley-Davidson was experiencing issues, and which Gilera expertly resolved, proved to be a pivotal moment. The lawyer, deeply impressed by Gilera's mechanical acumen, introduced him to influential investors, paving the way for the formal establishment of the Gilera manufacturing company. Initially, the focus was on single-cylinder side-valve motorcycles, soon followed by twin-cylinder models, demonstrating a swift progression in their engineering capabilities. Guiseppe Gilera's leadership was also characterised by his generosity towards his employees, offering interest-free loans, which fostered a loyal and dedicated workforce, crucial for the demanding nature of racing development.

The Dawn of Gilera Racing Machines

The year 1924 marked a significant milestone with the release of Gilera's first pure-racing machine. This pushrod OHV (Overhead Valve) model, while initially underperforming, underwent extensive modifications. The dedication of the Gilera team paid off handsomely, as the improved racer secured victories in the 1930 and 1931 International Trophy races in Grenoble, showcasing the brand's burgeoning potential on the international stage. This period also saw Gilera making strategic acquisitions that would shape its racing future. In a move that would prove to be a masterstroke, Gilera acquired the rights to the revolutionary four-cylinder Rondine engine in 1935. This engine, originally conceived in the early 1920s by engineers Carlo Gianini and Piero Remor, was an innovative design. To address the cooling challenges inherent in inline-four engines, they mounted it transversely across the frame. The initial 490cc iteration produced a respectable 28bhp at 6000rpm, with advancements by 1928 boosting this to 34bhp. The strategic acquisition of the Rondine technology coincided with a period where motorsport was increasingly being used as a political tool, with nations like Italy, under Mussolini's regime, leveraging international racing success for national prestige, mirroring Germany's approach under Hitler.

The Rondine Era and World Records

The Gilera Rondine underwent a significant redesign in 1933. This evolved machine featured double-overhead-camshafts, water-cooled cylinders, and the crucial addition of a supercharger, which propelled its output to an impressive 60bhp at 8500rpm. The performance of this advanced racer was undeniable. In 1935, a Rondine shattered the 500cc-Class world record for the flying kilometre and mile, achieving a blistering speed of 152mph. This set a new benchmark for motorcycle performance and cemented Gilera's reputation as a leader in racing technology. The impact of the Rondine was long-lasting. By 1939, Gilera engineers had further refined the 500cc Rondine racer, modifying the crankshaft to increase power output to 80bhp at 9000rpm, enabling a top speed of 140mph. This iteration of the Rondine became the foundational platform for Gilera's racing machines for nearly four decades, a testament to its robust and adaptable design.

The Saturno and Post-War Innovations

Beyond the iconic Rondine, Gilera also developed a successful line of four-stroke production machines from the mid-1930s onwards. These models ranged from 100cc to 500cc. The most celebrated of these was the 1939 Saturno, notable for its integrated engine-gearbox construction. Powered by a 498cc OHV single-cylinder engine producing 22bhp at 5000rpm, it also featured advanced swing-arm rear suspension with twin, horizontal, coil springs. The racing variant, the Saturno San Remo, achieved considerable success in both national Italian and international competitions. However, it faced stiff competition from the multi-cylinder and overhead camshaft offerings of rival manufacturers. During World War II, Gilera produced the Marte for the Italian Army, a 498cc OHV single-cylinder machine with 14bhp, designed for use with a sidecar and equipped with shaft drive and a hand-operated transmission. The post-war era brought new challenges and regulations. With the ban on superchargers in racing motorcycles, Gilera responded by introducing a completely new 500cc racer in 1948. This machine featured innovative torsion bar and friction damper rear suspension. Despite these advancements, it experienced limited success, and a key engineer, Piero Remor, departed for MV Agusta. For the 1950 season, Gilera made further improvements, discarding Remor's rear suspension design and significantly reworking the engine's cylinder head. These revisions proved effective, with rider Masetti securing the 500cc World Championship title.

The Geoff Duke Era and Championship Dominance

The early 1950s were a golden age for Gilera in Grand Prix racing. While the 1951 title went to Norton rider Geoff Duke, Gilera, with Masetti at the helm, reclaimed the World Championship in 1952. Geoff Duke, finding himself sidelined by Norton, made the significant move to the Gilera team. His invaluable input led to crucial improvements in the handling of the Gilera machines. This collaboration bore fruit immediately, as Duke secured the 1953 World 500cc Championship. Gilera also clinched the manufacturer's title for the second consecutive year, underscoring their dominance. The period between 1953 and 1955 saw Gilera continue its winning ways. The engine underwent further redesigns during the winter of 1953-54, resulting in an increase in power to 64bhp at 10,500rpm. The 1954 and 1955 seasons mirrored the success of 1953, with Geoff Duke utterly dominating the field. For the 1956 season, the Gilera racer was revised again, incorporating a new 'dustbin' fairing and boosting power to 70bhp. However, a series of mechanical failures during key races prevented Duke from securing another title, which was ultimately won by John Surtees on an MV Agusta.

A Period of Transition and Revival

The year 1957 marked a turning point for Gilera. Guiseppe Gilera's son, Ferrucio, suffered a heart attack, leading to a loss of interest in the company and its racing activities. Despite winning the 1957 World Championship and manufacturer's title, Guiseppe Gilera made the difficult decision to withdraw the factory team before the start of the 1958 season. This withdrawal, alongside similar moves by Moto Guzzi and Mondial, left the Grand Prix scene open for MV Agusta, Ducati, and Morini. However, the formidable 500cc machines from 1957, which had been so successful under Geoff Duke, were not lost to history. They were resurrected in 1963 and, benefiting from advancements in tyre technology, proved to be still competitive. They raced for a single season before Gilera shifted its focus. The company began to de-emphasise its successful four-stroke single-cylinder line and pivoted towards motocross and off-road racing, often in partnership with specialist Elmeca. This strategic shift coincided with a decline in sales throughout the 1960s, and by 1968, the company found itself in receivership.

Integration into Piaggio and Modern Racing

A new chapter began in 1969 when Gilera became part of the Piaggio Group. This integration saw a renewed focus on the production of both road and off-road motorcycles. The early 1980s witnessed Gilera's innovative spirit re-emerge with the 125 Bicilindrica Cross. This was followed by the development of four-stroke, dual-shaft, single-cylinder engines in 150cc, 350cc, 500cc, 600cc, and 750cc capacities. The 750cc models achieved notable success, securing class victories in the Paris-Dakar Rally and an overall win in the Pharaoh Rally. In the highly competitive 125cc class, Gilera led the field with the powerful SPO2 and the futuristic CX125. Gilera made a significant return to the 250cc Moto GP World Championship in 1992 and 1993, further re-establishing its racing pedigree. Following this period, Gilera concentrated on the production of sport scooters. The company's return to road racing was marked in 2001, with an entry into the 125cc World Championship. This venture proved highly successful, with Manuel Poggiali clinching the 125cc World Champion title. The integration of Aprilia into the Piaggio Group further bolstered Gilera's racing presence, leading to a return to MotoGP in 2006, with Marco Simoncelli as the rider. Simoncelli's talent shone through, and he secured the 2008 MotoGP World Championship title in the 250cc class, adding another illustrious chapter to Gilera's storied racing history.
