Legendary motorcycles: the Honda CB750 (1969) that made the British tremble 

The Honda CB750 didn't just revolutionize large-displacement motorcycling: it redefined the very notion of the modern motorcycle. When it appeared in 1969, this affordable four-cylinder offered a front disc brake, flawless reliability and performance previously reserved for the elite. Its worldwide success shook the British old guard and paved the way for the reign of Japanese road bikes. More than just a model, the CB750 became the symbol of a new era in which technology combined with passion.

The birth of the myth: Honda shakes up the large-displacement engine

At the end of the 1960s, the world motorcycling landscape was dominated by British industry, with brands such as Triumph, Norton and BSA offering twin-cylinder bikes renowned for their torque and retro charm. However, a new wind is blowing in from Japan. Honda, already a key player in the small and medium-displacement segment thanks to its reliability and technological mastery, decided to strike hard in 1969: the birth of the Honda CB750. With its in-line four-cylinder engine and front disc brake, it was poised to redefine the standards of large-displacement motorcycles for decades to come.

To understand the impact of the CB750 from the outset, we need to look at the context of the time. Motorcyclists were increasingly looking for performance, but also reliability and everyday practicality. Japanese manufacturers, who had first conquered the market with small, economical motorcycles, were now moving up in displacement. Honda, buoyed by its success in competition (notably in Grand Prix racing), developed a production engine derived from its racing know-how: a transverse, air-cooled 4-cylinder with a displacement of around 736 cm³ and a power output of almost 67 bhp. A respectable figure for 1969, especially when accompanied by a smoothness of operation and ease of use unheard of in the category.

But the real revolution isn't limited to the block. The Honda CB750 is one of the first production motorcycles to be equipped with a front disc brake, a major step forward in terms of safety and braking. While many competitors still use drum brakes at the front, which are less durable, the CB750 offers bikers more precise control, while reinforcing its image as a "modern" machine. Its lines, too, break with purely British tradition: the fuel tank has a more angular shape, the rear-view mirror is integrated into the handlebars, the dashboard features two round, easy-to-read meters, and there are, of course, those four chromed exhaust pipes that join to form two mufflers on each side (in the "four pipes" version).

Fans of large-displacement motorcycles were quickly won over. In the U.S., the CB750 embodied the promise of a beast of the road capable of devouring kilometers on the freeway while remaining docile in town. In Europe, it's a technical UFO: can you really offer a high-performance, reliable four-cylinder at a competitive price? Honda succeeded, almost turning around in a few years a market where British models were already starting to show signs of fatigue. Trade magazines praised the CB750 as a major turning point in the evolution of production motorcycles. Its overall balance, technological standing and relatively affordable price made it an object of desire for the motorcyclists of the day, eager for something new.

Why the CB750 is the world's first superbike

Many models have boasted innovation or outstanding performance, but the 1969 Honda CB750 truly made history through three fundamental aspects: mechanical revolution, cultural impact, and bold yet simple design.

First, there's the mechanical revolution. The transverse four-cylinder already existed in competition, but it was rare to find it on a mass-market machine. With the CB750, Honda made this engine layout accessible to a broad customer base. The result is impressive: over 200 km/h top speed, linear acceleration and great flexibility thanks to quadruple carburation. Right from the start, the smoothness of the four-cylinder engine is seductive. Gone are the excessive vibrations typical of big British cars, replaced by smoother running and superior overall reliability. The front disc brake is another key feature, giving the CB750 a considerable safety advantage at the time.

Secondly, the cultural impact is immediate. The CB750 is often described as the first production "superbike". It's not just a question of numbers, it's also a question of status: on the road, the presence of its four pots and gleaming engine arouses fascination and curiosity. Amateur racers, seeing it as a machine with sporting potential, didn't hesitate to enter local competitions or take part in endurance races with slightly prepared versions. Many celebrities, particularly in the United States, adopted the CB750 as a symbol of modernity. At the same time, it became a medium for customization: the "chopper" or "café racer" trend took hold of it, and all kinds of variations flourished, from the artisanal bobber to the minimalist cafe-racer preparation. In this respect, the CB750 becomes a "universal" model, the ideal basis for any project.

Finally, the design is both sober and striking. If we compare the 1969 CB750 with some of its competitors of the time, we notice a more "geometric" approach: a rectangular tank with soft edges, triangular side covers, and of course that double exhaust system with four tailpipes. The bike is imposing, but without excess, and the chassis remains fairly simple: a tubular steel frame, telescopic front forks and twin shock absorbers at the rear. Ergonomics are designed for mixed use: comfort as a duo, luggage carrying and a relaxed riding position, making it more versatile than a purely sporty machine. This versatility, combined with its "no nonsense" look, makes it timeless. Even today, many tuners and restorers draw inspiration from its lines, often preferring a streamlined version to accentuate the beauty of its 4-cylinder.

The timeless heritage of a four-cylinder revolution

It's impossible to talk about the CB750 without mentioning the enormous influence it had on the motorcycle industry. With the launch of this daring "4-legged", Honda ushered in a new era. Kawasaki quickly responded with the 900 Z1 (then the 1000 Z1-R), Yamaha developed its own 4-cylinder XS, and Suzuki followed suit with the GS. The era of the "big British sisters" was already on the wane, and the CB750 accelerated this transition: Japanese reliability, competitive pricing and comfort won out over the aging charm of the British brands. Little by little, the revolution was underway, and the expression "Universal Japanese Motorcycle" (UJM) was born to designate these "all-purpose" motorcycles, which borrowed the same mechanical framework: in-line 4-cylinders, double rear shock absorbers and a functional design.

In cultural terms, the CB750 established itself in the 1970s as the motorcycle for the "everyman" who wanted a touch of sportiness, but also everyday comfort. It also served as the basis for extravagant preparations: the legendary choppers developed in the USA, with their "ape hanger" handlebars and extended forks, frequently used the CB750 engine, judged more reliable than American V-twins for long roads. In Europe, it gave rise to café-racer variations: the rear loop was shortened, a wristband handlebar was fitted, and an attempt was made to imitate the look of racing motorcycles. In all these configurations, the CB750 shines for its adaptability and sturdiness.

As for its sporting achievements, the CB750 is helping to democratize competition for amateurs. In endurance races, some private teams dared to enter this machine, proving that a mass-market motorcycle can withstand hours of racing without failing. While the CB750 didn't always dominate the racing scene against more specialized motorcycles, it nonetheless remains emblematic of an era when you could almost "buy the Sunday bike at the corner store" and turn it into a weekend racing machine.

From an industrial point of view, the CB750 was a milestone: it definitively propelled Honda to the rank of major large-displacement manufacturer. Subsequent generations (CB750 K1, K2, K6, etc.) refined the recipe, with improvements to brakes, suspension and finish. Later, other models in the Honda range (CB900F, CBX1000...) perpetuated this spirit of reasonable performance, while regularly innovating. Japanese competitors, inspired by the success of the CB750, also developed their 4-cylinder ranges, leading to the triumph of Japanese motorcycles on the world market in the 1970s and 1980s.

Finally, the CB750 community lives on. Clubs dedicated to the "Seven-Fifty" exist on every continent. Collectors are particularly interested in the first series, sometimes called "Sandcast" (whose crankcases were produced by sand casting), which have become rare and highly prized. CB750 restorations highlight just how far ahead of its time this bike was, and how relevant its design remains today, more than fifty years after its release.

Ultimately, the 1969 Honda CB750 is one of the most influential motorcycles in history. It embodies a mechanical revolution, a cultural icon and an industrial turning point that ushered the motorcycle world into the era of the Japanese four-cylinder. Its commercial success, reliability, customization potential and relative affordability have forged its legend, earning the admiration of several generations of motorcyclists. For many, it remains the "mother of all superbikes", and continues to thrill those who dream of a four-wheeler singing along country lanes, or a retro-chic silhouette striding through the city with class and confidence.
