History of the BMW brand

Motorcycles under the BMW brand are produced by BMW Motorrad AG, a separate division of the famous German automaker. The BMW concern was formed by the merger of two small aircraft engine companies operating in Munich since 1913, which were created by Gustav Otto and Karl Rapp. The companies prospered thanks to large government orders for military purposes, and their merger occurred in order to increase production capacity.

In 1917, the company was registered under the name "Bavarian Motor Works" (Bayerische Motoren Werke, BMW), whose general director was Franz-Josef Popp. In the same year, the BMW emblem appeared, depicting a propeller against the sky. It is made in the national colors of Bavaria.

With the arrival of the talented engineer Max Fritz, a new era begins in the company. Fritz became famous even before the First World War. In 1917, after disagreements with the management of Mercedes-Benz, he got a job at BMW. At this time, the aircraft manufacturer was put on the brink of survival, because according to the Treaty of Versailles, the losing Germany could not build aircraft. It was necessary to repurpose it into producing other products or disappear from the industrial map. The company began producing engines for motorcycles.

Fritz prepared the first drawing of the motorcycle in December 1922, four weeks after receiving the order. Its feature was a boxer engine and a new combination of power components of the motorcycle.

He placed two cylinders transverse to the direction of movement, and not longitudinally, as was then common. This improved the cooling of the motor by air flow. The box was located next to the engine, and the drive came directly from the crankshaft, which was also located longitudinally. This combination of basic components is used in boxer engine motorcycles to this day.

The first BMW motorcycle was presented at the Berlin Automobile Exhibition on September 28, 1923. It was called R 32. From all points of view, the new product was of interest, and therefore was enthusiastically received by the public.

The model was equipped with a 494 cc engine developing 8.5 hp. Weighing 120 kg, it accelerated to 90 km/h.

From a technical point of view, the R 32 stood out not only for its revolutionary engine, the location of the power unit and the use of the crankshaft. The frame assembly system with two steel closed parallel contours was successful. The engine was located at the bottom of the frame, which lowered the center of gravity and made handling easier. The use of light alloys, dirt- and oil-proof springs and valve stems, a completely closed lubrication cycle - all this made the motorcycle easier to operate and made it stand out from its competitors. In addition, the public was captivated by the carefully thought-out design with strict, elegant lines and elegant colors.

It was an incredible success: despite the price of 2,200 marks, which was very expensive in those days, the motorcycles were sold out. Until 1926, the company sold about 3,000 units of the model.

Between 1923 and 1929, BMW motorcycles were purchased to supply the Moscow ORUD.

BMW R 32 (1923–1926)

The success of the motorcycle required confirmation on the race track. The company's young engineer, Rudolf Schleicher, dreamed of a racing career and believed in the R 32, which, however, needed a little reworking. This is how the R 37 model appeared with light alloy steel cylinder heads with overhead valves.

The motorcycle with a 500 cc engine developed 16 hp. On February 2, 1924, Rudolf Schleicher became the winner of the Mittenwalder Steig Hill-Climb race, setting a record time. After this, the bike won first places in many important German races, and BMW burst into the motorcycle world with a resounding title of leader.

However, the riders who saw the potential of the motorcycle did not stop there. In 1929, Ernst Henne set a new world speed record, accelerating the modernized R 12 motorcycle to 216 km/h.

In 1926, the R 32 was replaced by two new models - the R 42 and R 47. The engines of these motorcycles were redesigned. With the piston stroke length and cylinder diameter unchanged, the R 42 engine developed 12 hp. and received side valves, and the R 47 - 18 hp. and top valves.

In 1931, the R 2 model appeared with a 200 cc single-cylinder engine. cm and cardan drive of the rear wheel.

In 1935, BMW pioneered the use of a hydraulic telescopic front wheel fork, which replaced the leaf spring fork. The R 12 and R 17 models received this design.

BMW R 12 (1935–1942)

A year later, a new generation of motorcycle models appeared - R 5. These were the developments of Rudolf Schleicher, who equipped the machines with a 24-horsepower 500 cc engine. cm with a tunnel crankcase, two camshafts, foot-controlled gearbox, a tubular frame made of conical oval pipes, adjustable shock absorption of a telescopic fork and a footrest instead of the usual platforms of that time.

The model successfully competes with the best English bikes, surpassing them in ride comfort. In 1938, the R 51 entered the market, which received a vertical shock absorber for the rear wheel.

BMW R 51 (1938)

1937 went down in the company's history as the year Ernst Henne set the world speed record. On a motorcycle with a 108-horsepower 500 cc engine, he becomes the fastest pilot on the planet, developing 279.5 km/h. This record has not been broken for 14 years.

It is known that in 1930 the Soviet engineer P.I. Mozharov collaborated with BMW. The German motorcycle manufacturer expressed its gratitude for the fruitful work by giving him a personalized BMW R16 motorcycle, which then traveled along the roads of Russia.

In the 1930s, Germany became increasingly militarized. The government becomes the main buyer of BMW motorcycles. Single-cylinder models R 4 and R 35 were used for communications and training services. Equipped with sidecars, the R 11 and R 12 are used to supply food and quickly transport soldiers.

The German army command sets its own requirements for military motorcycles, the response to which is the production of the R 75 model. It was equipped with a 750 cc engine. cm, a double-action telescopic hydraulic fork and a frame that was constructed from combined modules with tubular connections and a central vertical section.

The transverse drive shaft of the sidecar was equipped with a limited slip differential, which allowed 420-kilogram motorcycles to carry a load of more than 400 kg. In 1942, BMW production was moved to Eisenach. There, more than 18,000 R 75 units are produced for military needs.

BMW R 75 (1941–1946)

In the pre-war years, the USSR was also interested in creating high-quality motorcycles for the needs of the army. It is known that in 1940 the People's Commissariat of General Engineering issued an order to develop a heavy motorcycle based on the BMW R71.

There are two versions of how the drawings of this model came to the USSR. According to one of them, with the consent of Stalin, 5 units of BMW R71 were smuggled, then dismantled and copied. The second version says that the German concern itself sold sketches of the bike, since the outdated model was supplanted by the R 75 developed specifically for the front. Be that as it may, the MMZ-M-72 was designed on the basis of the BMW R71, which was produced at the Kiev and Irbit motorcycle factories.

In the post-war years, BMW faced a severe decline. Many enterprises were bombed, some of the equipment was taken away by the Allies after the defeat of Germany. Initially, the company repaired American army equipment and produced instruments. In 1948, BMW returned to making motorcycles.

The revival was difficult, since all project documentation and almost all equipment were removed. The company rents machines from other companies and is seeking permission to manufacture the motorcycle. True, it was possible to produce only a single-cylinder model with an engine capacity of no more than 250 cc. cm.

The R 24 model, with a 12-horsepower engine with a centrifugal ignition system, was equipped with a four-speed foot-shift gearbox that used a ratchet mechanism. Weighing 130 kg, the motorcycle accelerated to 95 km/h.

BMW R 24 (1948–1950)

The motorcycle industry is growing rapidly again. Since 1950, BMW has brought back the two-cylinder engine to the market, but single-cylinder models are still the priority.

In 1951, the R51/2 model was released with a 24 hp engine equipped with overhead valves. Soon there will be a similar R51/3, as well as a 590 cc 26 hp R67. Then the R 68 comes out as a true sports bike, reaching speeds of up to 160 km/h.

BMW R 68 (1952–1954)

In 1960, the R 69 S model appeared, a motorcycle that reached speeds of up to 175 km/h and earned the title of the fastest production German motorcycle. With him, BMW has strengthened not only in the domestic but also in the foreign market. In the early 60s, demand in the German motor market fell, and most of the bikes produced were exported to the USA.

In 1969, BMW moved from Munich to Berlin, where aircraft engines were produced before the war, and machine tools after that. The beginning of the 70s is marked by a new wave of motorcycle boom. BMW enters the market with a line of motorcycles equipped with large displacement engines.

The most striking representative of the series of new products was the R 75/5 model with a 750 cc engine. It was equipped with a constant pressure carburetor, an electric starter, as well as lightweight suspension and chassis.

BMW R 75/5 (1969–1973)

In 1973, the R 90 S was released with an 898 cc engine. cm power 67 hp It accelerated to 200 km/h, was the first among the serial models to receive a fairing and captivated with its sporty appearance and impressive paintwork, which gave it dynamics even when parked. This motorcycle went down in history thanks to one of the most successful design incarnations.

BMW R 90 S (1973–1976)

In the same year, the first BMW exhibition in the USSR takes place in Moscow. It ended with the purchase by the Soviet side of the R60/6, BMW R75/6 and BMW R90/6 models for patrol services.

The next notable model was the R 100 RS with a 980 cc engine producing 70 hp. It was the first among production motorcycles to receive a full lining, which not only improved aerodynamics, but also protected the rider from wind and rain. This motorcycle became the founder of the class of sports touring motorcycles, in which BMW still dominates today.

With the company's involvement in off-road racing in 1980, the R 80 G/S was born by upgrading an off-road bike into a production enduro bike. After the release of this model, a segment of large enduros for touring is formed. The model was equipped with a single Monolever rear wheel swingarm and a large fuel tank. This motorcycle won the Paris-Dakar rally. Later, a revised version was released - R 100 GS.

BMW R 80 G/S (1980–1987)

In 1983, BMW motorcycles again made a real revolution. At its origins was the engineer Joseph Fritzenwenger, who invented a new technical concept embodied in the K series motorcycles. They differed in that the engine had a longitudinal cylinder arrangement and was located on the side of the frame. To the right of it was the crankshaft, and to the left were the overhead camshafts. In addition, four-cylinder engines received electronic injection for the first time.

Initially, the basic 90 hp BMW K 100 model was launched, which was soon supplemented by the K100RT with touring fairing and the K100RS with sports fairing. The latter reached speeds of up to 225 km/h.

BMW K 100 (1982–1992)

The series was completed by a model with a 741 cc three-cylinder engine, which was produced in two versions - the K75 without a fairing and the K75S with a small fairing.

In 1988, BMW was the first motorcycle manufacturer to offer ABS for motorcycles. In the same year, the first importer of BMW motorcycles appeared in Russia - Gewika Autoservice GmbH. Several motorcycles of the R100RS and R80G/S models were purchased for traffic police control.

In 1993, a new generation of boxer motorcycles was released, the first representative of which was the R 1100 RS model. It differed in that there were four valves in the cylinder head, which were controlled by a short pusher from the camshaft located just below. The model was equipped with a Digital Motor Electronics system, which, with a volume of 1085 cc. cm provided power of 90 hp. The motorcycle was equipped with a controlled catalytic converter, which helped keep the air clean.

BMW R 1100 RS (1993–2001)

A special feature of the model was that the supporting element was the engine with transmission and gearbox. The BMW R 1100 RS was wildly popular, received a large number of awards and once again confirmed BMW's reputation as a manufacturer of reliable and innovative motorcycles.

The year 1993 was marked by the appearance of the F series, which was the result of a collaboration between BMW and the Italian Aprilia and the Austrian Bombardier-Rotax. Its first representative was the BMW F 650 Funduro model.

It was the first single-cylinder bike since 1966 to be powered by a 650cc four-valve engine. The motorcycle was created to expand the circle of buyers and attract the attention of women.

BMW F 650 Funduro (1993–2001)

In 1993, official BMW dealers opened in Russia.

In the summer of 1996, the brand ends production of three-cylinder models and releases the K 1200 RS with a 1171 cc engine that helps accelerate to 130 hp. The model received a unique suspension and drive, setting new quality standards in the class of sports touring models.

In 2000, a “motorcycle with a roof” appeared - C1, which allowed the driver to abandon the helmet and protective clothing. It was equipped with a 175 cc single-cylinder engine and accelerated to 110 km/h.

BMW C1 (2000–2003)

In 2007, BMW bought one of the oldest motorcycle manufacturers in Europe - Husqvarna. This helps strengthen our position in the cross-country and off-road bike market. The first fruit of work with the new power is the G450 motorcycle with a 449 cc engine that develops 41 hp. With. at 7000 rpm.

BMW G450 (2007)

Today, BMW Motorrad produces motorcycles in Germany, as well as Austria, China and Taiwan. Most modern motorcycles are designed by David Robb, who was the company's chief designer from 1993 to 2012. The brand's motorcycles are presented in all classes, participate in the world's largest races and are popular all over the world.

In addition to motorcycles, the company produces helmets and equipment for motorcyclists. Responding to the demands of the modern world for environmental protection, BMW is constantly improving its technologies, developing a “green” direction.
