In the postwar period, Germany's military-industrial complex was thoroughly paralyzed. The enterprises tried to find their own way.
The history of BMW motorcycles strongly depended on the development of the whole of BMW's further strategy, along with Popp and Friz, Martin Stolle, a high-class mechanic who before the war was the owner of his workshop in Munich, and later became a well-known BMW motorcycle designer, took part. His credit is the conviction of the company's managers to start developing new powertrains for motorcycles. In Germany the problem with personal transport was acutely felt, many companies tried to fix the situation in motor vehicles, but far from all the forces were able to produce engines independently.
In 1921, BMW introduced the first-born of the serial, opposed two-cylinder engine "M2 B15". The working volume of which was 494 cm3, and the power was only 6.5 hp.
One of the first wholesale buyers was the company "Victoria" completing these engines with its "KRI" models. Then the company Bayerische Flugzeugwerke AG began to buy. The organizer of which was in 1911 Gustav Otto.
The company Gustav Otto specialized only in the production of motorcycles. Then even the largest shareholder of BMW - Camillo Castiglioni put forward an offer to buy the entire company Gustav Otto, then use its opportunities for the serial production of motorcycles BMW.
In the 80s, absolutely new BMW motorcycles with liquid-cooled engines and fuel injection system went into the series. At first it was four-cylinder engines "K 100", 1983, 986 cm / 90 hp. Later in 1985 came a smaller three-cylinder motorcycle "K 75 C", 746 cc / 75 hp. An unusual layout is noticeable - thanks to the Mach Fritzenwenger patent the in-line engine was lying "on its side", which provided a reduced height of the power unit and the use of a cardan drive of the rear wheel.
Not stopping at what was achieved, the BMW concern in 1988 for the first time in the world - first in the family "K 100" and then in the family "K 75" - installed an anti-lock braking system in the drive of the brakes, and the next year on the motorcycles of the BMW 1000-cube family there appeared advanced electronics, a rear suspension of the "Paralever" type and four-piston brake calipers. In the same year, the "aerodynamic" K 1 model was introduced, which received a full fairing and a modernized four-cylinder, 1000-cc engine with four valves per cylinder.
In the history of motorcycles BMW marked a significant historic event which was on March 18, 1991, when the millionth motorcycle was assembled, the BMW model "K 75 RT" marked this event. The next year was the most successful for the company - in addition to the fact that the new BMW motorcycles "R100 R" and 1100-cubic "K 1100 LT" were introduced, sales of BMW motorcycles reached a record level, exceeding the figure of 35 thousand pieces.
The history of motorcycles BMW notes and debut in the fall of 1993 a completely new BMW motorcycle series "F 650" - single cylinder, liquid-cooled and with fuel injection. This is one of the most successful and recognized models of the company. Its latest version of the "F 650 CS" features cast 17-inch wheels, a cantilevered rear wheel mount and a main transmission with a toothed belt.
In 1994, the debut of the new "opposites" "R 850 R" and "R 1100 R" took place. In addition to the opposite scheme, everything else did not resemble the old family: four-valve dual-cylinder engines of air-oil cooling have camshafts in the cylinder heads, fuel injection system, optionally complete with ABS. In a completely different way than before, the chassis is made - to the crankcase of the power unit, which is the main bearing structure, both suspension brackets and all other units are attached.
