flat-twin petrol engine was released. Despite being designed as a portable industrial engine, the M2B15 was also used by several motorcycle manufacturers, including for the 1920–1923 Victoria KR1 and the 1920–1922 Bayerische Flugzeugwerke (BFw) ''Helios'' motorcycles. BMW merged with Bayerische Flugzeugwerke in 1922, and the BFw Helios became the starting point for the first BMW motorcycle. Released in 1923, the BMW R 32 used a flat-twin petrol engine, which was longitudinally-mounted to eliminate the cooling problems of the transversely mounted engine in the Helios. This engine with , resulting in a top speed of . At a time when many motorcycle manufacturers used total-loss oiling systems, the new BMW engine featured a recirculating

It was based on the ''R 32'' and used an overhead valve engine producing . The first single-cylinder BMW motorcycle was the 1925 ''BMW R 39'', which was BMW's smallest model and used a engine. It was not successful and was discontinued in 1927. The next single-cylinder motorcycle was the BMW R 2, which was released in 1931. It used a engine and could therefore be ridden in Germany without a motorcycle licence at that time. The lineage of single-cylinder motorcycles continued with the ''BMW R 4'' in 1932 and the ''BMW R 3'' in 1936. The BMW R 12 and ''BMW R 17'', both introduced in 1935, were the first production motorcycles with hydraulically damped telescopic

Unfortunately only 2638 motorcycles could be built before production was disrupted due to the War. Original bikes are now rare and highly sought after. Around 500 are known to survive today.

1939–1945

During World War II, the German military needed as many vehicles as it could get of all types and many other German companies were asked to build motorcycles. The BMW R 75 performed particularly well in the harsh operating environment of North Africa, partly due to the protruding cylinders of the flat-twin engine providing more effective cooling than other configurations which overheated in the sun. Shaft drives also performed better than chain-drives which were damaged by desert grit. The ''R 75'' inspired similar models from U.S. manufacturers, such as the

Eventually in 1952, after the Soviets ceded control of the plant to the East German Government, and following a trademark lawsuit, the East German company was renamed

, many of BMWs facilities had been badly damaged during the war, including the Munich factory which was in ruins. Initially, the terms of Germany's surrender forbade BMW from manufacturing motorcycles. In 1947, when BMW received permission to restart motorcycle production from US authorities in Bavaria, BMW had to start from scratch. There were no plans, blueprints, or schematic drawings because they were all in Eisenach. The first post-war BMW motorcycle in Western Germany, was the 1948 ''BMW R 24''. The ''R 24'' was reverse-engineered from the pre-war ''BMW R 23'' motorcycle with several improvements and powered by a single-cylinder engine. It was the only postwar West German model without rear suspension. In 1949, BMW produced 9,200 units and by 1950 production surpassed 17,000 units. Production of flat-twin models resumed in 1950 with the ''R 51/2'' model, which was followed by the BMW R 51/3 and ''BMW R 67'' twins in 1951, and the sporting BMW R 68 in 1952. Except for the ''R 68'', all flat-twin models came with "bell-bottom" front fenders and front stands. File:R51 Tank-badge 1.jpg , BMW emblem on a ''BMW R 51'' (1938–1940)


1955–1969

Motorcycle sales in Europe plummeted as the 1950s progressed, with three of BMW's major German competitors going out of business in 1967. In 1954, BMW produced 30,000 motorcycles. By 1957, that number was less than 5,500. In 1955, BMW began introducing a new range of motorcycles with Earles forks and enclosed drive shafts. These were the BMW R 50, the BMW R 60 and the sporting model BMW R 69 with . On June 8, 1959, John Penton rode a ''BMW R 69'' from New York to Los Angeles in 53 hours and 11 minutes, slashing over 24 hours from the previous record.

, increased success of the automobile division and the selling off its aircraft engine division. Changes in the motorcycle market saw BMW's last shaft-driven single-cylinder model, the BMW R 27, end production in 1967. Also, most of BMW's offerings were still designed to be used with sidecars. However, by the late 1960s, sidecars were no longer a consideration of most riders; people were interested in sportier motorcycles instead. The BMW R 50/2, R 60/2, and R 69 S were the last sidecar-capable BMWs, with the latter being the most powerful and desirable model. In the United States, sales of motorcycles were strong through the 1950s, in contrast to drastically declining sales in Europe.

1969–1982

The model range was entirely revamped in 1969 with the introduction of the BMW /5 range, consisting of the 500 cc ''BMW R 50/5'', the 600 cc ''BMW R 60/5'' and the 750 cc ''BMW R 75/5'' models. The engines were a complete redesign, with the crankshaft bearings upgraded from roller bearings to shell-type journal bearings (the type used in modern car engines). The camshaft was now chain-driven and located underneath the crankshaft instead of at the top of the engine, in order to lower the centre of gravity. An electric starter was available for the first time, although the traditional gearbox-mounted

er was also retained. The styling of the first models included chrome-plated side panels and a restyled tank. In 1973, the rear swingarm was lengthened, which improved the handling and allowed a larger battery to be installed. The introduction of the "/5" models coincided with production relocating from Munich to a new factory in

The "/6" model range consisted of the 600 cc ''BMW R 60/6'', the 750 cc ''BMW R 75/6'', the 900 cc ''BMW R 90/6'' and the sporting 900 cc BMW R 90 S. Other upgrades included a five-speed gearbox, brakes and the electrical system. In 1975, the kick starter was finally eliminated. Walker, Mick, ''How To Restore Your BMW Twin: 1955–1985'', pp. 20–22 In 1976, the BMW /7 range replaced the "/6" models. The 800 cc ''BMW R 80/7'' model was introduced, and the 900 cc ''BMW R 90/6'' and ''BMW R 90S'' models were replaced by the 1,000 cc ''BMW R 100/7'', ''BMW R 100S'' and ''BMW R 100RS'' models. The latter was a full-fairing design which produced and had a top speed of . Later variants of the 1,000 cc models included the ''BMW R 100T'' ("Touring"), the ''BMW R 100 RT'' and ''BMW R 100CS'' ("Classic Sport"). The 1978 BMW R 45 and BMW R 65 were entry-level 450 cc and 650 cc models that replaced the ''BMW R 60/7''. Later variants of the ''BMW R 65'' included the 1982 ''BMW R65 LS'', the sporting ''BMW R 65 S'' and the 1987 dual-sport ''BMW R 65 GS''.

1993–2003

Beginning with the BMW R 1100 RS sports tourer in 1993, BMW began to transition from engines with air-cooled cylinder heads ("airhead" engines) to oil-cooled cylinder heads ("oilhead" engines). The ''BMW R 100 RS'' also used "Telelever" front suspension (where braking forces are transferred horizontally to minimize "fork dive") and a stressed engine. Also introduced in 1993 were the single-cylinder BMW F 650 models, which was based on the

The "airhead" BMW R 80 GS and R 100 GS models remained in production until 1997, before being replaced by the newer "oilhead" models such as the ''BMW R 850'' series, the 1994–1999 BMW R 1100 R standard motorcycle, the 1994–1999 BMW R 1100 GS dual-sport, the 1996–2001 BMW R 1100 RT tourer, the 1998–2005 BMW R 1100 S sports, and the 1999–2004 BMW R1150 GS dual-sport. The K Series models, powered by a water-cooled inline-four engine, included the 1996–2004 BMW K 1200 RS sports tourer, the 1998–2009 ''BMW K 1200 LT'' luxury tourer, and the 2002–2005 BMW K 1200 GT sports tourer.

2004–2014

The revised K Series range of water-cooled inline-four cylinder models began in 2004 with the ''BMW K 1200 S'' a sport-tourer. The K1200S was primarily designed as a Super Sport motorcycle, albeit larger and heavier than the closest Japanese competitors. Other additions to the K Series range were the 2005 BMW K 1200 R naked bike and related 2007 ''BMW K 1200 R Sport'' semi-faired sport-tourer, and the 2006 BMW K 1200 GT sport-tourer. The engine capacity of the K Series was expanded to for the 2008 BMW K 1300 S sport-tourer, the 2009 BMW K 1300 GT sport-tourer and the 2009 BMW K 1300 R naked bike. In 2011, two six-cylinder models were added to the K Series range- the BMW K 1600 GT and BMW K 1600 GTL, the former intended as a sport-tourer and the latter as a luxury-tourer. The R Series range of flat-twin models was also updated in 2004, beginning with the BMW R 1200 GS dual-sport, which was powered by a new "oilhead" engine. This was followed by the 2005 BMW R 1200 ST sport-tourer, the 2005
