BMW began
production of motorcycle engines and then motorcycles after World War I. Its
motorcycle brand is now known as BMW
Motorrad. Their first successful motorcycle, after the failed Helios and
Flink, was the "R32" in 1923. This had a "boxer"
twin engine, in which a cylinder projects into the air-flow from each side of
the machine. Apart from their single-cylinder models (basically to the same
pattern), all their motorcycles used this distinctive layout until the early
1980s. Many BMWs are still produced in this layout, which is designated the R Series.
During the Second
World War, BMW produced the BMW R75 motorcycle with a sidecar attached.
Featuring a unique design copied from the Zündapp KS750,
its sidecar wheel was also motor-driven. Combined with a lockable differential, this made the vehicle very
capable off-road, an equivalent in many ways to the Jeep.
In 1982, came the K Series,
shaft drive but water-cooled and with either three or four cylinders mounted in
a straight line from front to back. Shortly after, BMW also started making the
chain-driven F and G series with single and parallel
twin Rotax engines.
In the early
1990s, BMW updated the airhead Boxer engine which became known
as the oilhead.
In 2002, the oilhead engine had two spark plugs per cylinder. In 2004 it added
a built-in balance shaft, an increased capacity to 1,170 cc and enhanced
performance to 100 hp (75 kW) for the R1200GS,
compared to 85 hp (63 kW) of the previous R1150GS.
More powerful variants of the oilhead engines are available in the R1100S and
R1200S, producing 98 hp (73 kW) and 122 hp (91 kW),
respectively.
In 2004, BMW
introduced the new K1200S Sports Bike which marked a departure for BMW. It
features an engine producing 167 hp (125 kW), derived from the
company's work with the Williams F1 team, and is lighter than previous K
models. Innovations include electronically adjustable front and rear
suspension, and a Hossack-type front fork that BMW calls Duolever.
BMW introduced anti-lock brakes on production motorcycles
starting in the late 1980s. The generation of anti-lock brakes available on the
2006 and later BMW motorcycles pave the way for the introduction of electronic stability control, or
anti-skid technology later in the 2007 model year.
BMW has been an
innovator in motorcycle suspension design, taking up telescopic front
suspension long before most other manufacturers. Then they switched to an Earles fork,
front suspension by swinging fork (1955 to 1969). Most modern BMWs are truly
rear swingarm, single sided at the back (compare with the regular swinging fork
usually, and wrongly, called swinging
arm). Some BMWs started using yet another trademark front suspension
design, the Telelever, in the early 1990s. Like the Earles fork, the Telelever
significantly reduces dive under braking.
BMW Group, on 31 January 2013 announced that
Pierer Industrie AG has bought Husqvarna for an undisclosed amount, which will
not be revealed by either party in the future. The company is headed by Stephan
pierer (CEO of KTM). Pierer Industrie AG is 51% owner of KTM and 100% owner of
