Pre-1921
BMW began as a manufacturer of aircraft engines before the Armistice of WWI, the Treaty of Versailles prohibited the German Air Force so the company turned to Decision air brakes, industrial engines, agricultural machinery, tool boxes and furniture office and motorcycles and cars.
The origin of the BMW roundel
The circular blue and white logo of BMW or roundel is often invoked to describe the movement of a propeller plane, an interpretation that BMW adopted for convenience in 1929, which was made twelve years after the roundel was created. In fact, the emblem of the evolution Company logo Motorenwerke circular Rapp, whose company BMW has increased. The Rapp logo was combined with blue and white flag of Bavaria to produce the BMW roundel so familiar today.

In 1921, BMW began his long connection with a German invention known for 1886 that the Germans boxermoter (See Karl Benz and the flat-twin engines.) However, the first BMW motorcycle engine seems to have been copied by Max Friz, BMW's chief designer famous within four weeks after a British Douglas design. [Citation needed] This M2B15 boxer 19211922 manufactured by BMW for use as portable industrial motor, but is used largely by the manufacturers, in particular, Victoria Nürnberg Helios and motorcycles made by Bayerische Flugzeugwerke. Friz worked on car engines. [Citation needed] The design of a boxer motor is strongly related to BMW, but was used (not always by volume) for a number of other companies worldwide, including in his Honda Gold Wing 1975 to present.
BMW Bayerische Flugzeugwerke merged in 1922, inheriting from them the bike and Helios bike with a small two-stroke engine called Flink. In 1923, BMW's first "through the framework of" version of the boxer engine has been designed by Friz. The R32 has a 486 cc engine with 8.5 hp (6.3 kW) and a maximum speed of 95,100 km / h (60 mph). The form of engine and gearbox of one pin-up unit. At a time when many motorcycle manufacturers use a total loss lubrication systems, the new BMW has introduced a system Wet sump lubrication with a recirculating drip roller bearings. This system was used by BMW until 1969, when adopted the term "high pressure oil" bearing system based on gaps and narrow shell today.
The R32 became the foundation of all future power BMW boxer motorcycle. BMW oriented the boxer engine with the head protruding from each side for cooling as well as earlier British Bankers Association. Other motorcycle manufacturers cylinders aligned with the framework, one oriented toward a front wheel and one rear wheel. For example, Harley-Davidson introduced the Model W, a flat floor design oriented double back in 1919 and built until 1923.
The R32 also has shaft drive. BMW continues to use the drive shaft in all his bikes up the introduction of the Series F 650 in 1994 and the F800 in 2006 that was transmitted by a chain or belt system.
In 1937, Ernst Henne rode a supercharged 500 cc overhead cam BMW 173.88 mph (279.83 km / h), setting a world record was for 14 years.
During World War II Wehrmacht many vehicles needed as you could get all kinds and many German companies were invited to manufacture motorcycles. The BMW R75, a copy of a KS750 Zndapp a worse well in difficult operating environment of the African campaign North. Wheels of all kinds had been fairly well in Europe but in the desert of projection cylinders twin-engine plane for a better performance than configurations that heated the sun and the axis units better than the chain of units that were damaged by sand.
Such success the BMW engines of war that the U.S. Army asked Harley-Davidson, Indian and Delco to produce a similar bike near Valve BMW R71. Harley copied the BMW engine and transmission just to convert metric to inches and produces the driveshaft 750 cc 1942 Harley-Davidson XA.

The end of World War II found BMW in ruins. Its plant in Munich was destroyed by bombing allies. Eisenach plant was not. It was dismantled by the Soviets as reparations and return to the Soviet Union, where he was driving a motorcycle Irbit IMZ-Ural as often claimed. IMZ plant was supplied to the Soviets by BMW under the license before the start of the Great Patriotic War. After the war under the capitulation of Germany banned the production of BMW motorcycles. Most of the brightest engineers from BMW were taken to the U.S. and the Soviet Union to continue its work on jet engines which BMW produced during the war.
When the ban on the production motorcycles increased by controlled allies in Western Germany, BMW had to start from scratch. There were no blueprints, plans or drawings, because everyone was in Eisenach. Company engineers had to use surviving prewar motorcycles to copy motorcycles. The first post-war BMW motorbike in western Germany, 250 cc R24, took place in 1948. The R24 was based on the R23 before the war, and was the only post-war West German BMW no rear suspension. In 1949, BMW produced 9,200 units in 1950, production exceeded 17,000 units.
BMW boxer twins produced from 1950 to 1956 includes the 500 cc models R51 / 2 and 24 hp (18 kW) R51 / 3, the models of 600 cc 26 hp (19 kW), R67, 28 hp (21 kW) R67 / 2 R67 / 3 35 hp Sport (26 kW) 600 cc model R68. All models are equipped with a plunger rear suspension, front telescopic fork and the trees exposed chrome. With the exception of R68, all these come with twin front fenders "wrong" and faces.
The situation is very different in control Soviet East Germany, where BMW motorcycle plant in Eisenach was the production of R35 and only a handful of R75 motorcycles for repairs. This led to a BMW plant in Eisenach existing motorcycles between 1945 and 1948 and two motorcycle companies between 1948 and 1952. One was a BMW in Munich, Germany Western (later West Germany) and the other Soviet controlled Eisenach, East Germany (later the Republic East Germany), both with the name of BMW. Finally, in 1952. after the Soviets ceded control of the plant East German government, after a demand for brands such plant was renamed EMW (Eisenach Motoren Werke). Instead of blue and white medallion of BMW, the SEM uses a circle very similar red and black as its logo. No motorcycles made in East Germany after the Second World War were made under the authority of BMW in Munich, as there was no need for an occupation force for such authorization. After the collapse of the Iron Curtain SEM models have made their way to the United States. Sometimes we find that the owners of these bikes have replaced the towers SEM SEM with rounds of BMW in an effort to make them look like BMW models. [Citation needed] It is possible to find parts for motorcycles which R35 is restaurant today are part of the SEM and are BMW and many parts are interchangeable, so authentic identification quite difficult because of all the motorcycles BMW R35 held in Eisenach until 1952, when he became the SEM.
19551969
As the decade, 1950, sales fell by motorcycle. In 1957, three major German rivals BMW have ceased operations. In 1954, BMW produced 30,000 motorcycles. In 1957, this number was below 5,500. However, the end of 1950, exports 85% of BMW dual fuel motorcycle U.S. boxer. [Citation needed] At that time, Butler and Smith, Inc. is the exclusive importer of BMW U.S..
In 1955, BMW begun to introduce a new range of motorcycles with Earles forks and axes of the unit is closed. These are the 26 hp (19 kW) R50 500 cc, 30 hp (22 kW) 600 cc R 60, and 35 hp (26 kW) 600 cc R69 sports.
On June 8, 1959, John Penton rode a BMW R69 from New York to Los Angeles in 53 hours and 11 minutes, reducing more than 24 hours from the previous record of 77 hours and 53 minutes set by Earl Robinson in a 45 cubic inch (740 cc) Harley-Davidson.
While U.S. sales of BMW motorcycles were strong, BMW was in financial difficulty. With the combination of the sale of its aircraft engine and obtaining financing with the help of Herbert Quandt, BMW was able to survive. This change is due in part to the growing success of the automotive division BMW. Start of production of motorcycles, BMW had regular single-cylinder models. In 1967, BMW offered the last of them, the R27. Most bids BMW are not yet designed for use with a sidecar. This time-sidecar and not a consideration for most drivers, people are more interested sport motorcycles.
The 26 hp (19 kW) R50 / 2, 30 hp (22 kW), R60 / 2, and 42 hp (31 kW) marked the end of sidecar-capable BMW R69S. This time, the R69S is being the best example of the "/ 2" ("slash-two") series, because of the power output significantly higher than other models, among other characteristics of this design.
For models 1968 and 1969 alone, BMW exported to the United States, three "U.S." models. These are the R50US, R60US and R69US. In these bikes, there were no terminals sidecar attached to the frame and telescopic front forks are forks, which were then used worldwide in the bar-5 series from 1970 to 1973. Earles-fork models were sold simultaneously in the U.S. that the buyers had their choice of front suspensions.
19701982
In 1970, BMW has introduced a line of fully renovated 500-cc 600 cc and 750 cc models, the R50 / 5 R60 / 5 R75 / 5, respectively, and came with the "U.S." telescopic forks above. Engines have been comprehensively overhauled the old models, produce more energy and how electric start (although the launch function was included yet.) halfway through the model year 1973, a long wheelbase (LWB) was added to address these problems management before. These models are popularly known as the 1973 model. Most models with large tanks of 6 gallons, but some come with tanks 4 gallon. They are called "the toaster" models because of the similarity of the tank for a kitchen toaster.
The "/ 5" models have was short lived, however, be replaced by a new product line in 1974. In this year's 500 cc model has been eliminated alignment and an even larger 900 cc model was introduced, and improvements in the electrical system and the frame geometry. These models were R60 / 6 R75 / 6 R90 / 6. In 1975, the kick was eventually removed and a supersport model, the BMW R90S was introduced. In addition to "/" or "bar" models, other models like the Airhead G / S (later DP) and ST also spent more in the circles of BMW, while others favor some models earlier and / 5 "Toaster." Each has its own merits debate freely with enthusiasm. Later, different models of BMW K-bikes (1983) and oilheads (1993) includes technical innovations that made them more complicated, but many owners always opt for personalized service.
1994 BMW R100RT
In 1977, the product line has been moved to the directory "/ 7 "models. The R80 / 7 was added to the line. The R90 (898 cc) models," / 6 "and R90S models has increased its displacement of 1,000 cc and was replaced by the R100 / 7 R100S, respectively. These are the first size liters (1,000 cc) machines manufactured by BMW. 1977 was a outstanding year with the introduction of the first production of BMW motorcycles with a full fairing, the R100RS. This elegant model developed by wind tunnel testing, produced 70 hp (51 kW) and had a top speed of 200 kmh (124 mph). In 1978, the R100RT was introduced in the poster for the year 1979 as the first model of "dress" tourer, designed to compete in this market with the forthcoming Honda Goldwing.
In 1979, the R60 has been replaced by the R65 650 cc, an entry-level bike with 48 hp (36 kW), which has its own design framework. Because of their small size and improved geometry front and rear 18-inch (460 mm) wheels and a lightweight flywheel, it was a great handling bike could maintain older siblings, even fled when the right hand on the winding roads. BMW has added a game in 1982: R65LS, a "sport" model with a fairing quarter, two disc brakes front, stiffer suspension and different carburetors added 5 hp (4 kW). An abridged version of the race R65, R45 450 cc appeared in some markets. [Citation necessary]

In early 1983, BMW introduced a 1000 cc four-cylinder in line, water cooled engine for the market European K100. The K-Series comes with a simplified and distinctive rear suspension, a swing arm. (In 1985, the Boxer R80RT long bike ride Monolever rested on the rear suspension system and 1987 R100RT applicable).
In 1985, BMW was a version of 750 cc three-cylinder, this smoothed with another first, a counterweight shaft.
In 1986, BMW introduced an electrically adjustable windscreen on K100LT.
In 1988, BMW introduced ABS on their motorcycles. ABS became standard on all BMW models K. In 1993, the APA has been introduced in the first line Boxer BMW R1100RS. Since then it became optional for the rest of the range of BMW motorcycles.
In 1989, BMW introduced its version of a sport bike fairing full, the K1. The engine is based on the K100, but now, with four valves per cylinder. Production was about 100 hp (75 kW).
In 1995, BMW ceased production of the engines of an empty head, 2 valves, and provides online system boxer engine oilhead full 4-valve for the first time in 1993.
During this period, BMW has introduced a number of motorbikes, including:
R Series (dumb) – R65GS, R80GS, R100GS,
R Series (oilheads) – R850R/GS/C, R1100R/RS/RT/GS/S, R1150R/RS/RT/GS/S, R1200C

The R1200C, produced from 1997 to 2004, was entry only BMW motorcycle in the cruise market.
2004,
K Series
On September 25, 2004, BMW launched a radically redesigned K Series motorcycle, the K1200S, which contains a new four-cylinder, liquid-cooled engine of 123 kW (165 hp). The K1200S was primarily designed as a Super Sport motorcycle, albeit more bigger and heavier than its Japanese competitors. Shortly after the launch of the K1200S, the problems were discovered the new power plant designed to recover until early 2005 when corrective modifications have been place. Recently, a K1200S has set a land speed record for jet production of its kind in the Bonneville Salt Flats, exceeding 174 mph (280 kmh).
In the years following the implementation of the K1200S, BMW has also launched the Roadster K1200R K1200GT tourer naked sport, which began to appear in dealers in the spring (March-June) 2006. All three new K-Series motorcycles are based on the new inline four-cylinder engine, slightly different degrees different power. In 2007, BMW added K1200R Sport, a semi-faired sports touring version of the K1200R.
In October 2008, BMW launched three new models in the 1300 Series K cc, K1300R, K1300S and K1300GT. K 1300 models have an increased capacity of 136 cc engine, an increase power to 175 hp (130 kW) and a new exhaust system.
Two BMW R1200GS
R Series
In 2004, bicycles with the opposition, two-cylinder "boxer" engines have also been renovated. The new fighter is traveling less than 1200 cc, and is affectionately called a "hex" because the shape of the bottle. This engine is more powerful, and all bikes that use are lighter.
The first motorcycle to be launched with this updated motor bike was R1200GS dual-use. The R1200RT tourer and R1200ST Sport Tourer followed shortly behind. BMW then introduced kg 175 (390 pounds), 105 kW (141 hp) HP2 Enduro and 223 kg (490 lb), 100 hp (75 kW) R1200GS Adventure, each designed specifically for off-road and adventure tourism segment Motorcycles, respectively. In 2007, the HP2 Enduro joined the road biased HP2 Megamoto equipped with alloy wheels and smaller tires on the street.
In 2006, BMW launched the R1200S, which has a power of 90 kW (121 hp) at 8250 rpm.
F 800S
Series F
BMW also has attention been paid to the F series in 2006. It has reduced the price of the F650 current and F650GS Dakar F650CS &GS; and removed to make room for the F800 series program totally new. The new bikes are powered by a motor double parallel built by Rotax. They have a belt drive system, similar to the drive belt found on the F650CS today deceased, or chain drive. Initially, BMW has launched two new models of the F800 series, the F800S and F800ST sport bike sports tourer, the have been followed for F650GS and F800GS motorcycles double, since both use the engine of 798 cc despite different names.
G650 Xchallenge enduro
Series G
In October 2006, BMW announced the G Series all-terrain type co-developed with the Aprilia motorcycle. They are equipped with an improvement of only cylinder water-cooled 652 cc fuel injected engine producing 53 hp (40 kW), similar to that installed in the single-cylinder F650GS, and are equipped an automatic transmission chain. There are three models in the series, all produced by BMW by Aprilia at its plant in northern Italy Scorza, each focusing on a slightly different market:
G650 Xchallenge Hard Enduro Front 21 inch and 18 inch rear spoked wheels
G650 Xcountry encoder / adventure sports with 19-inch front and 17 inch rear wheels radio
G650 Xmoto Street Bike / Supermoto with 17-inch alloy wheels
In some markets, single cylinder F650GS has been renamed the G650GS.
HP2 series
The first was 175 kg (390 pounds), 105 kW (141 hp) HP2 Enduro, followed by the biased manner, "HP2 Megamoto with wheels alloy and smaller tires in the street in 2007.

Husqvarna acquisition
In July 2007, BMW has announced that it has signed a contract to acquire Husqvarna Motorcycles, including its production facilities and staff of the Italian manufacturer MV Agusta.
engine types
There are four lines of BMW motorcycles
F & G series single
Twins Series F
R Series
K Series
The series differ mainly by the type of engine that each uses.
F and G series single
F-Series, Single-cylinder BMW motorcycle was first launched in 1994 as as F650, and was built by Aprilia around a carburetor four stroke 650 cc, four valves per cylinder engine piston single, and the chain of transmission. The mission of the F 650 has been to provide an entry level BMW motorcycle. In 2000, the F650 has been redesigned, now with fuel injection, and called the F650GS. A terrain model based F650 Dakar was launched the same year. 2002 saw the addition of motorcycles Scarver "the F650CS the top line. The F650GS Scarver different variants, because it uses a drive system as opposed to a chain, had a much lower height of the seat and was designed for road use. All the 650 bikes produced from 2000 to 2007 uses a 652 cc engine built by Rotax in Austria and were built at BMW Berlin.
End of 2006, cycling of the G series of off-road motorcycles bias was launched with the same engine of 652 cc mounted on the F650GS, but the engine is no longer manufactured by Rotax.
In November 2007, G450X Sports Enduro bike launched a 450 cc single cylinder engine. The G450X contained several improvements technology in the field of Japanese motorcycle racing, but the most unique and significant was the use of a single pivot point for the pinion and swingarm. This unusual configuration has a transmission chain without settling very tense and acceleration squat deleted. The advantage the former save wear and allows the chain later, a disk geometry more consistent and fully available rear suspension travel during heavy accelerations.
Twins Series F
In mid-2006, F-Series has added two new motorcycles to the lineup, the Sports Tourer bike F800S and F800ST sport using both an engine of 798 cc parallel twin engine built by Rotax. Both bikes also feature a belt drive system similar to what was used in the F650. In 2007, the F650GS single cylinder has been replaced by two cylinders F800GS and F650GS models. This uses an enhanced version of 798 cc engine mounted in F800GS, marking a starting point for BMW naming convention.
R Series
Valve BMW four different covers.
two finned valve cover R68, 1954
Series I is built around a horizontally opposed boxer engine horizontally opposed. Since the engine is mounted a longitudinal crankshaft, cylinder head and protruding beyond the sides of the frame, so that the bike serial visual R distinctive. Originally R series bikes were at the head-cooled air ("air heads"), but is now produced only with oil-cooled heads ("oilheads" and "hexheads).
Photo BMW four different "bosses": How do you tell the different valve covers BMW ("heads") since 1970, apart? The "bridgehead" to cover in a 1973 R75 / 5 is top left.

K Series
BMW K series with water-cooled engines of three (K75) or four (K100, K1100, K1200, K 1300) cylinders. Until 2005, though currently in use in the K1200LT, the engine was longitudinal, lying on the left side with the butt of the left and right crank. Called the "Flying Brick" because the emergence of this provision. Sales did not meet the expectations of BMW, and production ceased with the model 1993. At the end of the career K-series, was 6921 units produced. In 2004, BMW introduced a transverse water-cooled 4-cylinder on the chassis and tilts 55 degrees forward. The BMW K75, three-cylinder models were produced from 1985 to 1996.
BMW K100 motorcycle engine of about 1986
BMW K 2004 1200GT style comes only two years
The first moto of the K series was the K100, which was introduced in 1983. It was followed in 1983 by the K100RS K100RT in 1984, and K100LT in 1986. In 1987, the K100 (Mark II) was introduced with ABS brakes, one on a motorcycle. In 1988 and until 1993 was BMW K1, ranging from a full version K 100 with the new style rear suspension Paralever. I had the Bosch Motronic fuel injection. At first, it costs 20,200 DM. Only 6,900 were produced.
In 1985, K75, three-cylinder was introduced. The K75C was the first model with this new engine. K75S was followed by the K75 and the Touring version K75RT. The last year of motorcycle production was 1996 K75.
In 1991, BMW increased the displacement of 100 to 987 cc of K, and the model designation became the K1100 (1097 cc). The K1100LT was first with the new engine. In 1992, the K1100RS is introduced, the year ending 8 production models K100. In 1998, BMW increased the size again to 1170 cc. This four-engine aircraft appeared on the K1200RS update. In 2003, the K1200GT fully faired, equipped with hard side bags and a bigger screen with electric height adjustment. K1200RS chassis has been widened and strengthened to luxury BMW K1200LT model, which is still in production in 2009.
K1200 is a 1157 cc engine later in the transverse line four, announced in 2003 and for the first time in 2005 K1200S. The new engine produces a healthy 123 kilowatts (165 c.), but the most striking detail, both visually and on paper, is its tilt forward 55 degrees and 43 cm (17 inches) wide, giving the bike in a very low center of mass, without reducing the maximum tilt angles. The engine used in the cons-K1200 K1200S, R, R Sport and GT.
In October 2008, BMW announced the new K1300GT, K1300R K1300S and models, all of which have greater production capacity of 1293 cc 175 hp (130 kW). The new engine produces maximum power 1000 rpm lower than the previous engine, more torque produced by the wing flap installed in the exhaust pipe.

Technology
BMW is a world leader in innovative technologies successfully suspension of the bike.
rear suspension on one side
The first suspension BMW Monolever published in 1980, then in the new R80GS / S rank if one universal card immediately behind the gearbox / engine. This system was then included in versions Modified Series K & R.
Paralever
Paralever is another step forward on one side of the BMW rear suspension (photo right). Is this the reaction torque coupled the suspension is compressed and spreads, avoiding the tendency to squat under braking and reduce speaking of tires on pavement. It was introduced in 1988 R80GS R100GS and motorcycles.
BMW invested in a revised Paralever R1200GS Adventure.
In 2005, with the introduction of the Hexagon ", BMW has invested Paralever and suggested that the standoff from the bottom of the upper drive shaft housing (Pictured right). This reduces underhang component and tends to increase ground clearance on the right lean.
It is believed [by whom?] That Paralever term developed because of the appearance of a parallelogram between the four elements that make up the rear suspension (rear-drive axle, transmission, and stimulate lower or higher). Other motorcycle manufacturers have proprietary versions of this system, including Arturo Magni Moto Guzzi MV Agusta and compact tree reactive.
Telescopic front fork
In 1935, BMW became the first manufacturer to form a damped telescopic hydraulic fork with their motorcycles. [Citation needed] Denmark's Nimbus was appropriate telescopic forks since 1934, but its release was suppressed until 1939. [Citation needed] BMW telescopic fork still used today in its Series F, Series G and HP motorcycles. K Series and R Series and use the front suspension Telelever Duolever.
Earles fork
Ernest Earles fork designed in English triangular one that resists lateral forces introduced by a sidecar (as opposed to the telescopic fork.) BMW Earles fork fitted to all models for 14 years from 1955. In this case, it was the year where the use of sidecars have peaked and quickly fell in most European markets (For example, the United Kingdom), but the system Earles fork was loved by pilots and solo. This causes the front end of the motorcycle stand brake to reverse the action of a telescopic fork. The strength of this design is sometimes a weakness for the rest of the bike, since transfers impact pressure of the structure where the damage is more difficult and costly to correct.
Telelever fork
Front Suspension BMW Telelever a R1150R.
The system was developed by Saxon-Telelever Motodd in Britain in the 1980s. The Telelever is a front fork, If the damper is located between and behind the two primary tubes attached to a Telelever arm.
This reduces unsprung weight and that decoupled wheel fork placement depending on the function of absorbing shocks – diving under braking and eliminate superior traction in situations braking. This system enhances comfort and stability while maintaining excellent handling and sports considerably.
Pictured from left shows the Telelever suspension unit. Both fork tubes do not provide cushioning or suspension. The front of the light gray "One Arm" can see happen on the engine side of the (hidden) spacer between the fork tubes.
Duolever
The upper part of the suspension Duolever
In 2004, BMW announced the K1200S, which incorporates a new front suspension is based on a design by Norman Hossack. BMW has acknowledged this, but not paid Hossack copyright. BMW named its new front suspension Duolever. Since 2009, the K1300S is Duolever, K1300R and K1300GT.
The official BMW Motorrad Duolever explanation is as follows:
The suspension of the front wheel is kinematically Duolever considered a square seal, in which two bonds forged behind allocated through Mobile bearings in the structure. These links are raking which visually resemble a conventional phone company too rigid fork wheel torque aluminum molds cast permanently. A central strut, which adjusts the suspension damping is related to the lower of the two links to flight, and builds cons frame.
Control of the joint trapeze mounted on the head and the wheel support is coupled with the handlebars. This reflects the cut set of movements direction. Therefore, the design Duolever unlike telefork not need fixed and sliding tubes. At the same time, separates the steering and damping Telelever more consistent than would appear.
The advantage of this suspension of the front wheel of the motorcycle market today is its rigidity torsion. The BMW Motorrad Duolever front wheel suspension is not influenced by negative forces in the same manner as conventional telefork also that the half-pipe fixed and rotary and longitudinally during swing / bounce and direction. His two links back to absorb the forces caused by the swing / bounce and maintaining stable support wheel. Therefore, the exclusion of any suspension of the front wheel is twisted and very precise. driver's steering commands are converted directly and comments the front wheel is transparent in all driving conditions.
An anti-diving film is also performed, as the Telelever, because of the link end bearing arrangement. While a strong telefork conventional braking maneuvers during jounce largely or accidents, suspension travel has Duolever enough of this situation, the pilot can still brake very late corner, but the direction is stable.
The obstacle avoidance maneuver of the front wheel when driving on uneven surfaces can be converted into Duolever similar to the behavior of a telefork. Under low unsprung weight and small separatist forces of the system, this translates into the characteristics of the most sensitive response and comfortable.

Fans of vintage BMW motorcycles are increasingly rapidly in number. As time passes, that BMW enthusiasts account "Vintage" is changed. BMW pre-war are the most coveted, as demonstrated during the Auction Gooding & Company in California in October 2006, when a BMW R32 1925 sold for $ 77,000. [Quote] Need

Piston-frame models for 1950 are the next most coveted and then "Slash-2" variants from 1955 to 1969. In recent years, the "Slash-5" Model 1970, a 1973 years model began to join this exclusive club. History of BMW models have grown rapidly, fueled in part by auctions half motorcycle auction large U.S. takes place every January in Las Vegas, Nevada.
Review for the treatment of their condition varies vintage motorcycle and tastes of their owners. The first choice tends to be to preserve the original machine if you're in pretty good condition. second is limited to restoring, maintain the original fabric as possible. Third, when a machine is in poor condition, is known as field monitoring of the restoration. In the latter case, the bike is completely disassembled and each piece is restored and then reassembled the bike is high time possible to the original design but with modern parts parts, such as stainless steel or plated parts that had not been sown. At the end of the restoration is the "Contest" in which only the original restoration parts are used and the work is done with an obsession for originality in every detail. Unlike many other brands of motorcycles, parts for old BMWs, while expensive, can be obtained from sources in Germany and the United States.
There are several BMW motorcycle Professional Conservators at work in North America and Europe. Two members of American organizations, Vintage BMW Motorcycles BMW Motorcycle Owners Club and Veterans of the United States is dedicated to the preservation of vintage BMW motorcycles.
