History of BMW motorcycles

Motorcycle history

BMW engine opposition and the transmission unit in a R 32.

Pre-1921

BMW began as a manufacturer of aircraft engines before the First World War armistice, the Treaty of Versailles prohibited the German Air Force so the company turned to making air brakes, industrial engines, agricultural machinery, toolboxes and office furniture and then to motorcycles and cars.

The origin of the BMW roundel

The circular blue and white BMW logo or roundel is often alleged to describe the motion of a propeller plane, an interpretation that BMW adopted for convenience in 1929, which was actually twelve years after the roundel was created. In fact, the emblem of evolution Company Logo Motorenwerke Rapp circular, which the BMW company grew. The Rapp logo was combined with blue and white colors of the flag of Bavaria to produce the BMW roundel so familiar today.

In 1921, BMW began its long connection with a 1886 German invention known to Germans as the boxermoter (see Karl Benz and flat-twin engines.) However, the first motor BMW motorcycle appears to have been copied by Max Friz, BMW's chief designer famous in four weeks after a British Douglas design. [Citation needed] This boxer M2B15 19211922 manufactured by BMW for use as portable industrial motor, but is used largely by motorcycle manufacturers, in particular, Victoria Nürnberg and Helios motorcycle made by Bayerische Flugzeugwerke. Friz was working on car engines. [Citation needed] The design of a boxer motorcycle is strongly linked 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 Helios motorcycle and bicycle with a small two-stroke engine called Flink. In 1923, BMW's first "through the framework of" version of the boxer engine was designed by Friz. The R32 had a 486 cc engine with 8.5 hp (6.3 kW) and a maximum speed of 95,100 km / h (60 mph). The engine and gearbox form a single unit pin-up. At a time when many motorcycle manufacturers use systems total loss lubrication, the new BMW presented a recirculating wet-sump lubrication system with a drip roller bearings. This system was used by BMW until 1969, when it adopted the "high pressure oil" bearing system based on shell and narrow gaps still today.

The R32 became the foundation for all future BMW motorcycle boxer power. BMW oriented the boxer engine with the head projecting on either side for cooling as well as earlier British ABC. Other motorcycle manufacturers cylinders aligned with the framework, one oriented toward a front wheel and one to the rear wheel. For example, Harley-Davidson introduced the Model W, a flat floor double aft oriented design in 1919 and built until 1923.

The R32 also features shaft drive. BMW continues to use the drive shaft in all its motorcycles until the introduction of the F 650 series in 1994 and the F800 in 2006 which was transmitted by a chain or belt system.

In 1937, Ernst Henne rode a supercharged 500 cc overhead camshaft 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 asked to build motorcycles. The BMW R75, a copy of a Zndapp KS750, a worse well in the harsh operating environment of the North African campaign. Bikes of all kinds had done reasonably well in Europe, but in the desert of cylinders protruding twin-engine plane for a better performance than configurations that heated by the sun and the axis units perform better than the chain of units that were damaged by sand.

So successful were the BMW as machines of war that the U.S. Army asked Harley-Davidson, Indian and Delco to produce a similar bike to the side of the valve BMW R71. Harley copied the BMW engine and transmission simply convert metric to inches and produced the shaft drive 750 cc 1942 Harley-Davidson XA.

The end of World War II found BMW in ruins. Its plant outside Munich was destroyed by bombing allies. Eisenach plant was not. It was dismantled by the Soviets as reparations and sent back to the Soviet Union, where he was to ride a motorcycle Irbit IMZ-Ural as commonly alleged. IMZ plant was supplied to the Soviets by BMW under the license before the start of the Great Patriotic War. After the war terms of the surrender of Germany banned the production of BMW motorcycles. Most BMW's brightest engineers were taken to the U.S. and the Soviet Union to continue his work on jet engines which BMW produced during the war.

When the ban on the production of motorcycles rose controlled allies in Western Germany, BMW had to start from scratch. There were no plans, blueprints or schematic drawings, because everyone was in Eisenach. Company engineers had to use surviving prewar motorcycles to copy the bikes. The first post-war BMW motorcycle in western Germany, a 250 cc R24, occurred in 1948. The R24 was based on the R23 before the war, and was the only postwar West German BMW no rear suspension. In 1949, BMW produced 9,200 units and 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 600 cc models from 26 hp (19 kW), R67, 28 hp (21 kW) R67 / 2 R67 / 3, and sport 35 hp (26 kW) 600 cc R68 model. All these models come with plunger rear suspension, front telescopic fork, and chrome shafts exposed. With the exception of R68, all these twins came with front fenders "bell" and faces.

The situation was very different in Soviet-controlled East Germany, where BMW motorcycle plant in Eisenach was producing only R35 and a handful of motorcycles R75 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, West Germany (later West Germany) and the other Soviet controlled Eisenach, East Germany (later the Democratic Republic German), both with the name of BMW. Finally, in 1952. after the Soviets ceded control of the plant to East German government, after a demand for brands this plant was renamed EMW (Eisenach Motoren Werke). Instead of blue and white medallion BMW, the SEM uses a very similar red and black circle as its logo. No motorcycles made in East Germany after the Second World War have been 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 many SEM models have made their way to the U.S.. Sometimes we find that the owners of these motorcycles have replaced the SEM SEM rounds with rounds of BMW in an effort to make them look like models of BMW. [Citation needed] It is possible to find find restored motorcycles parts of which R35 today are part of the SEM and are in BMW and in many parts are interchangeable, so authentic identification quite difficult because of all the motorcycles BMW R35 occurred in Eisenach until 1952, when he became the SEM.

19551969

As the decade progressed, 1950, motorcycle sales plummeted. In 1957, three major German rivals BMW went out of business. In 1954, BMW produced 30,000 motorcycles. In 1957, that number was less than 5,500. However, late 1950, BMW exports 85% of dual fuel motorcycle boxer United States. [Citation needed] At that time, Butler and Smith, Inc. was the exclusive U.S. importer BMW.

In 1955, BMW began to introduce a new range of motorcycles with Earles forks and axes of the unit is closed. These were the 26 hp (19 kW) R50 500 cc, the 30 hp (22 kW) 600 cc R 60, and 35 hp (26 kW) 600 cc sports R69.

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) of Harley-Davidson.

While U.S. sales of BMW motorcycles were strong, BMW was in financial trouble. Through the combination of the sale of its aircraft engine division and obtaining financing with the help of Herbert Quandt, BMW was able to survive. The change was due in part to the increasing success of BMW's automotive division. From beginning of its production of motorcycles, BMW had regular single-cylinder models. In 1967, BMW offered the last of them, the R27. Most bids BMW are designed not yet used with a sidecar. For this sidecar time and were not a consideration for most drivers, people are more interested in sports motorcycles.

The 26 hp (19 kW) R50 / 2, 30 hp (22 kW), R60 / 2, and 42 hp (31 kW) marked the end of R69S BMW sidecar-capable. This time, the R69S is being the best example of the "/ 2" ("slash-two") series, due to significantly higher power output than other models, among other features unique to this design.

For model years 1968 and 1969 alone, BMW exported to the United States three "U.S." models. These were 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 subsequently used worldwide in the bar-5 series from 1970 to 1973. Earles-fork models were sold simultaneously in the United States as buyers had their choice of suspensions front.

19701982

In 1970, BMW introduced a completely revamped product line of 500 cc, 600 cc and 750 cc models, the R50 / 5, R 60 / 5 and R75 / 5, respectively, and came with the "U.S." telescopic forks noted above. The engines were a complete redesign of the models old, produce more energy and how electric start (although the launch function has been included yet.) part way through the model year 1973, a long wheelbase (LWB) was added to address these management problems before. These models are popularly called 1973 models. Most models come with large tanks of 6 gallons, but some come with 4-gallon tanks. These are called "the toaster" models because of the similarity of the tank to a kitchen toaster.

The "/ 5" models were short-lived, however, being replaced by a new product line in 1974. In that year the 500 cc model was removed alignment and an even larger 900 cc model was introduced, along with improvements in the electrical system and frame geometry. These models were the R60 / 6 R75 / 6 and R90 / 6. In 1975, the kick starter was finally removed and a supersport model, the BMW R90S was introduced. In addition to "/" or "bar" models, other models like the Airhead G / S (later, GS) and ST have also devoted following within the circles of BMW, while others favor certain models anterior and / 5 "toasters." Each has its own merits debate freely with enthusiasm. Later, the different models of BMW K-bikes (1983) and oilheads (1993 a) includes technical innovations that made them more complicated, but many owners still elect for personal service.

1994 BMW R100RT

In 1977, the product line was moved to the "/ 7" models. The R80 / 7 was added to the line. The R90 (898 cc) models, "/ 6 "and R90S models had increased its displacement of 1,000 cc and was replaced by the R100 / 7 R100S, respectively. These were the first size liters (1,000 cc) machines manufactured by BMW. 1977 was an exceptional year with the introduction of the first production of BMW motorcycles with a full fairing, the R100RS. This elegant model designed through wind tunnel testing, produced 70 hp (51 kW) and had a top speed of 200 km / h (124 mph). In 1978, the R100RT was introduced in the poster for the 1979 model year as the first "dress" tourer, designed to compete in this market with the forthcoming Honda Goldwing.

In 1979, The R60 was replaced by the R65 650 cc, an entry-level motorcycle with 48 hp (36 kW), which had its own design framework. Because of their smaller size and better geometry front and rear 18-inch (460 mm) wheels and a lightweight flywheel, it was a great handling bike that could easily maintain and even older siblings fled when the right hands on winding roads. BMW added a game in 1982: R65LS, a "sport" model with a quarter fairing, dual front disc brakes, stiffer suspension and different carburetors added 5 hp (4 kW). A short version of the R65 race, the 450 cc R45 appeared in some markets. [Citation needed]

BMW R1150RT

In early 1983, BMW introduced a 1000 cc in-line four-cylinder, water cooled engine for the European market, K100. The K-Series comes with a simplified and distinctive rear suspension, a single-sided swingarm. (In 1985 the Boxer bike tour R80RT traditionally been driven Monolever this rear suspension system and in 1987 R100RT any).

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 the K100LT.

In 1988, BMW introduced ABS on their motorcycles. ABS became standard on all BMW models K. In 1993 ABS was introduced first in line at the BMW Boxer R1100RS. Since then it has become available as an option the rest of the range of BMW motorcycles.

In 1989, BMW introduced its version of a full fairing sport bike, the K1. 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 empty-headed 2-valve engines and moved boxer engine line system oilhead full 4-valve for the first time in 1993.

During this period, BMW introduced a number of motorcycles including:

R Series (idiots) - R65GS, R80GS, R100GS,

R Series (oilheads) - R850R/GS/C, R1100R/RS/RT/GS/S, R1150R/RS/RT/GS/S, R1200C

F Series - F650 Funduro, Strada F650ST, F650GS, F650GS Dakar, F650CS Scarver

Series K - K1, K100, K100RS, K100RT, K75, K75C, K75S, K75RT, K1100RS, K1100LT, K1200RS, K1200LT, K1200GT.

The R1200C, produced from 1997 to 2004, was the entry of BMW Motorcycles only in the cruise market.

From 2004,

K series

On September 25, 2004, BMW launched a radically redesigned K Series motorcycle, the K1200S, which contains a new inline four-cylinder, liquid cooled engine with 123 kW (165 hp). The K1200S was primarily designed as a Super Sport motorcycle, albeit more larger and heavier than Japanese competitors. Shortly after the launch of the K1200S, the problems were discovered with the new power plant designed to recover until early 2005 when corrective changes were put in place. Recently, a K1200S set a land speed record for jet production its kind in the Bonneville Salt Flats, exceeding 174 mph (280 km / h).

In the years following the implementation of K1200S, BMW has also launched the roadster K1200R naked and K1200GT sports tourer, which started appearing in dealerships in spring (March-June) 2006. All three new K-Series motorcycles are based on the new inline four engine cylinders, with slightly different degrees of power. In 2007, BMW added the K1200R Sport, a semi-faired sports touring version of the K1200R.

In October 2008, BMW launched three new models of 1300 cc K series, the K1300R, K1300S and K1300GT. K 1300 models feature increased engine capacity of 136 cc, 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 cylinders "Boxer" engines have also been renovated. The new fighter displacement is less than 1,200 cc, and is affectionately referred to a "hexhead" because the shape of the cylinder. This engine is more powerful, and all bikes that use it are lighter.

The first motorcycle to be launched with this update motorcycle engine was R1200GS dual-purpose. The R1200RT tourer and R1200ST Sport Tourer followed shortly behind. BMW then introduced the 175 kg (390 pounds), 105 kW (141 hp) HP2 Enduro, and 223 kg (490 lb), 100 hp (75 kW) R1200GS Adventure, each is specifically aimed at off-road and adventure tourism segment Motorcycle, respectively. In 2007, the HP2 Enduro joined the road-biased HP2 Megamoto equipped with alloy wheels and smaller tires the street.

In 2006, BMW launched the R1200S, which has an output of 90 kW (121 hp) @ 8250 rpm.

F 800S

F Series

BMW also attention has been paid to the Series F in 2006. It cut the price in the current F650 and F650GS Dakar &GS; and F650CS removed to make room in the lineup for the F800 series totally new. The new motorcycles are powered by a double parallel engine built by Rotax. They have a belt drive system, similar to the drive belt found on the F650CS now deceased, or chain drive. Initially, BMW launched two new models of the F800 series, the sport bike F800S and F800ST sport tourer, the were followed for F650GS and F800GS motorcycles dual purpose, since both use the 798 cc engine despite the different names.

G650 Xchallenge enduro

G Series

In October 2006, BMW announced the G Series all-terrain style co-developed with Aprilia motorcycles. These are equipped with an improved 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 with automatic transmission per chain. There are three models in the series, all produced by BMW by Aprilia at its plant in northern Italy Scorza, each focused on a slightly different market:

G650 Xchallenge hard enduro with 21-inch front and 18 inch rear spoked wheels

G650 Xcountry encoder / adventure sports with 19-inch front and 17 inch rims Rear 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 way, "HP2 Megamoto equipped with alloy wheels and smaller tires on the street in 2007.

In April 2007, BMW announced its return to road racing competitive team entering a factory with a "Sport Boxer R1200S version four endurance races of 24 hours .. In 2008 they released this as the HP2 Sport.

S1000RR

Main article: BMW S1000RR

The bike is a super S1000RR launched to compete in the 2009 Superbike World Championship. It is powered by a 999 cc (61 cubic inches), inline-four engine producing 193 hp (144 kW).

Husqvarna acquisition

In July 2007, was BMW announced it has signed a contract for the acquisition of Husqvarna Motorcycles, including its production facilities and personnel from the Italian manufacturer MV Agusta.

Engine types

There are four lines of BMW motorcycles,

F & G series single

Twins F Series

R Series

K series

The series differ mainly in the kind of engine that each uses.

F and G series single

Series F, Single cylinder BMW motorcycle was first launched in 1994 as the F650, and was built by Aprilia around a carburetor four-stroke 650 cc, four-valve engine single piston, and the chain of transmission. The mission of the F 650 was to provide an entry level BMW motorcycle. In 2000, the F650 was redesigned, now with injection fuel, and called the F650GS. A terrain model focused F650 Dakar was launched the same year. 2002 saw the addition of motorcycles' Scarver "the F650CS the top line. The Scarver was different variants F650GS, because it uses a belt drive system opposed to a chain, had a height much low seat and was designed for road use. All 650 motorcycles produced from 2000 to 2007 uses a 652 cc engine built in Austria by Rotax and were built BMW in Berlin.

In late 2006, the G Series of motorcycles off-road biased bike was launched with the same 652 cc engine mounted on the F650GS, but the motor is no longer manufactured by Rotax.

In November 2007, the sport G450X enduro motorcycle launched a 450 cc single cylinder engine. The G450X contained several technological improvements in the Japanese motorcycle racing field, but the most unique and significant was the use of a single pivot point for the sprocket and the swingarm. This unusual configuration allowed for a very tense drive chain without decanting and acceleration squat deleted. The benefit of ex saves wear chain and sprocket and later allows a drive geometry more consistent and fully available rear suspension travel during heavy acceleration.

Twins F Series

In mid-2006, F-Series has added two new motorcycles to the lineup, the bike sports tourer 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 F650S. In 2007, the F650GS single cylinder was replaced by two cylinders F800GS and F650GS models. The latter uses a refined version of 798 cc engine mounted in F800GS, marking a point of departure for BMW naming convention.

R Series

Four different valve covers BMW.

two fins valve cover R68, 1954

Series I is built around a horizontally opposed boxer engine horizontally opposed. As the engine is mounted a longitudinal crankshaft, cylinder heads and protruding beyond the sides of the frame, so the R-series motorcycles distinctive visual. Originally R series bikes were air-cooled heads ("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 "airhead" to cover in a 1973 R75 / 5 is top left. The first "oilhead" cover, introduced in model year 1993 in Europe and 1994 in the U.S. is the top right. The "oilhead" covered in a R1150RT, with two spark plugs per cylinder, lower left. The last "hexhead" cover with a protective cover optional valve in a R1200RT, is down to the right.

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, laid on its left side with the butt of the left and crank right. It's called the "Flying Brick" because of the appearance of this provision. Sales did not meet the expectations of BMW, and production ceased with the 1993 model. At the end of K-series career, had 6,921 units produced. In 2004, BMW introduced a water-cooled 4-cylinder transverse to 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 production motorcycle in the K series was the K100, which was introduced in 1983. It was followed by the K100RS in 1983 K100RT in 1984, and K100LT in 1986. In 1987, the K100 (Mark II) was introduced with ABS brakes, the first on a motorcycle. In 1988 and until 1993 was the BMW K1, going a full version the K 100 with the new rear suspension Paralever style. I had the Bosch Motronic fuel injection system. At first it cost 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. It was followed by K75S, the K75, and the version K75RT Touring. The last year of production of motorcycles was 1996 K75.

In 1991, BMW increased the displacement of the K 100 to 987 cc, and the model designation became the K1100 (1097 cc). The K1100LT was first with the new engine. In 1992, the K1100RS is introduced, ending the year 8 production K100 models. In 1998 BMW increased the size again to 1170 cc. This four-engine planes appeared on the K1200RS updated. In 2003, the fully faired K1200GT, equipped with hard side cases and a larger screen with electric height adjustment. K1200RS chassis was expanded and strengthened to luxury touring BMW K1200LT model, which is still production in 2009.

K1200 engine is a 1157 cc later in transverse line four, announced in 2003 and for the first time in 2005 K1200S. The new engine produces a healthy 123 kW (165 hp), 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 cross-K1200 K1200S, R, R and GT Sport.

In October 2008, BMW announced the new K1300GT, K1300R K1300S models and, all of which have greater production capacity of 1,293 cc to 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.

Model designation

BMW motorcycles are named according to a three-part code consisting of the engine type, the approximate volume of the engine, and the style information (eg sports, sports tourism, luxury tourism, etc..) The three parts are separated by spaces.

Before the introduction of the K100 series and R1100 series motorcycles, the prefix letter was always the same, and the numbers were based on displacement, as mentioned above, or were just model numbers.

Technology

BMW is a worldwide leader in innovative technologies successfully suspension of the motorcycle.

rear suspension on one side

The first suspension BMW Monolever appeared in 1980 in the then new R80G / S rank Had a single board universal immediately behind the engine / gearbox unit. This system was later included in updated versions of the series K & R.

Paralever

Paralever is another step forward on one side of BMW rear suspension technology (pictured right). Is decoupled torque reaction as the suspension is compressed and spreads, avoiding the tendency to squat under braking and reducing the talk of the tires on the road surface. It was introduced in 1988 R80GS and R100GS motorcycles.

BMW revised Paralever invested in a R1200GS adventure.

In 2005 with the introduction of the "hexhead, BMW invested Paralever and moved the arm twisting of the bottom of the upper drive shaft housing (photo right). This reduces component underhang and tends to increase ground clearance on the right lean.

It is believed [by whom?] That the term Paralever developed because of the appearance of a parallelogram between the four elements that make up the rear suspension (rear-drive shaft, transmission, and lower or higher boost). Other motorcycle manufacturers have proprietary versions of this system, including Arturo Magni MV Agusta and Moto Guzzi compact reactive shaft.

Telescopic front fork

In 1935, BMW became the first manufacturer to form a hydraulically damped telescopic fork with their motorcycles. [Citation needed] Nimbus of Denmark had been appropriate telescopic forks since 1934, but his version was muffled until 1939. [Citation needed] BMW telescopic fork still used today in its Series F, Series HP G and motorcycles. The series R and K-series and use the front suspensions Telelever Duolever.

Earles front fork

Ernest Earles designed English triangular single fork that resists side forces introduced by sidecar (as opposed to the telescopic forks.) BMW equipped the Earles fork for all models for 14 years from 1955. In the event, this was the year that the use of sidecars peaked and quickly fell in most European markets (Eg the UK) but the Earles fork system was loved by pilots in solo as well. This causes the front end of the bike to stand up under braking to reverse the action of a telescopic fork. The mechanical strength of this design is sometimes a weakness for the rest of the bike, since transfers impact pressure to the structure where the damage is more difficult and costly to correct.

Telelever front fork

BMW Front Suspension Telelever a R1150R.

The system was developed by Saxon Telelever-Motodd in Britain in the 1980's. The Telelever is a front fork, where the shock absorber is located between and behind the two primary tubes attached to an arm Telelever.

This reduces unsprung weight as well as uncoupled placement function wheel fork of the shock absorption function - eliminating brake dive and superior traction in situations hard braking. This system improves comfort and stability while providing considerably excellent handling and sporty.

In the photo at left shows the Telelever suspension unit. The two fork tubes do not provide cushioning or suspension. The front of the light gray "An arm" can be seen arriving from the engine side of the (hidden) cross brace between the fork tubes.

Duolever

The top of the suspension Duolever

In 2004, BMW announced the K1200S, which incorporates a new front suspension based on a design by Norman Hossack. BMW recognized this fact, but paid no copyright Hossack. BMW named to its new front suspension Duolever. Since 2009, the K1300S is Duolever, K1300R and K1300GT.

The official BMW Motorrad Duolever explanation is:

The front wheel suspension is kinematically Duolever considered a square joint, in which two bonds forged behind allocated through Mobile bearings to the structure. These links are dragging, which visually resemble a fork conventional phone company too rigid wheel torque cast aluminum molds permanently. A central strut, which adjusts the suspension damping is linked to the lower of the two flight links, and leans against frame.

A trapezoid joint mission control mounted on the head and the wheel carrier is coupled with the handlebars. This conveys the cut set of movements direction. Therefore, the design Duolever in contrast to the telefork not need fixed and sliding tubes. At the same time, separates the steering and damping Telelever more consistent than shown.

The advantage of this suspension of the front wheel of the motorcycle market today is its torsional rigidity. The BMW Motorrad Duolever front wheel suspension is not influenced by negative forces in the same way as conventional telefork off as fixed and rotating tube side and and longitudinally during swing / bounce and direction. His two links back to absorb the forces resulting from swing / bounce and maintain stable wheel holder. Therefore, excluding any twisted and front wheel suspension is very precise. The driver's steering commands are converted directly and the comments of the wheel front is transparent in all driving conditions.

A cinematic effect anti-dive is also achieved, as for the Telelever, due to the disposition of the end link bearings. While a conventional strong telefork during braking maneuvers jounces largely or crashes, Duolever suspension travel still has enough left in this situation, so the pilot can still brake very late corner but directionally stable.

The obstacle avoidance maneuver the front wheel when driving on uneven surfaces can be converted to similar Duolever the behavior of a telefork. In connection with low unsprung weight and small separatist forces of the system, this translates into characteristics of the most sensitive and comfortable response.

Restoration

Fans of vintage BMW motorcycles are growing rapidly in number. As time marches, which BMW enthusiasts consider "Vintage" is amended. BMW pre-war are the most coveted, as demonstrated during the Gooding Auction & Company in California in October 2006 when a 1925 BMW R32 sold for $ 77,000. [Citation] Need

A contest R50 / 2 is the stage at MidAmerica Auctions in Las Vegas in 2007

Piston-frame models from the 1950 are the next most coveted, and then "Slash-2" variants from 1955 to 1969. In recent years, the "Slash-5" of the 1970 model a 1973 years model have begun to join that exclusive club. Historical prices of BMW models have been increasing rapidly, fueled in part by the motorcycle auctions as the great auction half of the United States is held every January in Las Vegas, Nevada.

Reviews for the treatment of vintage motorcycle varies their condition and tastes of their owners. The first preference tends to be for the preservation of the original machine if you are in reasonably good condition. second preference is limited to restoring, maintaining as much original fabric as possible. Third, when a machine is in poor condition, is called frame Monitoring of the restoration. In the latter case, the bike is completely disassembled and each individual part is refurbished and then the bike is reassembled as sharp possible to the original design, but modern times with replacement parts, such as stainless steel or plated parts that were not originally 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 minor detail. Unlike many other brands of motorcycles, parts for old BMW, while expensive, can be obtained from sources in Germany and the United States.

There are several BMW motorcycle Professional restorers at work in North America and Europe. Two members of American organizations, Vintage BMW Motorcycle Owners and the BMW Motorcycle Club Veterans of the United States is dedicated to the preservation of vintage BMW motorcycles.
