TheBMW GS is a model series ofadventure-touringmotorcycles produced byBMW Motorrad since 1980 until present day. TheGS acronym has had several different meanings over the years. Originally designerHans Muth had intended to call it the "Gentleman's scrambler" but it was later launched under the nameG/S meaning "Gelände/Straße" (Lit.: terrain/street).[1] Later models removed theforward slash and nowGS is generally accepted to be german for "Geländesport" (Lit.: terrainsport).[2]
The GS models of motorcycles can be distinguished from otherBMW models by their longer travelsuspension, an upright riding position, and larger frontwheels – typically 19 or 21 inch.
The BMW GS is generally accepted to be the first "adventure bike" combining some off-road capability of adual-sport motorcycle, with the comfort and luggage carrying ability of a touring motorcycle.[3][4]
The BMW GS is also a commercial and historically significant model for BMW Motorrad. Before its launch in 1980 the motorcycle division of BMW was struggling financially and in early 1979 the new director of BMW MotorradKarl-Heinz Gerlinger was tasked with either making the motorcycle business profitable or shutting it down entirely.[5] Initially some reviewers of the new R80G/S model were unimpressed with the compromised dual nature of the motorcycle, with the magazineMotorcyclist calling it "barely capable of holding its own [and] heavy and akward".[6] On the contrary the German publicationMotorrad claimed the R80G/S was "the best roadbike BMW has made yet".[3] By the end of 1981 BMW had sold 6,631 R80G/Ss which was more than twice the number originally hoped for, contributing to saving the motorcycle division.[1][7]
The GS models have gone on to become the best selling model in BMW Motorrads lineup. On 21 June 2023 BMW announced they had produced their one millionthboxer-engined GS motorcycle.[8]
The GS has been produced in several distinct models and generations of differing engine configurations. By enthusiast these are typically distinguished and nicknamed based on the engine powering them.

The first BMW GS model was theR80G/S powered by a 797.5 cm³air-cooled, 2 cylinder boxer engine.[9] It was powered by theBMW 247 engine which was also fitted to many other bikes in the BMW range of the time. This engine is known as the "airhead" because it relies on airflow across both the cylinders andcylinder heads to provide the majority of its cooling. These early models used a combined rear suspension,drive shaft andswingarm called a "Monolever".
The most collectible model of this generation is probably the R80G/S "Paris-Dakar" model featuring a larger fuel tank, a single seat and a luggage rack. This model was launched in celebration of the R80G/S wins in theParis Dakar Rally.[10][11][12]
In certain markets a smaller 649.6 cm³ R65GS version was also available. With a lower power output of 20 kW (27 hp), this was targeted at riders with restricted licenses and was also sold to some nations' military forces.[13][14]
In 1987 the G/S name was changed to GS (see above) and the Monolever was replaced with the "Paralever" swingarm. This system included atorque arm intended to lessenshaft effect and strengthen the swingarm tofinal-drive connection. A host of other updates included a bigger subframe, a newfront fork andtubeless rims. The new bikes were produced with engines of 797.5 cm³ (R80GS) and 980 cm³ (R100GS).[2][15]
Production of the standard machines stopped in 1995 with the R100GS Paris-Dakar, but special "Kalahari" and "Basic" editions were produced until December 1996, which ended airhead GS production.[16]
Airhead models still have a strong following among adventuremotorcyclists, due in part to the design of the machines being easy to work on making them simple to service and repair, and their solid and reliable design makes them suitable for traveling.
Airhead GS models are listed below together with production figures where known:
| Model | Years | Production count |
|---|---|---|
| R80G/S | 1980–1986 | 21,864[17] |
| R80G/S Paris Dakar | 1984–1987 | |

In 1994 the next generation (Type 259[22]) of BMW GS was introduced with theR1100GS.[23] This generation is commonly referred to as the "oilhead" due to the engine relying more onoil-cooling than the previous version. In 1998 it was followed by a smallerR850GS model, which was largely identical besides a less powerful engine.[24]
The R1100GS model signified a significant jump in technology introducing features like afour-valve engine,electronic fuel injection, acatalytic converter andABS-brakes. BMW also claims it was the adventure motorcycle with the "biggest capacity and greatest power output" of the time.[23]
The R1100GS also introduced the "telelever" front suspension to the GS range, a feature still employed in current models. This replaces the conventional forks with an A-shapedcontrol arm and ashock absorber. This system is intended to improve performance of the front suspension by separating the forces exterted by weight shift of the chassis, from the forces generated by bumps from the road surface. It also eliminates compression of the front suspension under braking, called "brake dive".[25]
In 1999 the model was updated to the R1150GS (Type R21[26]). This model received a slight increase in engine power and displacement, a change in design of the front fairing and headlight - now sporting two round asymmetrical headlight lenses. The R1150GS also received a 6-speedgearbox, up from the previous 5-speed. In September 2001 the "Adventure" model was announced which is analogous to the earlier Paris-Dakar models.[27] This model added a larger fuel tank, lower gearing, longer suspension travel and optional off-road tyres. This was done to make the Adventure more suitable for arduous off-road trips with a heavy load of gear and supplies. The R1150GS models is by many regarded as the motorcycle, that kickstarted interest in traveling on big adventure bikes.[27]
Oilhead GS models are listed below together with production figures where known:
Model Years Production count R1100GS 1994–1999 39,842[28] R850GS 1996–2001 2,242[29] R1150GS 1999–2004 58,023[30] R1150GS Adventure 2001–2005 17,828[30]
In 2004 theR1200GS model introduced the third generation (Type K25[31]) of GS models. Commonly referred to as the "hexhead" simply due to the hexagonal shape of the cylinder heads.
While not representing as big a change in basic design, as there had been between the first and second generation, this model took many of the ideas of the previous version and improved upon them. Most notably the R1200GS was significantly lighter, shedding some 30kg from itswet weight compared to its predecessor.[32] Interestingly 13kg of this reduction came solely from weight savings in the gearbox.[33] The engine of R1200GS model gained a significant amount of power while at the same time being both smoother and more economical, due to gaining abalance shaft and improved fuel injection.[33]
In 2008 the R1200GS received an update, that made thesteering geometry steeper and added 5hp. The biggest innovation was probably the implementation of Electronic Suspension AdjustmentESA, which enabled the rider to change the characteristics of bothdamping andpreload of the shock absorbers via the switchgear.[34]
In 2010 another update was made to the model, this time with the engine receiving the biggest changes. Thevalvetrain was changed from employingpushrods androcker arms to a doubleoverhead camshaft design. This allowed for a higherrevlimit and an additional increase of 5hp, now up to 110hp in total.[35] This design was originally made for theBMW HP2 Sport and later employed in several other models.[36] Although still hexagonal in shape, this represented a pretty big technical change to the cylinder heads. For this reason some enthusiasts refer to these later engines as the "camhead" to differentiate it from the earlier engine types.[37]
The R1200GS would prove to be big a commercial success for BMW Motorrad. On 27 July 2007 the R1200GS became the first model to be produced in 100,000 units.[38]
Hexhead GS models are listed below together with production figures where known:
| Model | Years | Production count |
|---|---|---|
| R1200GS | 2004–2012 | 84,373 up to 27 July 2007 |
| R1200GS Adventure | 2006–2013 | 15,627 up to 27 July 2007 |
In 2013 the newR1200GS model introduced the fourth generation (Types K50[39] and K51[40]) of GS models. Although the model name and engine capacity remained the same, the fourth generation represented a big change in engine layout and design language.
For the first time a BMW boxer engine was of"unit construction", where engine and gearbox was combined into a single unit. Other innovations was the usage ofliquid cooling of the cylinder heads,Ride-By-Wirethrottles and awet clutch. While none of these technologies were groundbreaking they were all firsts for a BMW boxer engine.[41]
The R1200GS also introduced "ride modes" to the GS models. This idea (pioneered byDucati's Multistrada) allowed riders to select different modes that changes the response of the engine and suspension, significantly altering the riding experience. The suspension was updated toDynamic ESA which not only allowed electronic adjustment like previously, but also allowed the suspension system to autonomously and continuously adjust the suspension's settings to best suit the current conditions.[42] Another notable change was the swapping of positions of the Paralever drive shaft and the exhaust from right-to-left. This was done to prevent riders burning themselves on the hot exhaust pipe.[42]
In 2017 the R1200GS received an update that slightly changed the design of the fairings, the workings of the Dynamic ESA suspension and the engine calibration was updated to comply with theEURO4 emissions standards.[43] Although BMW claimed the same 125hp as previous years German magazine Motorrad tested this and found the updated engine very slightly weaker.
In 2019 BMW introduced the R1250GS models. Just like the 2010 update to the previous model, the most significant change was updates to the engine which grew from 1170cm³ to 1254cm³ and the valvetrain was redesigned to incorporate BMWs system forvariable valve timing called "ShiftCam". This system allowed for an increase in output of both power and torque at the same time, to 136hp and 145nm respectively. This made it the most powerful production boxer engine BMW had made at the time.[44][45] Other notable changes included a colour TFTinstrumentation and anLED Headlight now being standard equipment.[44]
Wethead GS models are listed below:
| Model | Years |
|---|---|
| R1200GS | 2013–2018 |
| R1200GS Adventure | 2014–2019 |
| R1250GS | 2019–2022 |
| R1250GS Adventure | 2020–2023 |
On 28 September 2023 the fifth generation of BMW GS was announced, the R1300GS. (Type KA1[46])[47] The engine was again a completely new design. Like the predecessor the engine is a unit construction but internal components were rearranged, with the gearbox now located below the cylinders and crankshaft, allowing for a shorter and more compact engine. The construction of the chassis was a big departure from previous models, all of which were constructed of tubular steel. The chassis of the R1300GS is made of pressed sheet steel, with the subframe beingdie-castaluminium. Recognising that weight had continually crept up over the last few generations, project managerReiner Fings claimed that "at the top of the list is to lose weight." All of these changes were made in an attempt to make the new generation lighter and more compact. Another notable change was the new design of the front headlight which was no longer asymmetrical - a feature that had been present since the R1150GS.[48]
A little under a year later on 5 July 2024, the sister model BMW R1300GS Adventure (Type KA2[49]) was announced during BMW's "Motorrad Days" event inGarmisch-Partenkirchen.[50] Just like the preceding Adventure models the R1300GS Adventure has a bigger fuel tank and an increased focus on comfort while traveling. The system Automated Shift AssistantASA was introduced on this model, electronically automating the control of the clutch and gearshifting, effectively giving the motorcycle anautomated manual transmission. The design language of the "standard" and Adventure models is also noticeably more differentiated between the two models, than earlier generations.[51]
Another notable development on both 1300 models is "Dynamic Suspension Adjustment". This system allows to control both the suspensionride height and stiffness ofspring rate via hydraulic circuits, in addition to adjusting the damping and spring preload like previous versions.[50]

In 1993 BMW introduced the off-road-capableF650 Funduro. This bike was powered by a single cylinder 4-valve 652 ccRotax engine, had a 19-inch front wheel, long travel suspension, abash plate, a high seat and a low weight of just 189kg.[52][53] It was also the first BMW motorcycle ever to featurechain drive.[54] This bike was developed in cooperation withAprilia and was virtually identical with the 5-valveAprilia Pegaso. While technically not bearing the GS moniker, the "Funduro" would later be further developed and renamed as the F650GS model in 2000.
BMW introduced the fuel injected F650GS following BMW's wins in the 1999 and 2000 Dakar Rally with a heavily modified F650RR ridden byRichard Sainct.[10] A taller, more off-road biased F650GS Dakar version was also introduced which included a taller windscreen, 21 inch front wheel and longer suspension travel.[55][56]
BMW re-branded the single-cylinder bike as theG650GS in some markets due to the launch of the parallel twin-cylinder model in 2008, confusingly also named the F650GS (see below). In 2010 at theEICMA show in Italy BMW Motorrad announced the global availability of the G650GS with a slightly down-rated engine producing 35 kW (47 hp).[57] A year later the BMW G650GS Sertão was announced. Effectively the successor to the Dakar model, it featured taller suspension and a 21 inch front wheel.[58]
In 2017 BMW unveiled the entry level G310GS with a 4-valve, dual overhead cam, liquid-cooled 313cc engine.[59] The G310 models were the first products of BMWs cooporation withTVS Motor Company, and as such were the first GS models to be built in India.
The single-cylinder bikes have a strong following and are thought by many of their riders to be better off-roaders than the heavier boxer-engined bikes. Like the larger two-cylinder models, they offer significant capacity to carry gear and supplies over long distances. Their versatility is attractive to riders who intend to spend a long time traveling on two wheels.
Single-cylinder GS models are listed below:
| Model | Years |
|---|---|
| F650GS | 2000–2007 |
| F650GS Dakar | 2000–2007 |
| G650GS | 2008–2017 |
| G650GS Sertão | 2011–2017 |
| G310GS | 2017–2025 |
In 2007 BMW launched two new GS models called theF800GS and F650GS. They both use the Rotax-built 798 cm³parallel-twin engine introduced a couple of years prior with the BMW F800S and F800ST.[60] This engine produces a power output of 63 kW (84 hp) and torque of 80 N⋅m (59 lb⋅ft).
Although it is made with the same capacity engine as the F800GS, the F650GS produces a lower power output of 52 kW (70 hp) and torque of 75 N⋅m (55 lb⋅ft). This model therefore began the practice of the model name not necessarily coinciding with the actual engine capacity.[61] This detuned engine could be further restricted to 25 kW (34 hp), which made it possible to meet then-current regulations for European restricted licenses.[62]
In 2013 the F800GS was refreshed and the F700GS replaced the F650GS. These new models introduced a host of updates including updated design of the fairings and instruments, new switchgear and the possibility of adding Electronic Suspension AdjustmentESA on the rear axle as an optional extra.[63]

On 7 November 2017 BMW announced the F850GS and F750GS models.[64] Featuring a brand new design of both chassis and engine these models replaced the F800GS and F700GS. The new models changed the chassis from tubular steel to a steelmonocoque design (much like the R1300GS would later do in the boxer-range). The new engine was a brand new design with a new crankshaft offset of 270°, producing a differentfiring order. The engine was produced in China by BMWs partnerLoncin which at the time sparked some controversy.[65]
In September 2023 BMW announced that the F850GS and F750GS were being replaced by the updated F900GS and F800GS - with the F800GS name being reused for the new model. Much like its R1300GS sibling, the new F900GS model was focused on making it slimmer and lighter than its predecessor, while improving the performance of its engine and suspension especially off-road.[66]
At the EICMA trade show in 2025 BMW unveiled the production version of the F450GS. This new model is powered by a 450cm³ parallel-twin engine with a unique 135° crankshaft offset. This engine produces 35 kW (47 hp) making it A2-licence compliant. Production of this model is set to commence in 2026 by TVS in India like its predecessor, and it will replace the G310GS in the lineup.[67][68]

In 2002Kevin and Julia Sanders rode around the world on a BMW R1150GS. They managed to set a recognisedGuinness World Record for circumnavigating the earth in a time of 19 days, 8 hours and 25 minutes.
In 2004 theR1150GS Adventure became a top seller after being used by actorsEwan McGregor andCharley Boorman in their journeyLong Way Round. It was a major sales coup for BMW as the duo had initially approachedKTM for sponsorship for the trip, who turned them down.[69] Their journey involved riding from London to New York by going east across Europe, central Asia, Alaska, Canada and the USA. The duo continued their association with the BMW GS when Boorman used anF650RR during his attempt to finish the 2006 Dakar Rally. This journey was documented in the book and TV seriesRace to Dakar.[69] Again in 2007 McGregor and Boorman used theR1200GS Adventure in their journeyLong Way Down, in which they rode fromJohn o' Groats at the northern tip of Scotland, toCape Agulhas in South Africa at the southern tip of the African continent.
Both the R1200GS and the F650GS were featured in the BBC TV seriesThe Hairy Bikers' Cookbook ridden by chefsDave Myers andSi King.[70][71]
Drummer andlyricistNeil Peart of Canadian bandRush used anR1100GS for a 14-month, 55,000 miles (89,000 km) self-healing trip, documented in the bookGhost Rider: Travels on the Healing Road[72]. He made the trip in the late 1990s following the deaths of his only daughter and his wife.[73] Peart also used the R1200GS with an R1150GS as a backup on his 2004 motorcycle trip between gigs on Rush's 30th Anniversary tour, a trip he documented in the bookRoadshow: Landscape with Drums, A Concert Tour By Motorcycle.[74]
Television food personalityAlton Brown and his crew rode R1200GS motorcycles during season 2 of the television programFeasting on Asphalt. They rodeBMW R1200RT motorcycles during season 1 but found the GS better suited for thebackroads they often found themselves on.[75]
