The BMW F650 is a family of motorcycles that was produced by BMW Motorrad beginning in 1993.[1] Models include the F650ST Strada, F650 Funduro, F650CS Scarver, F650GS, and F650GS Dakar. The 1993 F650 Funduro and Strada were the first single-cylinder motorcycles from BMW since the 1960–1966 R27, and the first chain driven motorcycles from BMW.[1]

1993–2000: F650 Funduro and Strada
The BMW F650 Funduro and F650ST Strada were introduced to Europe in 1993 and to the United States in 1997.[2] The bikes were jointly designed by BMW and Aprilia, who launched their model as the Pegaso.[3] The BMW bikes, which were built in Italy by Aprilia, were powered by an Austrian 652 cc single-cylinder Rotax engine.[2] It was the first BMW motorcycle with chain drive.[2][3] There were two variants: the F650 Funduro was a dual purpose bike, and the F650ST Strada had a smaller 18 inch front wheel and was intended for street use. Both models used two 33 mm Mikuni carburetors.[3]
In 2000,[1] BMW introduced the F650GS to replace the Funduro, and the F650CS Scarver to replace the Strada. In 2001, the original F650 was discontinued.
2000–2007: F650GS, F650GS Dakar, and G650X
Produced from 2000 to 2007, the BMW F650GS is a dual-purpose motorcycle. It sold over 105,000 units during its production life.[1][4] It was available in a lowered model with lower seat height from a shorter rear shock, a standard model, and a taller more off-road oriented "Dakar" model. The Dakar model had a thinner, 21 inch front wheel (as opposed to the standard 19 inch) and longer suspension travel for improved off-road handling. It also had a thicker, higher seat. It was named after the Paris Dakar Rally, which BMW rider Richard Sainct won on the F650RR in 1999 and 2000.
Its specifications put it in the 650 cc dual-sport class, competing against bikes such as the Kawasaki KLR650, Suzuki DR650, Honda XR650L, KTM LC4 640, Yamaha XT660 and Honda Transalp.
A specially prepared rally raid version of the bike was used by Charley Boorman and his team during the 2006 Dakar Rally while filming their documentary Race to Dakar.
The G650X series was released as 2007-year models, consisting of the off-road X-Challenge, the scrambler-style X-Country, and the road-oriented X-Moto. This series was discontinued after the 2009 model year.
Design and technology
The F650GS had several advanced technology features for its time, with computer-controlled fuel injection,[when?] catalytic converter, a Nikasil-lined cylinder, optional ABS and an airbox designed to exploit the airflow pattern of the bike when in motion. Combined with the bike's high compression ratio and twin spark plugs (from 2004 onwards), excellent fuel economy and low emissions existed alongside high power output. The original F650 single-engine was manufactured for BMW by Austrian company Rotax while the bike was assembled by Aprilia. When the F650GS was launched,[when?] the full process was brought back in-house.
In 2000 the German motorcycle magazine Motorrad reported about a defeat device delivered within the BMW F 650 GS. BMW responded in issuing an improved injection as of 2001 and calling back the models from the previous year.[5][6]
Amongst the changes from the earlier F650 Funduro, the engine was upgraded to a 43 mm throttle body. The fuel is stored in an under seat fuel tank,[7] and the false tank (where a conventional fuel tank would be) housed the remote oil reservoir (for the dry sump), airbox and battery. This contributed to a lower centre of gravity for improved handling.[1] The bodywork was redesigned by head BMW designer David Robb.[1]
Due to the high numbers sold, the F650GS developed a large aftermarket accessories range and a sizeable owner community. BMW also developed a large range of factory original hard luggage for the bike.
2008: F650GS parallel-twin

In 2008, the single-cylinder F650GS was discontinued and replaced by an all-new design featuring a 798 cc, parallel twin engine. Intended as a new-generation replacement for the old bikes, the new motorcycle has retained the same F650GS model name, despite the fact that it has a larger engine.
2009: G650GS
<templatestyles src="Module:Hatnote/styles.css"></templatestyles>
In late 2008, BMW relaunched the original single-cylinder F650GS under the new name G650GS in the United States, South America, Greece[1] and Australia.[4][8] The new G650GS is essentially the 2007 single-cylinder F650GS brought back into production with some minor modifications and with the engine assembled by Loncin in China instead of Rotax in Austria, but still using parts manufactured by Rotax in Europe.[1][9][10] The finished engines are shipped back to BMW in Germany where the bikes are assembled. G650GS models with the Chinese-assembled engines can be easily identified as the engines are painted black while in the earlier European-assembled engines were finished in silver. For a short period prior to discontinuation of the bike in 2007 the engines were assembled by Kymco in Taiwan.
The G650GS received some upgrades over the F650GS of 2007: the engine now produces 3 additional horsepower (now 53 hp) and received a stronger 400 watt alternator.[1] In the United States and Australia, ABS and heated grips are now standard equipment instead of additional cost options.[1] An emergency services specific version of the G650GS, fitted with blue lights and sirens, is available from BMW Motorrad's Official and special duty vehicles division.[11]
In 2010, at the EICMA show in Italy, BMW Motorrad announced the global availability of the G650GS with a slightly down-rated engine producing 35 kW (47 hp).[12][13]
In 2012, BMW released the G650GS Sertão, which is a more off-road capable version. The Sertão fills the product gap that was left when the F650GS Dakar was discontinued in 2008.
