Bmw Motorrad Legacy:
BMW Motorrad has a long history of producing robust, reliable, and adventure-capable motorcycles, particularly renowned for its GS series (R80G/S, R100GS, R1100GS, R1200GS).
F650 Series Origin:
The F650 series, originating with the single-cylinder 'Funduro' (F650), was BMW's entry into the lighter, more accessible adventure-touring market. The F650GS refined this concept. Later F650GS models (post-2007) were often rebadged F800GS variants (e.g., F650GS Twin) with a lower-spec engine or chassis configuration.
Engine Development:
Initial models featured a Rotax-designed single-cylinder engine. Later generations adopted a parallel-twin configuration, leveraging the platform developed with the F800 series.
Production Period:
1999 to approximately 2007 for the single-cylinder F650GS. Later parallel-twin models continued under the F650GS nameplate until around 2012 before being replaced by the F700GS.
Manufacturing Location:
Primarily produced in Germany and South Africa.
