This was later replaced by the F650GS Twin (2008-2012) featuring a parallel-twin engine (which shared DNA with the F800GS), effectively becoming the F700GS in later updates.
Key Single Cylinder Era:
Dominated by the Rotax-built 652cc engine, known for its robustness and torque delivery, making it a popular choice for riders of varying skill levels.
Key Parallel Twin Era:
Introduced a more modern parallel-twin engine, offering increased power and refinement, aligning with the F800 series platform.
Production Locations:
Primarily manufactured in Germany (Berlin-Spandau) and also in Italy (by Aprilia for some early models).
