Maintenance Tips:
Regular chain maintenance is crucial for drivetrain longevity. Keep battery terminals clean and charged to prevent starting issues. Monitor fork seals for leaks.
Bmw Motorrad:
BMW Motorrad has a long-standing reputation for building reliable, innovative, and capable motorcycles, particularly known for its boxer-twin touring bikes and later its single-cylinder F series.
F650 Lineage:
The F650GS lineage began with the F650 Funduro (single-cylinder, Rotax-built engine) and evolved into the fuel-injected F650GS, offering improved performance and refinement. This manual likely covers variants derived from the Rotax 652cc engine platform.
Production Period:
The F650GS model range, based on the single-cylinder Rotax engine, was produced roughly from the late 1990s through the mid-2000s before being succeeded by the F700GS and F800GS.
Manufacturing Location:
Typically manufactured in Germany and/or Austria (engine by Rotax in Austria, assembly in Germany).
