Engine Type:
Rotax-built parallel-twin (for the F650GS Twin era) or single-cylinder Rotax engine (for earlier F650GS models). Specific engine details depend on the exact model year.
Horsepower Range:
Typically 35-50 HP depending on generation and specific model (e.g., F650GS vs. F650GS Dakar, F650GS Twin).
Torque Range:
Approximately 35-45 lb-ft (47-61 Nm) depending on generation.
Fuel Delivery:
Electronic Fuel Injection (EFI)
Engine Control Unit:
Siemens or similar ECU for fuel and ignition management.
Oil Change Interval:
Typically every 6,000-10,000 miles (10,000-16,000 km) or annually, refer to manual for exact spec.
Valve Adjustment Interval:
Around 12,000-18,000 miles (20,000-30,000 km), depending on engine type.
Chain Maintenance:
Regular cleaning, lubrication, and adjustment (check tension every 1,000-2,000 miles).
Engine Oil Type:
Synthetic or semi-synthetic motorcycle oil, API SG/SH/SJ or higher, JASO MA/MA2. Viscosity typically 10W-40 or 15W-50.
Coolant Type:
Ethylene glycol-based coolant mixed with distilled water (typically 50/50 ratio). BMW recommends specific coolants.
Brake Fluid Type:
DOT 4 or DOT 5.1 brake fluid (check manual for precise specification).
Fork Oil Type:
Specific fork oil weight (e.g., SAE 5W or 7.5W) and quantity, as per manual.
