On this page, you'll learn which maintenance intervals and service work are standard for the BMW R1250GS and R1250GS Adventure at customer service – clearly broken down into 10,000 km and 20,000 km intervals.

1. Inspection every 10,000 km (6,000 miles)

These regular maintenance checks (10,000 km, 30,000 km, 50,000 km, 70,000 km, etc.) include:

  • Diagnosis & vehicle test with BMW Motorrad diagnostic device
  • Engine oil change with filter (annually or every 10,000 km)
  • Air filter change (for off-road use, annually or every 10,000 km)
  • Shaft drive maintenance (oil change every 20,000 km or every 2 years)
  • Inspection of brake pads, discs, brake lines, and brake fluid
  • Check steering head bearings
  • Coolant level Check
  • Check tire pressure and tread depth, check spoke tension
  • Check side stand and center stand, lights, indicators, and signaling system
  • Test battery status and set service due date
  • Test engine shutdown function, final roadworthiness check

2. Major Service every 20,000km (12,000 miles)

At 20,000km, 40,000km, 60,000km, 80,000km, 100,000km, etc., these additional services are required:

  • Check and adjust valve clearance (every 20,000km)
  • Replace spark plugs every 20,000km
  • Change air filter element every 20,000km
  • Change cardan shaft oil (see above) and inspect the cardan shaft

3. Time-Based Maintenance

Regardless of mileage, a service should be performed at least annually – or at least every 10,000km. Brake fluid replacement is required after the first year, and then every two years – as per BMW standards.

4. Relevant Additional Information

BMW has introduced a lifetime free cardan shaft replacement warranty for newer models – free replacement at approximately 60,000 km (or earlier if wear is evident), regardless of ownership.

💡 Many maintenance tasks, such as oil changes, air filter changes, or valve clearance adjustments, can be performed by experienced motorcyclists themselves – however, certain functions, such as resetting the service interval, require special diagnostic tools such as the GS‑911 or Motoscan.

5. User Benefits and Maintenance Quality

  • Maximum reliability through regular maintenance according to the BMW service plan
  • Retention of vehicle value with a complete service history
  • Greater safety thanks to tested components and functioning electronics
  • Transparent cost control thanks to plannable maintenance steps
