Maintenance Intervals / Maintenance Plan / Customer Service for Your BMW R1100RS & R1150RS

 

For your sporty touring boxer motorcycles BMW R1100RS and BMW R1150RS, here you will find all important information about maintenance intervals, typical service tasks, and suitable replacement & wear parts. At Hornig, you benefit from expert advice, high-quality service kits, and original components to keep your BMW reliable, powerful, and safe.

 

Recommended Maintenance Intervals – Overview

The R RS models with air/oil-cooled boxer engine and shaft drive are robust but require regular inspections to ensure performance, safety, and longevity:

  • Break-in / Initial Inspection: After approximately 1,000 km – oil change, oil filter, check valve clearance, as well as visual and functional inspection.
  • Standard Service: Usually every 10,000 km – including oil change, filters, valves, spark plugs, and electrical check.
  • Major Service: About every 20,000 km or according to the manufacturer's maintenance schedule – additionally check and replace air filter, brake fluid, gearbox and final drive oil.
  • Operating Fluids & Brake Fluid Change: Brake fluid at least every 1–2 years; check and replace gearbox and shaft drive oil as needed depending on usage (e.g., with Hornig shaft drive oil).
  • Belt Maintenance: At certain service intervals, the ribbed generator belt should be checked and replaced if necessary. The BMW maintenance manual explicitly recommends belt replacement every 40,000 km.

 

Typical Service Tasks During Customer Service

  • Change engine oil & oil filter – essential for reliable operation.
  • Check & adjust valve clearance – especially important for air/oil-cooled boxer engines.
  • Inspect / replace spark plugs – for smooth and stable ignition.
  • Air & fuel filter service – check or replace filters depending on usage.
  • Check brake system: Inspect brake pads, discs, lines, and brake fluid condition and function.
  • Drive & transmission: Inspect shaft drive, check oil levels, inspect seals.
  • Inspect / replace generator belt: The ribbed belt to the generator should be regularly checked for wear and replaced if necessary.
  • Electrical & lighting: Check battery, cable connections, lights, and signaling devices.
  • Visual inspection & fasteners: Check screws, cables, throttle cables, wheels & tires for tightness and wear.
