Customer Service & Maintenance Intervals for Your BMW R850R, BMW R1100R, BMW R1150R & Rockster

 

With the right maintenance concept, you ensure the reliability and value retention of your classic BMW boxer models – specifically the BMW R850R, BMW R1100R, BMW R1150R, and BMW R1150R Rockster. At Hornig you will not only find a detailed overview of maintenance intervals and service tasks, but also high-quality spare and wear parts such as oil filters, brake pads, or seals for your motorcycle service.

 

Recommended Service Intervals – Overview

For your BMW R models, regular inspections are essential for performance, safety, and value retention. The typical intervals are:

  • Break-in / Initial Inspection: After approx. 1,000 km – first visual inspection, oil change with filter, valve clearance check if necessary.
  • Standard Inspection: Usually every 10,000 km or once a year – including oil change, filter replacement, visual and functional checks as well as valve clearance inspection.
  • Major Service: Every 20,000 km or every two years – including air filter, spark plug, and brake fluid changes, as well as drive/shaft inspection.
  • Brake & Operating Fluid Changes: Brake fluid at least every 1–2 years; check and replace gearbox and final drive oil depending on use and time interval.

 

Typical Maintenance Tasks During Service

  • Change engine oil & oil filter – using high-quality components available from Hornig.
  • Check valve clearance and adjust if necessary – an important task for air/oil-cooled boxer engines.
  • Check spark plugs and replace according to manufacturer specifications.
  • Check or replace air & fuel filters – especially with frequent short trips or dusty conditions.
  • Service the braking system: Check brake pads, brake discs, lines, and brake fluid for condition and function; matching brake pads available at Hornig.
  • Inspect drivetrain & gearbox: Check oil level, seals, and the shaft or final drive.
  • Check electrical system & lighting: Inspect battery, charging system, and all lighting and signaling components.
  • Visual inspection: Inspect bolts, cables, throttle cables, tires, and wheels.

Hornig offers a wide selection of service parts and maintenance kits specifically for your R models (R850R, R1100R, R1150R & Rockster). These include, among others:

  • Engine & gearbox oil in the correct specification
  • Oil filters, air and fuel filters, as well as sealing rings
  • Spark plugs & ignition system components
  • Brake pads, brake discs & brake fluid

  • Batteries, connector kits & electrical spare parts

With these kits, you can carry out maintenance tasks such as oil changes, filter replacements, or brake service efficiently and professionally – either in your own garage or together with your workshop.

 

Practical Maintenance Tips for Your BMW R Models

  • Document all maintenance work – a well-kept service booklet increases resale value.
  • Use only spare parts & operating fluids suitable for air/oil-cooled boxer engines – Hornig will be happy to advise you.
  • For intensive use (short trips, heavy load), more frequent service intervals may be useful.
  • Is your motorcycle stored for a longer period or over the winter? Then disconnect the battery, perform an oil change, and stabilize the fuel.
  • Safe maintenance: work on brakes, suspension, or electrical components should be carried out by a qualified workshop if in doubt.
