At Hornig, we support you with expert advice, high-quality components, and complete maintenance kits — ensuring that your motorcycle remains reliable, safe, and retains its value.

 

Recommended Maintenance Intervals – Overview

Even cruisers with boxer engines and shaft drive such as the R850C and R1200C benefit greatly from consistent maintenance. At Hornig, we provide practical guidance — please refer to your motorcycle’s owner’s manual for exact specifications.

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

 

Typical Service Tasks in the Maintenance Plan

  • Oil change & oil filter: Replace engine oil and oil filter regularly – at Hornig you will find matching branded components.
  • Check & adjust valve clearance: Especially important for the air/oil-cooled boxer engines of the BMW cruisers.
  • Check spark plugs and replace if necessary – for optimal engine performance.
  • Check or replace air and fuel filters – especially for short-distance use or dusty environments.
  • Check braking system: Pads, discs, lines, and brake fluid – matching brake pads and fluids available in the Hornig range.
  • Drivetrain & gearbox: Check oil level, inspect bearings, check shaft/final drive.
  • Electrical system & lighting: Check battery, inspect charging system, test lighting & signal functions.
  • Visual inspection: Check bolts, cables, throttle cables, wheels & tires for condition and safety.

  • Document all maintenance work – a complete service booklet increases your motorcycle’s resale value.
  • Use only spare parts and operating fluids approved for the boxer cruiser models – Hornig will be happy to advise you.
  • For frequent short trips, high loads, or heavy use, shorter maintenance intervals may be advisable.
  • For long storage periods or winter breaks: perform an oil change beforehand, disconnect the battery, and stabilize the fuel.
  • Safety-relevant work (e.g. brakes, driveshaft) should be carried out by a qualified specialist workshop if in doubt.
