Bought an R1200RT new in 2005, since done 31k miles. ESA failed after 4 days, took BMW more than 2 years to make it work properly.Throttle jammed due to incorrect assembly. Horn bracket fractured. Starter motor failed. RHS indicator switch failed. OIl leaks. Front engine cover and rear wheel replaced due to corrosion problems. Fuel pump elelectronics failed. Wiring harness to ignition switch fractured. Needle roller on final drive failed. Blew 8 headlamp bulbs. BMW washed their hands of it after 2 years.
Conclusion, lovely bike with totally unacceptable quality, good luck to prospective buyers, goodbye to BMW.....
