The only bike that has ever left me stranded on the roadside 800 miles from home was my Yamaha FJR when the immobilizer failed. There were no replacement parts available in the US and I waited 3 days before the dealer got authorization from Yamaha to replace my ignition switch with one from a FJR on the showroom floor. A few weeks later Yamaha issues a recall on the ignition switch because of faulty immobilizer antennas and I was able to get reimburse for the cost of parts/labor but not the 3 days food and lodging. My H-D's, BMW's, Triumph's, Moto Guzzi's, Vespa's, have always got me home.
