I still sometimes ponder getting another BMW, but the main problem with BMW's for me is the sparse dealer support network in the U.S. That might not be so in Europe, but I never ride there.
I loved my BMW's until the last one, a 1990 K75, left me stranded in Wyoming with stripped splines. I lost my devotion to the marque then and there. Guess how many BMW dealers there are in Wyoming.
I suspect the older BMW's had fewer problems, giving rise to a cadre of owners who knew they had the ultimate in dependable motorcycles. In 1970, when I rode for Metro, in D.C., the company had its own shop, and they kept my work-issued R 69 US running fine. With a kick starter, magneto and low compression engine, there wasn't really that much to deal with on those /2's besides tires and oil. They had a backup bike in the garage, though, just in case.
During the '80's, my ride in Richmond, Va., was a '74 R90/6, and the closest shop was Morton's, about 50 miles north. That R-bike was easy for me to maintain on my own, but it ate up brake light switches at about one per year, and it had a quirky habit of occasionally dowsing its headlight for a few seconds, making for trying moments on dark country roads in Goochland County. I had to ride up to Morton's to get spendy replacement switches, points and condensers, and valve cover gaskets, and I never bothered to find out what was happening with the headlight. Fortunately, it never turned off when there was a cop around.
Out here in Northern Arizona, support for BMW's is on and off. Here, you have to find a specialist to get your tires changed if you don't have your own garage. Indie shops come and go here, and right now, the best place to get a Beemer fixed is at the Yamaha dealer, where they have a fine mechanic who is also a Beemophile. Even he doesn't seem to care for working on the newer ones. Otherwise, the closest BMW place is about 150 miles away.
Thanks, anyway, but I'll stick with my FJR for now. For about 80K miles, it has never given me a problem. WBill
