Even BMW's legendary bikes began to lose lifetime as they all seemed to change to the go-faster, sell cheaper mantra of making bikes that can't make it "to the ton" without extreme care.
You are ill-informed and ignorant of the depth of the BMW bike market. I’d wager there are more BMWs Airheads with well over 100k miles on them than there are SOHCs. That does not even begin to include the K and R model line-up. Their boxer engine is one of the most durable, easy to service, and long living motors made.
I’ve got an ‘87 triple with over 260k miles on the original engine, never rebuilt as an example. It is capable to this day of two-up riding with hard bags for a cross country trip at a moments notice. Quality bikes and sturdy like a forged hammer.
Back in the 70s I met this Austrian BMW mechanic in the Sahara desert. He rode a Russian Dnjepr in which he had fitted a BMW boxer. In the sidecar he had even a little refrigarator built in. At the campfire we discussed bikes and I asked him which one
I should buy, if I ever wanted one.
'Not a BMW', he replied to my surprise, 'we're almost finished'. He was referring to rumors that BMW seriously considered ending the manufacture of motorcycles all together and return to small cars again. In the opinion of the Austrian mechanic BMW would not be able to catch up anymore. Well, look where they are now.
"If I were you, I'd opt for one of the CBFours." When back in Amsterdam, I asked a restorer of British twoseaters. He gave me more or less the same answer: don't buy British. If you want a
reliable bike, have a Honda Four.
Now, there's
durability and there's
reliability and people often mix these up. Yes, boxers can go a long way, but what if every 40.000 km or so you have to take the engine apart for a small 25 cents seal pissing oil? What about cold starts? BMW's were notorious for bad starting, as I also found out when I rode one in British Columbia for a week. And I had made sure everything was up to spec. BTW, have you ever tried to set the ignition on one of them old boxers? Did you like the compromise?
Recently I read an article about the technical aspects of that recently released big boxer (1600cc or so?) in a magazine for professionals in the automotive branche. In it BMW's press release was cited in which the company proudly proclaimed they had projected its technical life for a ton. Are you kidding me? Nowadays every Japanese bike over 500cc is expected to do 3 tons with just regular maintenance.
Is there something good to say about BMW? Certainly, the K75 has a very good reputation and, btw, much better than the earlier K100. But that info is from hearsay, knowing the AA and BMW mecs in the workshops.
My CB500 has been with me since 1980 and apart from flat tyres, it has died en route only once. In torrential rain the ignition (probably the plugs) was soaked. Next morning, without me having done anything, it started right up again. Another event that I have described here in this forum, was the failure of the
IGN SWITCH right before entering a tunnel. Luckily just by fiddling the key, I was able to make it home. So far my report on reliability and I guess my 43 years experience is enough to be
well-informed. The bike is 47 years old, btw.
