Before on of my trips to Europe and looking for old BMW motorcycles, I would put an ad in Das Motorrad magazine. I would get answers by mail and go visit the more interesting bikes. This one was located way out in rural country. The only person who could speak English was a 10 year old girl. I didn’t find out how that happened. She translated for the owner of the farm. The bike was just leaning against a wall. The owner had ridden it as his only transportation. When he could afford better, it was just left. I was only a bit interested until she told me that is was a gift to me, an American. I graciously accepted it.
This bike ran fairly well, but we didn’t use it much for anything.
I also had a R20, or R23, but don’t remember what happened to it. I haven’t found a photo yet.
