Hey, Roger, if you're hankering after a BMW for "touring" (somehow I can't
picture you riding in the rain with a bedroll and tent packed on the
luggage rack), you can get into a "real" BMW for the price of the brake
upgrade on your next V8. There are lots of Slash-Five cycles from the
early 1970s around and BMW never made a better tourer.
