The 1980 BMW R 100
1980 BMW R 100 sits in the middle of BMW's air-cooled boxer touring lineup, the sensible, do-everything alternative to the sportier S and RS variants wearing the same engine. This is a bike built for covering real distance rather than chasing lap times: the shaft drive means no chain maintenance on long trips, and the boxer twin's low center of gravity makes it stable fully loaded with luggage. Power delivery is unhurried and torque-driven, rewarding riders who plan ahead rather than ride aggressively through corners. It feels mechanical in a good way, an honest machine you maintain yourself rather than plug into a diagnostic computer. The 1980 model carried over without significant mechanical changes from the prior year, so buyers comparing it to a 1979 example should focus on mileage, service history, and condition rather than spec differences. Today's buyer is typically a rider who has owned Japanese fours and wants something with more character and a stronger enthusiast community, or a long-term BMW owner adding an air-cooled boxer to the stable. Collector interest sits at a reasonable moderate-to-high level, with clean, well-documented 1980 BMW R 100 examples holding value better than average touring bikes of the era.
