The 1972 BMW R 50-5
1972 BMW R 50-5 sits at the entry point of BMW's /5 series, the smallest-displacement shaft-drive twin in a lineup built around long-distance comfort rather than outright speed. This is a bike that rewards patience: the boxer engine spins up smoothly, the shaft drive means no chain maintenance interrupting your riding season, and the whole machine feels engineered for covering distance rather than showing off. Handling is stable and predictable, better suited to open roads and touring routes than aggressive cornering, and the riding position keeps you upright and comfortable across a full day in the saddle. The 1972 model carried over without significant mechanical changes from the prior year — buyers comparing it to a 1971 example should focus on mileage, service history, and condition rather than spec differences. Owners tend to be riders who've moved past modern bikes chasing performance numbers and want something mechanically honest, easy to maintain, and pleasant on backroads. Collector interest sits at a moderate level, drawing buyers who want a usable classic rather than a garage ornament, and a well-sorted 1972 BMW R 50-5 remains genuinely rideable today.
