1972 BMW R50/5 Motorcycle Batteries

In 1972 the only significant change to the R50/5, other than styling, was the lightening of the flywheel.  Because there was no stock electronic ignition system in the R50, the only R50/5 bikes with battery ignition were converted to it later. Different people may have put different sized batteries in customized trays, but the most common battery boxes and batteries for BMW’s at the time were the probable choice, and are what is listed here. Please measure your battery or battery box before buying one of the batteries listed here.
