Contrary to the general trend and although sales figures had been declining significantly since the mid-1950s, BMW presented a revised model range at the Cologne International Bicycle and Motorcycle Exhibition. This was indeed expanded by an additional 500 Series sports model. The BMW R 50 touring model in the 500 Series was replaced by the slightly modified BMW R 50/2 and this went on to become the most successful full-swing model by the time production came to an end in 1969 after a production run of more than 19,000 units sold.
