I had that same bike and a 1972 R50/5. The R50/5 was a bargain at the dealer. It was the BMW “3rd world bike” ran on regular gas and was as smooth as silk. No demand in the U.S. for the “slowest” BMW. I put 123,000 miles on that bike.I had a r60/6 1974.....I wish I still had the bike...BMW made a great bike...
