In 1973, BMW launched the advanced /6 Series. The new BMW R 60/6 replaced the R 50/5 as the entry-level model. The R60/6 retained conventional drum brakes on the front wheel to keep the sales price down, and the slide carburettor controlling the fuel supply process was also retained. The motorcycle also featured innovations: five-speed gearbox, new instrument cockpit and new controls. In spite of all the features, the R 60/6 was not viewed as particularly modern when it was launched in the marketplace. Nevertheless, 13, 511 machines were sold to private customers and the loyal customer base of government agencies.
