A new 800 cc basic Boxer model was launched in 1984 as a favourably priced alternative in the mid-range, below the price level of the new K models. This model was specifically designed to retain the custom of Boxer fans, and the design harked back to the last great Boxer motorcycles. The frame and chassis of this new BMW R 80 were put through a comprehensive upgrade to secure their modern profile. The most obvious feature was the frame concept derived from the G/S with single swing arm (Monolever) that had already proved its worth. Conversely, the basic concept of the telescopic fork and the new front-wheel disc brake originated from the K Series.
