This was the first BMW to feature a single cylinder engine, establishing a tradition that would last until 1967 of there being at least one overhead valve single in the BMW range.
The new model incorporated features found on the twins, including unit construction for the engine and three speed gearbox and shaft drive. A pressed steel duplex frame equipped with pressed steel forks was employed again reflecting the larger machines. Developing 6 bhp the new model would remain in production until 1936 and formed the basis for later, larger displacement singles.
