“Having a girder frame constructed of V-section pressed steel, the Mass motor cycle is interesting as showing the trend of design in Germany. The transmission throughout is entirely enclosed by the frame, and the drive is through two internal expanding clutches. A 7½hp flat twin forms the power unit, the flywheel of which is provided with four blades to assist cooling. A handle is fitted in lieu of a kick starter, and engages on the end of the camshaft on the near side of the machine. This design is illustrated as a matter of general interest, as showing the trend of thought in the land of our late enemy.” From 1920 volume of Motor Cycle (29 April)
