1932 Böhmerland 600cc


The duplex frame is made from tubular steel with vertical and horizontal reinforcing bars and resembles a drag bike frame from the 1980’s. Basic but strong in design its sheer length had enough space for a uniform dual seat behind the motor and a third seat above the rear wheel.


The main frames suspension consisted of a rigid tail section that was part of the main frame member and not a secondary piece. As such to make both steering and ride quality up to the high standards he set Liebisch had to create a unique and complex front end. The fork used tubular triangular blades with internal reinforcement elements that were welded to cross bridges. Short horizontal arms and the lower ends of the strong vertical springs were attached to the lower parts of the blades. The cantilever design mean both leading arms and the yoke were effectively sprung allowing for maximum control of the front wheel.


The single cylinder displaced some 598cc making it not unlike the thumper engines of KTM and Honda, where things get crazy is the bore and stroke ratio with a massive 120mm stroke and slim 79.8mm bore.
