The RT 125 was a German two-stroke motorcycle made by DKW in Zschopau in the 1930’s; “RT” stands for “Reichstyp” or “National Model”. DKW pioneered the Schnürle two-stroke loop scavenging process to dispense with the use of a deflector piston and improve efficiency of the combustion chamber. DKW also developed a highly efficient arrangement of transfer ports. These two features were included in the RT 125 to great commercial advantage. Competitor companies such as Adler and TWN copied the adoption of flat-topped pistons and strove to develop equally transfer port arrangements without infringing DKW’s patent.
A great example of DKW engineering and how it disrupted markets at the time. This motorbike retains its original beauty and is surely an opportunity not to be missed.
