'''RT 125''' can refer to a model of [[Two-stroke cycle|two-stroke]] [[motorcycle]] made by [[DKW]] in Zschopau in the 1930s, Industrieverband Fahrzeugbau and [[MZ Motorrad- und Zweiradwerk GmbH|MZ]] in the 1950s and early 1960s, and [[DKW]] in Ingolstadt in the 1950s and 1960s. "RT" stands for "Reichstyp" or "National Model".
The '''RT 125''' was a model of [[Two-stroke cycle|two-stroke]] [[motorcycle]] made by [[DKW]] in Zschopau in the 1930s, Industrieverband Fahrzeugbau and [[MZ Motorrad- und Zweiradwerk GmbH|MZ]] in the 1950s and early 1960s, and [[DKW]] in Ingolstadt in the 1950s and 1960s. "RT" stands for "Reichstyp" or "National Model".


In the 1930s DKW pioneered the Schnurle [[Two-stroke cycle|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 port]]s. 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.

The '''[[DKW]] RT125E''' was a single cylinder, two-stroke Road [[motorcycle]] produced by [[DKW]] between 1952 and 1973. It could reach a top speed of 75 mph (120 km/h). Claimed [[horsepower]] was 16.63 HP (12.4 KW) @ 7500 RPM. 
==Engine==
The engine was a [[air cooled]] single cylinder, two-stroke. A 54.0mm [[bore]] x 54.0mm [[stroke]] result in a [[displacement]] of just 124.0 cubic centimeters. Fuel was supplied via a [[port]] control. 
==Drive==
The bike has a 6-speed transmission. Power was moderated via the wet multiplate. 
==Chassis==
It came with a 2.75-17 front [[tire]] and a 3.00-17 rear tire. Stopping was achieved via expanding brake in the front and a expanding brake in the rear. The front suspension was a  telescopic fork while the rear was equipped with a none. The RT125E was fitted with a 2.77 Gallon (10.50 Liters) fuel tank. The bike weighed just 189.6 pounds (86.0 Kg).
