context_section_description: RT 125: 1939–1962 and 2000-today
  ES125/150 Pressed steel frame with Earles type front suspension. Four speed, six volt, pre-mix.
  ES250 : Utilized a pressed steel body with Earles type front suspension.
  ETS250 : Sports version of the ES but with more traditional type of tank and telescopic forks. The distinctive 5 imperial gallons (23 l; 6.0 US gal) fuel tank makes this model a desirable classic motorcycle.
  TS125/150 : Direct descendants of the RT125, and the last MZs to use "premix" fuel and a 6-volt electrical system.
  TS250: Developed from the ES/ETS machines but with a new frame. The engine hung from the top beam pivoting at the rear with no front down tube. Early models were four-speed machines with the vertical finned cylinder head but the later machines had the flat top engine and five-speed gear box, the basis of the later models. These models were all 6-volt and pre-mix fuel.
  ETZ250 : The first road going MZ to include a disk front brake and automatic oil injection. There has been a special model ETZ250A which equipped the GDR's army and has been exported to several countries of the former east block.
  ETZ251 : Derived from the ETZ250 but with modifications to the motor and chassis. A 300 cc version was also marketed.
  ETZ125/150 : Similar to the ETZ251 in appearance but with an updated 125/150 motor, now with the flat-topped cylinder head, five-speed gearbox and autolube. The design of the engine was still derived from the original DKW design, apparent from the concentric kick start and gear lever arrangement.
  500R : MZ's first four-stroke motorcycle, essentially an ETZ251 with a Rotax 500 cc engine fitted, although the engine was no longer rubber mounted and a front down tube provided extra support.
  MZ Skorpion:  The 500 cc Rotax engine used on the Seymour-Powell designed prototype was replaced with a 660 cc Yamaha water-cooled engine on the production vehicle.
  MZ 1000S:  MZ's biggest bike, and their first "in-house" four-stroke engine. The MZ 1000S is the most powerful inline twin cylinder engine worldwide.
