MMZ (ММЗ) or Moskovskiy Mototsikletniy Zavod (Московский Мотоциклетний Завод) was a motorcycle manufacturer, based in Moscow. It commenced operations in 1941 building the M-72, a Soviet licensed copy of the BMW R71. With the German Invasion of the Soviet Union, the plant was transferred east to the town of Irbit in the Ural region. The new plant was known as "IMZ" (ИМЗ) or Irbitskiy Mototsikletniy Zavod (Ирбитский Мотоциклетный Завод).
In 1946, the Moscow plant was re-established to manufacture the M-1A Moskva, (the DKW RT 125 taken as war reparations). In 1951 the plant was relocated to MMVZ (ММВЗ) or Minsk Motovelo Zavod (Минский Мотовелозавод) in what is now Belarus.
