Additional Notes

  • All three AWO variants — the AWO 425, AWO 425 S, and AWO 425 T — share an identical manual transmission fluid capacity of 1.1 liters, indicating a consistent gearbox design across the model family.
  • The 1.1-liter figure represents a service fill capacity, meaning the amount of fluid required during a standard transmission service rather than a full overhaul rebuild.
  • The Simson AWO 425, produced from 1950-1953, carries the same 1.1-liter transmission capacity as the later AWO 425 T (1954-1960) and AWO 425 S (1955-1962), suggesting mechanical continuity in the transmission unit across successive variants.
  • All three configurations list normal as the use condition tied to the 1.1-liter capacity specification, meaning the figure applies to standard operating conditions rather than a severe-duty service scenario.
