 A Chinese variant of the M-72, the Yangtze River 750, has been in production since 1957.In 1954 a small number of modified R75 models were produced at Eisenach (then in Soviet-controlled East Germany) for testing under the designation AWO 700, but were not put into full production.The success and reliability of the shaft-driven R75 during the war led to the US Army requesting that Harley-Davidson produce a similar shaft-driven cycle for American troops.
