German motorcycle Grand Prix
[1] The first two Großer Preis von Deutschland races were held at Berlin's AVUS before moving to the new the purpose-built Nürburgring which was used in its full 28 km configuration.The Solitudering near Stuttgart had a challenging layout and due to proximity of a major city, the crowds were large, but the narrow roads had to be widened.There, the lesser known 7.7 km Südschleife was used twice, as in the Eifelrennen races which often attracted international entrants, but that part of the track was not rebuilt in 1970/71; thus in the even years from 1970 to 1980, the famous Nordschleife was used.The East German brand MZ had made groundbreaking progress in two stroke technology, but due to defecting personnel and other problems, they fell behind in the late 1960s.[2] To prevent further "demonstrations", the East German politicians, otherwise eager to gain international recognition, sacrificed the event's World Championship status, limiting entry of riders from Western states from 1972 onwards.
