Bremgarten has not hosted an official motorsport event since 1955, when spectator racing sports, with the exception of hillclimbing and rallying, were banned in Switzerland in reaction to the 1955 Le Mans disaster.
On June 6, 2007 an amendment to lift the ban was passed by the lower house of the Swiss parliament, 97 in favour and 77 opposed.
In August 1931 the Bern (Swiss) Grand Prix took place and the Irish motorcyclist Stanley Woods won the 500cc event on a Norton.
The Bremgarten Circuit was one of the original rounds of the Grand Prix motorcycle World Championship during the inaugural season of 1949 and from 1951 to 1954.
Famous riders who raced here included: Hans Stärkle [de; nl], Freddie Frith and Geoff Duke.
