For another five years, at least until the end of 2016, the German MotoGP will continue to be staged at the Sachsenring.
The circuit's place on the 2012 MotoGP calendar had initially been in doubt, but the event was later confirmed as round eight of this year's championship and the new long-term deal was announced on Friday at Assen.
ADAC in Munich and motorcycle world championship promoter Dorna Sports signed a contract stating that the Sachsenring Management GmbH (Ltd.) will be the organiser whilst, in 2012, the ADAC Saxonia will be responsible for the sporting issues.
“Over the past 10 years, the Sachsenring has become Germany's mecca of motorbike racing, and the circuit will maintain this reputation in the future, thanks to our new contract," said ADAC Sport President Hermann Tomczyk. "The Sachsenring Management GmbH will be a reliable and committed partner."
Saxony's Prime Minister Stanislaw Tillich added: “It was the explicit aim of Saxony's administration that the motorcycle grand prix remained at the Sachsenring, and this will be our target also in the future."
On average, more than 210,000 spectators have attended the Sachsenring motorcycle grand prix races over the past 10 years, making it one of the most popular sport events in Germany.
“MotoGP is extremely happy with the new agreement reached with ADAC. We think that Sachsering is the best-equipped circuit to host the German GP in the future," said Dorna Sports CEO Carmelo Ezpeleta.
"We also welcome the opportunities the parties involved have given us to reach so many fans of two-wheel racing. This deal is very much in the interest of motorcycling.
"And this year, Germany's passionate racing fans can see current Moto2 World Champion Stefan Bradl race in the MotoGP category, where he is currently achieving great results despite it being his first season in the premier-class category."
This year's German MotoGP will be held from July 6-8.
