After more than ten years absence from the MotoGP World Championship it was announced late in 2004 that the Laguna Seca circuit would once again features on the 2005 race calendar. The US event was excluded back in 1994 due to track safety concerns and limited crowd attendance figures, despite continued success with the World Superbike Championship. However since signing the agreement with MotoGP, which cemented the return of the US GP, a significant investment has been made to improve track safety and the circuit facilities. Combined with increased interest in the championship buy the US public Laguna Seca is now promising to be a spectacular affair. However, unlike any other race in the championship, the 2005 US GP will only feature the MotoGP class from the regular schedule, with the GP250 and 125 classes being replaced by local AMA events including the AMA Superbikes.
