Overview
The 2004 season was the 25th edition of the Sidecarcross World Championship. It resulted in a third world championship for Daniël Willemsen, his second in a row with passenger Kaspars Stupelis. Five time world champion Kristers Sergis, with Sven Verbrugge as his passenger, was their main rival early on in the competition. An injury to Sergis meant however, the pair would miss five race weekends and be out of contention for the championship. After this, Willemsen and Stupelis won the championship almost undisputed with second-placed Marko Happich more than 150 points behind in second place. For the following season, 2005, Willemsen and Sergis would exchange passenger, with Sven Verbrugge returning to Willemsen, who he had raced with before, while Sergis and Stupelis would form an all-Latvian team.

The fourteen GP's of the season were held in eleven countries, Spain, France (2x), Netherlands, Germany (2x), Italy, Estonia, Latvia (2x), Croatia, Bulgaria, Russia and Belgium. It was the first time that a GP was to be held in Russia.
