After a third place in 2000, Eriksson edged Mika Ahola by one point to take his fifth world title in 2001. Eriksson continued with Husqvarna until the 2008 season, when he signed to the Bayerische Motoren Werke team with a contract that runs through 2010.
He then moved to Husqvarna for the 1996 season, and won the 400 cc world championship. Debuting in the 500 cc category, Eriksson finished second to Kari Tiainen, and then beat him to the title in 1998 and 1999, despite not matching the Finn"s win totals. After winning the 500 cc world championship for the fourth time in 2002, he moved to the smaller 450 cc class for the 2003 season and became a seven-time world champion, equalling Tiainen"s record.
