It will fit, they are the same except for color. Husaberg 2000 to current will fit KTM from 2000 to current rear wheels. The front wheels from KTM 2000 -2002 will fir Husaberg 2000-2003, KTM 2003 to current will fit Husaberg 2004 to current. KTM hubs are a powdercoated dull gold color from 2003 to 2007, Husaberg are silver powdercoated. I hope this is not too confusing.
Cheers,
