Michael Schumacher has reportedly sold his kart track at his birthplace Kerpen to his younger brother Ralf.
Germany's Sport Bild reports that the name of the venue will however remain 'Michael Schumacher Kart and Event Center'.
An insider told the magazine: "Michael is completely focused on formula one. For this reason he would no longer have had enough time to devote to the kart center.
"With Ralf, however, at least it (the track) stays in the family," the insider added.
Ralf Schumacher, who races with Mercedes-Benz in the DTM series, already owns a well-known German kart track in Bispingen.
