Rossi will start his 2013 pre-season preparations alongside his MotoGP rivals at Sepang from February 5-7.
Fellow Italian Andrea Dovizioso is taking Rossi's place at Ducati, which was purchased last year by Audi, part of the huge Volkswagen Group.
In a recent Crash.net
poll asking fans 'What will be considered a success for Rossi in 2013?' the most popular option selected was 'multiple race wins', which received 57% of the vote.
