Cameron Donald has renewed his contract with Norton Motorcycles for the 2015 Isle of Man TT races.
According to the team, the two-time TT winner from Australia will compete in both the opening Superbike and Senior races in June.
Donald said: "Norton is synonymous with the Isle of Man TT and I can't wait to ride the newly developed SG3 round the Mountain Course."
The 37-year-old claimed both his TT wins at the 2008 event.
He added: "After a solid but frustrating 2014 where we made great progress with the bike but didn't show it's full potential we all agreed to keep the team together for 2015.
"We're all looking forward to a great TT."
Norton have renewed the services of both Mick Grant and Steve Plater to further develop the SG3 Norton in 2015.
