Eugene Laverty is leaving the World Superbike Championship to race in MotoGP next year.
The 28-year-old Toomebridge rider, who has 13 World Superbike victories, has yet to confirm which MotoGP team he will be competing with.
Laverty won this season's opening race in Australia with Crescent Suzuki but has struggled since and lies seventh in the 2014 series.
His brother Michael competes in MotoGP with the Paul Bird Motorsport team.
"We still have two rounds remaining and my aim is to climb back up on that rostrum before I move to MotoGP in 2015," said Eugene.
