Mar-Train Racing have signed a two-year deal to become the official Yamaha UK Road Race team.
The Lisburn-based team has pulled out of the British Supersport championship, where Alastair Seeley raced their YZF-R6 Yamaha to second place this year.
Mar-Train will compete at the North West 200, Isle of Man TT, Ulster GP and selected national road races.
The team will consist of one rider and will campaign in the Supersport, Superstock and Superbike classes.
Mar-Train said they they expect to announce the name of the rider in the coming weeks.
The local team enjoyed three consecutive seasons in the British Supersport series, including a championship success with Stuart Easton in 2013.
They also took in the three international road races this year.
"To be the official Yamaha UK entrant is a fantastic accolade for a family run team such as ourselves," said team principal Tim Martin.
"We have had a strong relationship with Yamaha UK over the past four years, winning two dozen British Supersport races and a North West 200 on the fantastic YZF-R6 plus numerous other national victories.
"Having the security of a two year deal shows Yamaha's intentions and commitment to the project, and also their confidence that we can put their machines on the top step at the international events.
"This is a fresh and exciting challenge for us and one I am relishing - 2015 cannot come soon enough."
