John McGuinness will ride for the Paul Bird-managed Stobart Honda team at this year's Ulster Grand Prix at Dundrod. BBC Sport exclusively revealed on 6 July that talks were taking place between the multiple TT winner and the Cumbrian businessman following a test.
McGuinness is also likely to ride in the Supersport and Superstock races on separate machinery at the event which runs from 10-13 August.
He parted company with the AIM Yamaha team at the start of July.
