William Dunlop will ride for the Wilson Craig Honda Racing team at this year's TT.
The Ballymoney rider competed for the Londonderry-based outfit at last season's Sunflower Trophy meeting, so the move is not totally unexpected.
It means Wilson Craig, which supported Guy Martin at TT 2010, will be mounting a twin assault on the mountain course, with Dunlop riding alongside Australian teammate Cameron Donald.
