Ian Hutchinson will ride for Yamaha at TT 2011.
The rider who created history last year by winning all five solo races has signed for the next two seasons.
Hutchinson, who is currently recovering from a serious leg injury, has a total of eight victories on the mountain course.
Yamaha will also be celebrating its 50th anniversary and will be competing at the Isle of Man with full factory bikes for the first time since 1972.
Race team manager Shaun Muir is delighted with the whole package:
