After a much-publicised disagreement with T.T. organisers, Milwaukee Yamaha will compete at the 2014 meeting.
That means a return to racing around the Mountain Course for eight-time winner Ian Hutchinson and fastest-ever newcomer Josh Brookes.
Sponsors Milwaukee withdrew sponsorship of Shaun Muir's team for the T.T. only - in a dispute over new engine management system rules.
Milwaukee felt it would put Yamaha at a distinct disadvantage against other manufacturers.
So why the change of heart?
