William Dunlop hopeful of challenging for wins at Armoy and Dundrod

William Dunlop is hopeful of challenging for wins at Armoy and the Ulster Grand Prix after a "difficult" start to the season.

The elder of the racing brothers has been struggling with a dislocated shoulder sustained at the North West 200 and has also been adapting to his new Yamaha machinery.

The 27-year-old likes the Armoy circuit because it has "a bit of everything" and praises brother Michael for his achievement of winning four Isle of Man TTs in a week.
