Ballymoney brothers Michael and William Dunlop are to race at the Macau Grand Prix for the first time in November.
Their father, the late Robert Dunlop, won the event in 1989.
William will ride Wilson Craig's Honda Superbike, with Michael on the works Paul Bird Motorsport Kawasaki ZX-10.
Stuart Easton winner of the last three races at Macau, on the south-east coast of China, is absent after being badly injured at the North-West 200.
Crumlin's Stephen Thompson will ride for the British Superbike SMT Honda team alongside John McGuinness.
Thompson was the only Northern Ireland rider at the 2010 race, retiring on the third lap because of a blown engine.
The Macau GP will be staged on a 3.8-mile public roads course on Saturday, 19 November.
The last winner from Northern Ireland was Phillip McCallen in 1996.
