Manx riders Conor Cummins and Dan Kneen will be competing at the Macau Grand Prix next month.
Thirty-one competitors from 13 nations will be on the grid for the far east event.
Cummins will be aboard the Tyco Suzuki superbike - he finished a very close 2nd in the race in 2009 behind Stuart Easton.
Kneen will be riding the Marks Bloom Racing Suzuki as he returns to Macau having made his debut in 2010.
Current Champion Michael Rutter will be looking for an unprecedented 8th victory but will face stiff opposition from the likes of John McGuinness, Gary Johnson, James Hillier and Martin Jessopp.
