Tyco TAS Suzuki riders Guy Martin and Conor Cummins are set to compete at the Armoy national road races in July.
Cummins is keen to get some track time under his belt ahead of the Ulster Grand Prix after sustaining a wrist injury at the North West 200 in May.
Lincolnshire rider Martin has been a regular visitor to the County Antrim circuit in recent years.
The pair will face stiff competition from local riders Ryan Farquhar and Michael and William Dunlop.
Michael Pearson will also be on the grid for the event on 27 and 28 July.
A record prize fund of £15,880 will be on offer for the 10-race programme.
An additional attraction will be a parade lap by the JPS Norton which was ridden so successfully by Robert Dunlop in the early 1990s.
