The Manx Telecom Post T.T. Road Races will feature three eight-lap races.
Organisers have announced the programme at Billown on Saturday 12th June.
There will be a 125cc/400cc run concurrently as a two class race, a 250cc and 650cc Twins run the same way and a Supersport race.
The actual timing of road closures has yet to be finalised but the Southern 100 Club is promising a break of 45 minutes between the practice and race sessions.
