The Ultra-Lightweight class at the Metzeler Post T.T. Races at Billown have been dropped from the programme.
The Southern 100 Club says it is due to the decreasing number of entries year on year.
There will still be three races as previously with an Open or Superbike Race bringing the meeting to a close after Supersport and Supertwin/Lightweight contests.
The Metzeler Post T.T. Races at Billown are due to take place on Saturday 7th June 2014 - the day after Senior race day at the end of T.T. fortnight.
