There will still be three races as previously although the 'Ultra-Lightweight Classes' have been dropped due to the decreasing number of entries year on year.
The 125cc/400cc event will be replaced with an Open Race for solo machines up to 1100cc.
The revised Race Programme will now be:
Race 1 600cc Supersport
Race 2 650cc/250cc SuperTwin / Lightweight
Race 3 1100cc Superbike
However, the Ultra-Lightweight, 125cc & 400cc classes will be retained at the Steam Packet Southern 100 International Road Races, where competitors will as in previous years enjoy two races around the 4.25-mile Billown Course between 7th & 10th July.
Regulations and Entry Forms will be available for all three races organised by Southern 100 Racing early.
