Fans will see two-strokes at Billown this year - at both the Post-T.T. and Southern 100 road race meetings.
A few weeks ago, organisers appealed to 125cc and 250cc competitors to enter the races as soon as possible.
Numbers have dwindled in recent years but there has been enough interest shown in the classes to ensure they continue around the 4.25 mile circuit in the south of the island.
It has also been announced that the Steam Packet Company is to continue sponsoring the Southern 100 International meeting in July.
