Entries for this year’s Southern 100 races have opened ahead of action returning to the Billown Circuit in July.
Regulations and entry forms are now available via the official website.
The meeting will take place on Monday 6, Tuesday 7, Wednesday 8 and Thursday 9 July, bringing top class road racing action back to the Motor Isle Billown Course.
Entries are again invited from Next Generation Supersport machines. Under these regulations, all machines must utilise standardised electronic control units (ECUs) and comply with balancing measures including rev limits, minimum weight requirements and performance parity adjustments.
Southern 100 Racing said: “These measures are designed to allow a wider range of machine configurations to compete on equal footing, enhancing both competition and spectacle.”
For 2026, the Lightweight races will also incorporate Sportbike machines in accordance with 2025 MCRCB regulations, broadening the class and adding further interest to the racing programme.
Southern 100 Racing said it looks forward to “welcoming competitors, teams and fans both familiar faces and newcomers alike to the Motor Isle Billown Course for another exciting year of racing”.
Entries close on Sunday May 31.
