Riders will compete in a number of displacement- and skill-based classes for competitors on vintage motorcycles.
Practice will start at 8:30 with races to follow. We should be done by 11:30 so that practice day can start on time. There will be class structuring changes for the vintage and post vintage classes.
Vintage and Post Vintage classes and modern support classes will be running on a special Vintage GP track. There is no membership required for this event.
