The first Dutch TT was held on Saturday 11 July 1925. In those days there wasn’t any ‘real’ race track; the races were held on the public road. The 28.4 km triangle of roads between Rolde (start/finish), Borger and Schoonloo served as the race track.
The organiser was the ‘Assen & Omstreken’ motorcycle club, established in 1922.
