The track marshals informed us at the end of 2022 that they can hardly read the start numbers of motorbikes passing the track marshal at high speed and going flat through the corner. Information such as overtaking under yellow or exceeding the track limits can then no longer be passed on to race control/race director.
For this reason riders should carry out their start numbers according to the IDC regulations in 2023.
