Dear all,
I inform you of the regulations which were communicated to me by video conference by the Director of Sports of the FFM, these being applicable from January 1, 2024 to all motorcycles used on circuits whatever their age or engine capacity.
The sound level control will be exclusively dynamic. To do this, the company Azimut Monitoring equips all the circuits of sound meters placed at the edge of the track so as to record motorcycles at full speed, during practice, timed sessions and races. The system developed over 2 years simulates the noise coming out of the exhaust with an application of 3 corrections. The standard not to be exceeded is set at 109 db. The offense is noted if a machine exceeds 109 db more than 3 times.
After having exchanged with several officials and participants during this video conference, it appears to me that it would be wise to perform private tests on cinrcuit before a first race to know the noise level of your motorcycle, in order to correct it if necessary. I add that it may be useful to plan firstly a noise attenuator to attach to the end of the exhaust.
The president of the F.F.M. speed commission whom I questioned on this subject told me that all circuits would be equipped from January 1, 2024. You can nevertheless make sure before traveling.
Good luck with this preparation. See you soon at the Assembly.
Philippe Fréon
Proclassic President
