The International Motorcycling Federation has reduced maximum sound levels for off-road competitions.
The FIM has also lowered maximum noise level regulations for 2010.
For Motocross and Track racing, the maximum noise from 100 metres will be 81 dBA while Enduro noise levels will capped at 78 dBA from 100 metres. Overall, maximum noise levels will be reduced 3-6 dBA from 2009 regulations.
The FIM has also established a new standard sound test for competitions.
The “2 metre max” method will be used to measure sound levels at 2010 FIM Motocross, Enduro and Track World Championships. The test is carried out by positioning a sound meter at a 45 degree angle two meters from the exhaust. Sound levels are to be tested at the engines’ maximum rpm.
“A major step has been made with the implementation of this new method, thanks to an excellent cooperation between manufacturers and promoters, not to mention the strong impulse given by the Danish federation (DMU),” says Jean-Pierre Mougin, FIM deputy president and chairman of the steering committee on sound level reduction.
“This is important for the survival of all FIM off-road disciplines. The FIM had to react effectively. 2010 will constitute a first step in the fight against noise nuisances and the results will define the future actions.”
The new regulations were developed under an agreement the FIM signed with the United Nations Environment Programme in December 2006, and has the support of manufacturers and promoters.
“For the past 15 years, FIM has become a leading sporting federation, actively involved in the study and application of solutions to fight against environmental nuisance,” says Vito Ippolito, FIM president.
“The rules of the new sound test method for competition, represents a significant progress. I’m really pleased with the collaboration with our partners to achieve this agreement.”
