American Honda backs 109 dB sound limit for 2027 racing season
American Honda has voiced its support for a new 109-decibel sound limit that will take effect during the 2027 AMA Supercross, AMA Pro Motocross and SuperMotocross Championships.

The regulation, a three-decibel reduction from the previous 112-decibel limit, was advocated for by manufacturers competing in the series and is also supported by the SMX League, AMA Pro Racing and the American Motorcyclist Association. The new standard will bring U.S. professional motocross racing in line with the sound limit already used in the FIM MXGP series.
Honda said the change is intended to help preserve access to motocross tracks and off-road riding areas by addressing noise concerns from surrounding communities. Maintaining access to those facilities remains an important issue for the long-term health of the sport.
“Honda is committed to making a positive impact on society, and we recognize that maintaining access to off-road riding areas is essential to the future of our sport,” said Brandon Wilson, manager of racing and experiential at American Honda in a news release. “While the AMA’s updated standard initially applies to professional competition, developments at the highest levels of racing inevitably influence the broader riding community.”
Wilson added that the lower sound limit balances performance with responsibility and could help ensure continued access to motocross facilities for future generations.
The change also offers manufacturing and development benefits by aligning U.S. competition with international sound regulations. Honda said a common specification will help manufacturers streamline motorcycle development and production while benefiting teams and riders competing in multiple championships.
For the 2027 model year, Honda plans to produce and sell motorcycles eligible for the series that meet the new 109-decibel requirement. The three-decibel reduction is expected to have a more substantial impact on noise levels at greater distances, according to Honda, potentially benefiting tracks and nearby communities.
To help with the transition, American Honda also plans to provide technical assistance to privateer riders and support teams during the early rounds of the 2027 AMA Supercross season.
