Motorcycle Exhaust Decibel Testing

Maine has adopted a simple yet reliable testing procedure that allows motorcyclists to prove their bikes don’t violate Maine’s motor vehicle sound law, the American Motorcyclist Association (AMA) reports.

The American Motorcyclist Association (AMA) has developed model legislation for use by cities seeking a simple, consistent and economical way to deal with sound complaints related to on-highway motorcycles within the larger context of excessive sound from all sources.

The model legislation offers an objective method for municipal jurisdictions to evaluate motorcycle sound through science-based measurement.

On-highway riders and their bikes don’t have to be victims of questionable sound-level checks anymore, thanks to a new procedure developed by the Motorcycle Industry Council in partnership with SAE International, and adopted by the global association, known for establishing a wide range of motor vehicle standards.

The Society of Automotive Engineers (SAE) International has produced a simple, consistent and economical sound test standard that can be used to determine whether a streetbike (on-highway motorcycle) exhaust system emits excessive sound, the American Motorcyclist Association (AMA) reports.

The J2825 "Measurement of Exhaust Sound Pressure Levels of Stationary On-Highway Motorcycles," issued by the SAE in May, establishes instrumentation, test site, test conditions, procedures, measurements and sound level limits.
