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.
