The SAE J2825 Sound Test for Motorcycles

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 (MIC) in partnership with SAE International, and the Motorcycle & Moped Industry Council (MMIC), as one of its funding partners.

The MIC and the Society of Automotive Engineers (SAE) established the SAE J 2825 sound test, which will provide a quick, easy, economical, and science-based tool for accurately identifying motorcycles with excessively noisy sound emissions.

Now, law-enforcement authorities have a simple, quick, economical tool for accurately identifying motorcycles with excessively loud exhaust systems. The SAE document J2825, “Measurement of Exhaust Sound Pressure Levels of Stationary On-Highway Motorcycles,” meets the need for a practical, consistent roadside sound test.

MMIC and its member manufacturers and distributors recommend the new SAE J 2825 stationary sound test procedure for on-highway motorcycles and encourage the implementation of these standards across Canada.
