Test Example for SAE - J2825

As you know, The General is the “Quiet Warrior.” Since 1997, he has been on the cutting edge of advocating for sound education and appropriate enforcement of sound laws to address excessively loud motorcycle exhaust noise. He has helped sound tech as various OHV events throughout the country at areas ranging from the Stonyford OHV Area in Northern California to Loretta Lynn’s Ranch. Those events include working AMA National Enduros and Dual Sport Rides, Dealer “Sound Education Days”, major trail rides, and helping at sound clinics. On behalf of the BRC, he also runs the FMF/BRC Sound Testing Program for OHVs.

A number of the troops asked me to do a sample sound check on my bone stock 2001 Suzuki 1500 V-Twin Intruder using the test procedures of the SAE – J2825 20 inch sound test for street motorcycles.

Results for the 1500 Intruder:
Idle – 80.4 dBA
2000 rpm – 85.5 dBA

It appears this test procedure leaves plenty of room for healthy sounding aftermarket street exhaust systems, while screening out the obnoxiously loud street bikes.

This is a very good step for motorcycling!

New Sound Test for Street Bikes - SAE J2825

With so many issues hitting off-road riders these days (i.e. CA budget battle, travel management, etc), The General wanted to make sure that the troops are aware of a rather historic event in the saga of addressing excessively loud motorcycles.

I believe this is a game changer in the battle to improve the image of both the off-road and street motorcyclist. While the off-road community has the SAE-J1287 20 inch sound test – a standard that has been adopted by several states, the missing-link in the sound saga up until now has been an easily applied stationary sound test for street bikes.

While operating the FMF/BRC Sound Testing Program for OHVs at many AMA Dist. 36 Enduros or Dual Sports, I am often asked by dirt-bikers..."When is somebody going to do something about the loud street-bikes?" Well it looks like we have an answer.

Also, some riders don’t realize that the general public does not distinguish between loud dirt bikes vs. loud street bikes – they view all excessively loud motorcycles in the same manner.

I think the SAE-J2825 offers law enforcement and those of us in education a valuable tool to help the riders and other stakeholders address excessively loud street bikes.

Everybody wins with this new test. Kudos to all those who worked in the development of the

SAE-J2825 Sound Test!!!
