Sound Testing


The AMSA and its Partners can and will test Motorcycles for sound output. The best way to ensure you pass is to have a properly packed (ideally this is something that occurs more often than ice ages) stock muffler. Some stock exhausts may not have a spark arrestor, which is required for riding on Crown lands. An aftermarket tip, or exhaust systems like FMFs “Q4” (four stroke) or “Q” (2-stroke) are great alternatives. Many aftermarket exhausts have quiet insert/spark arrestor combos that are cheap, and easily installed for riding off road.

The testing procedure adopted in 2013 is the FIM style WOT test. MX bikes, particularly 4-strokes, may not pass without a well-packed muffler, or stock style exhaust. Please leave the “shorty” mufflers at the track (are they even welcome there anymore?)

There is no doubt that races are a focal point of the community. It’s also an easy chance for other groups to make shots at us, so let’s do our best to not give them a chance.
