Hangtown: Hangtown MX, Prairie City SVRA Under Threat - Cycle News
Washougal around 2005 spent over 6 figures monitoring noise levels to show compliance after not getting the conditional use permit approved.

I don't like loud bikes at all, but noise is just the easy target here. If it wasn't the noise it would be the dust, the traffic, etc.

Back in the old days Blue Ribbon Coalition's tag line was "Less Sound, More Ground". They knew that cutting a few db's meant less hassles with keeping riding areas open. A lot of folks ran dBsnorkel's on their 2-strokes.. still see them around once in a blue moon.

I run the infamous OEM perferated end cap on my 500 EXC. My bike is still plenty loud, but without the headache-inducing roar from the straight-through FMF racing pipe that originally came on it. Perf end cap still has a mean tone to it that sounds cool to me. I can still easily get the front wheel in the air just by twisting the throttle.
Also love how the factory KTMs sound this past year.

Lets be real here. Those stock KTM mufflers sound like pure trash...Made worse by the horrendously lean tune from the factor to pass emissions.

I like the idea of quiet bikes, but you will not convince me that they sound good.

This is ignorant!! The week before, or the week after Supercross at nearly every venue. They have open header V8 monster trucks ripping in the same stadium and sound is not an issue.!! what are we doing here?

Agree this isn't an issue in stadiums. But even outdoor national tracks have legal issues & costs complying with noise laws.

And trickling down technology for all places to ride. Less sound = more ground.

Except how many stock exhausts stay on at local tracks. So many get dumped for the loudest fmf with no insert money can buy.

And that's why many tracks have been forced to close. Wasn't so much an issue back in the 2 stroke days.

I'm sure there are some examples but motocross tracks are located on purpose in very rural, sparsely populated areas where the land is cheap and loud motorcycles aren't bothering anyone. I've been to Glen Helen many times and it's right next to a prison maybe the inmates have been complaining too. With major manufacturers coming out with their e-bikes it won't take long before anything with a combustion engine will be banned and we all (not me) but everyone else is racing e-bikes and coming back to the pits to fire up their 120 db generator to recharge it.

AAAAHAHAHAHAHA 120 dB generator! Thanks, I needed that! Never change, Vital!

For reference, here's a 2.2 MW generator that's 76 dBA at 7 meters. It can be put on a trailer and fast charge over 300 Vargs simultaneously at maximum charging rate 7 kW, while producing less than 1/4 the loudness of the new 109 dBA standard. (120 dB loudness is off by a factor of 21 times, and to fast charge 300 bikes at once.)

And when a developer comes in and builds homes a mile from the track, sells them all and leaves town with the money, and the taxpayers learn the noise Code and use it to shut down the track.
