We have a town that used to be motorcycle friendly. Then the rich decided it was detrimental to their property values. They write for over 80db. I was written up with stock federal compliant exhaust. Challenged the ticket and the method used for taking the noise sample. I won, turns out up till that point there was no standard written for taking the sample and therfore no way to certify the result.
(I did the Euro compliance for an OEM so they could export to the EU and was fully aware of the equipment and procedures for both DOT and EU testing at the time.)
BTW, the bike I was riding at that time maxed out at 74db under acceleration from 35mph in 3rd gear using all the standards for testing applicable in 2004 when this happened.

 

none of my bikes would pass,,,, thay are all loud, & I love it........

 

Golly, there goes my trip to Aspen. Next time anyones up there ask them how's their aspen....

This thread was started 1.5yrs ago. Somebody is really bored.

 

Motor carrier noise emissions. A State may regulate levels of environmental noise or the use, operation or movement of any product if EPA determines that such regulation is necessitated by special local conditions and is not in conflict with regulations under this section. NCA § 18(c)(2); 42 U.S.C. § 4917(c)(2).

(note - unfortunately this only applies to carriers)

 

Colorado is NOT a motorcycle friendly state. In Denver you can get a $500 fine for not having an EPA stamp on your pipes. As for dB meters, my town tried that but quickly learned you can't pin point a sound, all you can do is measure ALL the sound coming from a particular direction. So now it's up the officers discretion.

 

I did not belive and now I do...

Aspen set to approve motorcycle noise campaign

Aspen City Council is being asked to approve a $2,000 spending package that would be used to launch a campaign against motorcycle noise in Aspen.

If approved, the supplemental appropriation will fund new signs at both of Aspen’s entrances informing people about Aspen’s noise ordinance, which sets the maximum noise limit at 80 decibels for a moving motorcycle. The campaign will also feature printed leaflets, buttons and bumper stickers “with a logo representing a quiet Aspen” to be distributed to the public, and tent cards to be placed in the rooms and lobbies of area hotels. The campaign will also feature bulletins on GrassRoots TV.

The request is coming from the city’s environmental health department, but the city was agitated into action by Susan O’Neal, a citizen who has become fed up with motorcycle noise over the years. O’Neal lives on Durant Avenue, which is a popular cruise for motorcyclists in the summertime.

Under the banner of “Operation Quiet Aspen,” she spent much of last summer trying to inform the motorcycle driving population about the noise ordinance. O’Neal’s cause also received support from Councilman J.E. DeVilbiss, who told Aspen police last summer to crack down on motorcyclists who were unnecessarily revving their engines.

Earlier this winter, O’Neal requested that she be put in charge of Aspen’s anti-noise campaign. Although it looks now as though the efforts will be directed through the environmental health department, O’Neal, or any other citizen, will be able to assist with the distribution of the stickers, buttons and flyers.

“Staff appreciates suggestions from the public on ways to get the word out, and we have also been directed by the city manager to use discretion and approach ‘Operation Quiet Aspen’ in a way that is not only effective at informing ... but maintains a welcoming atmosphere for our guests and residents,” a memo about the program from the environmental health department said.

 

I believe that over half of the posts on here during winter months would register over 100db with all the whining, tattle tales and bs that takes place. I may even start a 100 db'r club and wear a patch.
