I read the AMA article. When any claim is preceded by the words "may be" it tells me that there isn't any definative evidence. Not saying I'm not open to the idea that it "may" but then so would chewing gum also draw upon your energy reserves as would breathing, heart pumping...blah blah blah.
The motorcycle noise issue is strictly $$ driven. Excessive noise is, has, and always will be a relative term. Be it exhaust, music or someones mother in law.

Actually, going up this afternoon. Her bike won't be ready, adding bags and windshield that won't be here until next week. Going to put it on the trailer, I'm not about to try to ride in this frigid weather. You know I'm a fair weather rider! Want to come up with us?

I don't understand what you mean by the $$ driven part.
And....
While excessive noise may be relative to you, noise is measured.
It is measured in units called decibels (dB).
Table 1. Sound intensity levels.
Decibel Level (dB) Source
140 threshold of pain: gunshot, siren at 100 feet
135 jet take off, amplified music
120 chain saw, jack hammer, snowmobile
100 tractor, farm equipment, power saw
90 OSHA limit - hearing damage if excessive exposure to noise levels above 90 dB
85 inside acoustically insulated tractor cab
75 average radio, vacuum cleaner
60 normal conversation
45 rustling leaves, soft music
30 whisper
15 threshold of hearing
0 acute threshold of hearing - weakest sound

The decibel is a measurement of sound not noise.
Noise is unwanted sound no matter what the decibel.
My stand on the excessive noise issue being $$ driven is based on what I see and hear by the lobbyists. When I see the big companies advocating "noise restriction" out of one side of their mouth and voiding warranties for purchase of after market exhaust pipes and yet selling almost exact versions of "custom" exhaust under their own lable, I have to be skeptical of their true intent. Is it to keep noise emissions down and the reputation of motorcyclists positive or to protect their own market niche.

Ok noise is relative then because although I think rap music is noise it is good sound, still can't call it music, to others. So noise is sound we don't like, therefore any level of noise is undesireable and an exessive amount is unacceptable.Roughidle said:
Decibel is the measurement of the amplitude of sound waves. Doesn't descriminate, that is up to us.

I only know of 2 bike mfrs that market an "off road" exhaust, Harley and Triumph. While ther's not a lot of after market options for a new Triumph exhaust, I'd have to agree that Harley is trying to protect their sales by offering a illegal exhaust system.Roughidle said:

Stats are stats.. you can't change the numbers..Pete said:
Maybe I'll go back and read the article just to make sure my number is right, and see who did the research to determine the number. Does anyone offer any research to the contrary?? Hard accident numbers, loud bikes are in LESS accidents??

1. Lying through statistics makes tons of people a living and promotes an ass load of agendas.itsbob said:
2. Your statement is totally incorrect. Bikes with modified exhausts "may" be involved in 34% more accidents but that does not mean YOU have a 34% higher chance of an accident. I ride my bike safely and defensively. I use the same traits whether I am riding a stock exhaust bike or a modified one therefore MY chance of an accident is EXACTLY the same regardless.
