Targeting bike with loud exhausts

[carver]

What's this I hear (in true hearsay form of course) from those in blue that Harleys with straight-throughs (and anything else on 2 wheels that is "too loud") are being targeted for being too loud.

Thanks to years of media attention to and the noisy misbehaviour of idiot tossers in poofy little wet pants jap cars with blow dryers for exhausts that they take the noise issue out on us bikers.

Bikes SHOULD be loud. Loud and beautiful beasts of all makes and models as long as it has two wheels!

to be truly tested, it must be tested in a sound chamber

i have a vtr1000 with two brothers exhausts which just got through a warrant,like you say your throttle is also your noise control the more you give it the louder it goes!

My VTR passed (standard pipes that have had the bafflectomy) passed and did an unofficial test was 95-96db.

Has a nice burble to it nice deep rumble and not the highier frequency putter sound...(which is alot harsher on the ears) the guys at the shop said sounds nice... and they didn't find it offensive...

I agree... to get a true and accurate reading, no surrounding noise, no echo etc...

Under 100dB on a motorcycle is the (new) rule. Do you fully understand just how loud that is? There's not many that will go over that.
My 750 Srad with it's Yoshi TRS is only 87dB at the required revs

Alot of HD's will fail that! They did a test on a standard one and it was over 100!!

also the cars notice a noisy bike and hence can not say they did not see you!

By what divine right should bikes be allowed noise pollution when nothing else, either on wheels or not, is allowed to make noise that exceeds 85dB/100dB?

Bikes are allowed to be louder for the simple reason that cages have the room for longer pipes, where on a bike it is pretty restrictive... but at the end of the day depends what you call offensive and what I call offensive and what some nambey pambey in Wellington calls offensive...

Frenceny has a lot to do with it as well... the lower the rumble and frequency you would be supprised that most people don't find offensive... the highier closer to that screaming sound they do...

The business across the road the owner is in some car v8 club thing and I am sure that it is more than 90db cars are allowed... (well I reckon it be louder than the vtr) but I personally like the sound of it... (except when he be tunning and reving it at 11pm... )

You want motorcycling to get a bad name? You want ALL motorcyclist to be tarred with the "boy racer" label? You want ALL bikers to be thought of as a big fat hairy anti-social sub-class? Go right ahead and ride noisy bikes making the maximum noise from open pipes and open throttle.

you mean we ain't already there...

i feel sorry for any DRZ-sm owner with aftermarket pipes....

my one was very loud!

all singles are hard to keep quiet

yeah but for the test I doubt you would need to rev it to 7500 rpm..

Stupid LTSA ruining how a bike should sound

[Rob Taylor]

Just got a warrant on my Heritage with after market slash cuts with minimil baffles.No problems at all,the noise didnt bother them and i think its loud...

[naphazoline]

it's probably been mentioned at least once in here somewhere,but i think that bikes should have a louder limit then other vehicles,simply for the safety factor.(and they sound good too)

LOUD PIPES SAVE LIVES.
and it's good to know that other motorists can hear you coming.cause they sure is hell don't make an effort to see you coming.

My wife's Buell XB12S was due for a WOF and 16k service, so we took it to Road & Sport about 2 weeks ago. We did an "informal" noise test in their carpark, and even with the race kit the bike registered 99db. They were happy with that, and so were we.

And from personal experience it's been shown to be bullshit

Believe my std race kit zorst has 105dba stamped on it, don't know what standard that's quoted for though. It's not obnoxious, as you know, but it's good to know they can sneak under the limit.
