stupid vn rule

[vn_lexcen_s2]

this little thing has been in my head for a few weeks now and i cant figure out a reasonable explanation. so i thought you guys could help me set it straight.

its the rule about the vn being under the 92db noise level. i mean when you think about it thats fair enough. coz when you get higher than that i think it starts to sound yuk.......

but what about when it physically hurts to be crossing the street when a harley davidson goes past..they are loud as all f**K. then you think about the 92db the vn is under and you ask yourself why me and not those fu**en crotch rockets....its irritating.

anybody know what the deal is. why other things are louder than others.

cheers
matt

I dono but i know what you saying. A few doors down a bloke has a harley that just has a straight pipe and dam that things loud. You can hear it a km away.

[xcop5l]

i think it has somthing to do with how the car/bike is sent out of the factory

[Christina]

i seriousssllyyy HATE motorbike NOISE, of any sort (sorry i know people love them on here).. but seriously, the noise is like someone farting 20 times over, constantly in ur ear, it's worse than a 90' corolla with a 10" exhaust tip

[Kid_Random]

my mate had a loud as series 2 rx7...
alot of people compared the noise to a harley

[immortality]

we have the same problem over here, the cops can sticker you (defect) if they think it's louder then standard and it's then up to you to prove it's not. harley's standard exhausts are louder then what the max we are allowed to have. go figure. our laws are based on the "boy racer" problem with there ricers etc and we get caught in the cross fire

Its actually 90db and its not just VN's, its all passenger cars since 1983... This is Australia wide too, as these are rules set in the ADR's and the Vehicle Standards, not state specific guidelines...

The exhaust systems on vehicles manufactured on or after 1st January, 1974 must at the time of first registration comply with ADR 28 - Motor Vehicle Noise.
In service all vehicles must comply with the Road Traffic (Vehicle Standards) Rules 1999 Part 10 Division 3 – Noise Emissions.
For passenger cars, derivates and panel vans manufactured on or after 1 January 1983 the stationary noise level when tested must not exceed 90 dB(A).

It is recognised by authorities that a loud exhaust is a safety feature on a bike(makes sure people driving cars know that they are there) but you have to call it quits at some point. I think the cops dont hand tickets to harley riders cause they dont want to start shit with the biker gangs. Its plainly obvious that the cops will only pick on the people that wont stand up as a group to defend themselves. Just look at when there are riots, the cops wont arrest people for fear of escalating the situation. Why should the rest of us that dont have a mob mentality be punished and the people causing the real problems get away with it.

end rant.

I dont think upsetting bikies is relevant here. Not everyone that rides a harley is a bikey. Police wont mess with clubs like the Finks, Hells Angels, Rebels, Gypsy Jokers and the rest but im sure it has nothing to do with not handing out tickets to individuals riding harley davidsons.

Then why have I never seen one pulled over for excessive noise, ive seen the cops go past them on numerous occasions and not pull them up. If someone has a better reason why they dont get pulled up im all ears, but ive seen it many times when I was younger doing laps and the cops pull over heaps of cars on and given night for machineries but the bikes never get pulled up.

[lieos]

i work for trivett ... largest prestige group in aus ... they just got a harley franchise which shares the workshop with peugeot who i work for from factory they are njot that loud they are loud when u put straight pipes one which u can order through factory. u can also get a NOS kit from factory.

[J_D]

They sound nice with standard pipes but the straight thrus are intrusive, must be over 120db.

[89vncommy]

I think you find that because Harley's come from the factory like that, that it is actually legal for them to be that loud. There is not the same emissions/noise filters on a bike, because you don't have the room to put it all ... There is no cat on a Harley, and any baffle on the bike exhaust to keep the noise down is in the pipe... Some people drill out the baffle in the exhaust to make it louder, and to the untrained eye, you would never be able to tell.. This is why the cops can't/wont do anything about them....

I am a bike rider (Jap sports bike) and I do hate the loudness of a Harley. I have a Yoshimura exhaust on my bike, and it is a little louder then the standard pipe. Motorcycles also have a butterfly clip in them, which stays shut under 3,000 rpm. This is to keep down emissions, and noise... But after 3,000 they open up ... By coincidence, the emissions & noise tests are performed below 3,000 rpm, so a stock bike will also pass ... (I know this is the case for my 2003/2004 Suzuki GSX-R1000)

From a safety point of view, I would like to make my bike louder, because there is not a day goes by that I am almost wiped off the road because a car driver is not paying attention to what they are doing... A little more noise would at least give them more of a chance to hear me ...

[daily_wagolis]

as stated before, cars from '83 have to keep under 90dB. from memory from when i got my test done, im pretty sure the limit for bikes was 96dB. that's a fair bit louder in terms of intensity than you think, being only 6dB

but most harleys are way above that figure anyway, so the question still stands...

[greenfoam]

Bike were loud from the factory, yep, in 1960. My IT 490 is almost deafning but it still passed the noise rules in 1984. How? Yamaha filled the exhaust pipe with a restrictor. It's just a big washer of course no one kept them in the bike for more than 10 seconds because they weren't suppose to be there at all

i have read this on the ask the copper threads and they reckon that noise rules for cars apply to bikes as well, so 92db for cars its 92db for bikes as well.
most coppers just dont pull them over.

Bikes are pre Feb 1985 100db
after Feb 1985 94db

[VNCalais98K]

Meh... harleys shit me to tears... i wouldnt be sad to see every single one turned into scrap.
They dont look good
They dont have style
They dont go particularly fast
They dont handle that well
They sound like crap
People riding them are generally clinically retarded.

Ok.. maybe the last one was an exaggeration.
But it just annoys me when your minding your business and all of a sudden you get the crap scared out of you as some wankstain blasts past on a harley and rattles your fillings out with their shitcan exhaust.

Although i admit, it was pretty good seeing the cruise go through town the other day.

[vt1538]

I would rather hear a tough V twin go past than a rotary with a hairdryer. They sound like Freddy Mercury farting into a fan.

[VNCalais98K]

Hmm, depends on the rotor.
The Series 6-8 with a nice turbo on it sounds good... the old series 1-2 pieces of NA shite sound like a bowl of nuts.

[greenfoam]

Talking about harleys I like the V-ROD but I wouldn't own one, that's the only one I like and I really like the sound of a rotary at 10,000 rpm

[VNCalais98K]

Yeah... on my VN the redline is basically where i can kiss goodbye the engine...
On my mates S2 13B rotary, the redline is just a reminder that youre going really fast....

[SweetWagon]

Talking about harleys I like the V-ROD but I wouldn't own one, that's the only one I like and I really like the sound of a rotary at 10,000 rpm

Or a F1 car at 20,000 rpm. Take a looksy at this

Man dont you read Its 90db not 92 and motorbikes arent covered by ADR 28... They have their own seperate rules.
