Why does the motercycle loud? REEEEARRRR?

[MJ12]

But seriously, I have a serious question about motorcycles. I am talking about the... Harley Davidson looking ones? The Choppers? You know, those big ones, not the crotch rocket Japanese ones.

Very often when someone leaves a store parking lot on one, or when one is driving down the street, all of the sudden they'll rev it up and it makes the most ear piercing sound. I've worked with a lot of power tools, and they can be loud and annoying... but damn, those big motorcycles are f*cking annoying.

So since I know nothing about motorcycles, I was wondering, is it necessary to do that? Does it help it really get going? Or is it something people do to look "badass"? Like, "Hey, I'm an Emerican, born and raised on the USA"

...Or is it a bit of both?

 

[VirusType2]

They do that because they hate you

Never again will I call you handsome.

Bit of both. At a stop, sometimes it's neccessary to keep the engine revved to avoid engine complatency and to ultimately avoid stalling. What i think you're talking about is a change down in gear whilst on the move right? (that's when a rider kicks it down and gives it a handful of throttle to increase accelleration for one reason or another, sometimes to get ahead of a stupid driver or maybe to close the gap ahead)
The loud noise is the high revving of the engine as the motor kicks into a lower gear and the revvs are too high for the gear. Just a normal thing on any motor vehicle. You know when you're driving your mums car and you change down to decellerate before a set of lights, and you use the engine brake to slow the car down? Just like that, you're forcing the engine to naturally equalise the revs and by doing so you're slowing the vehicle down. The loud throbbing noise is the high revs of the engine, either created for a neccessary purpose or not. The bike is made for the intent of being loud, which is one reason they have pissant silencers on em, or even none at all. Bikes like that have intense engine pressures, pretty amazing that the machines aren't pissin oil after a dismount.

That being said, the bike is built entirely for the scene and to look "cool" and i think you'll find most assholes revving the engine to ignorantly gain attention. It's not uncommon to see a bloke riding one of em to dismount and pull a pair of plugs from his ears. Not suitable for long rides, for me it's about an hour before i'm so rattled by the vibrations and noise that i think "Well, **** that!"

It's part of the appeal, I guess.

lol

It's the bike that says 'Bad Mother****er' on it.

 

[Kula Meenur]

It's the bike that all experienced motorcyclists have no respect for.


It's all about the image. Riding a bike is much, much more about the image. If you centre your riding exprience around your image you'll end up assuming room temperature.

Hmm, I understand more now, but is it necessary for manufactures to make them this way? Or is it something they continue to do because it's what they are known for/what most people want?
Because those Japanese ones don't make that much noise compared to the Choppers. Of course assuming they have a different engine/way of making them.

If you centre your riding exprience around your image you'll end up assuming room temperature.

Lol, I do not understand this line.

Lol, I do not understand this line.

room temperature, lol it's a funny way of saying 'you will end up dead'

You're dead and no longer have a steady 98.7 ish degree core temperature.

Lol, let me put it another way...chop chop riders are the scene kids of the motorcycle world. Manufacturers do make it this way yes. There is an attraction that some men feel with having a bike that sounds big and powerful, so the manufacturers style the bikes to better suit what the consumer wants.

To answer your question in a more direct manner, it's not neccessary for the manufacturers to make them loud, they make them loud for the consumer because that is what they desire out of a specific model of bike.

Take for instance a 1942 Harley WLA "Wallah". Built seventy odd years ago. This model was a decent bike, quite heavy on the engine yet the engine noise it created was definately nowhere as loud as a modern Harley today. Brilliant machine, considered to be a very balanced bike (dad was rebuilding one back home when i was a young'un). As time progressed the scene change and bikes were modified to be loud and noisy (by changing the size of the extractors and/or muffler/silencer). Now in modern times, the bikes are manufactured on the consumers expectations to be loud, powerful and noisy.

Now take another bike, say a Honda Goldwing 1800cc. Much larger engine capacity than that of most scene bikes, and it's flat six. The manufacturer built it with a shaft drive instead of a chain drive and installed some of the biggest internal silencers to the machine i've ever seen. Because of this the bike is quiet as **** and has been nicknamed by riders around Perth as the "Whispering Death". Now if the manufacturer's intent had been to make the bike noisy, then they wouldn't have made modifications to it's design and engine config to make it quieter.

Bottom line is: the technology for silence is out there, but because the particular chop chop scene is the way it is, the technology not used.

Lol, I do not understand this line.

Lol Virus is bang on, you'll end up with a toe tag. The main indefinite cause of death for motorcylcists is inexperience. Riders hop on a bike, get confident then come guts up because they don't know what they're doing. I feel that this may be caused by the attraction to the lifestyle and not the actual pleasure of riding itself. So, when i see a kid on the road wearing a $1200 dollar racing helmet, knee plates and a back plate who clearly doesn't know a thing about riding, i feel that he/she may just be a future statistic. Many young kids get into it because they think it's cool, but to state an obvious point it's about as dangerous as ****. Any rider'll tell you that, even the novices.

Is that what they call, "jake braking"?

They do that because they hate you

...and this^

Chopper bikers, (especially many Harley bikers) don't like people like ZT who are annoyed by the ear piercing sounds of their motorcycles, and thus many of them like to have straight pipes and rev-up in busy suburbs just to piss them off.

 

[Kula Meenur]

I'm not sure using the engine brake is called jake braking? We just say "kick it down a cog" over here lol





edit: out of interest i googled it...apprently it is so... Awesome

 

[VirusType2]

Is that what they call, "jake braking"?

Technically, it's called 'engine braking'


Most people just say 'down shift'

lol

I'm not familiar with Jake braking, though it sounds like a legit street term


Also, you don't put a comma before the quotations to specify a word or sequence of words. See above

Are you saying only when quoting someone else should one use commas? Yes sir grammar police, I'll glady accept my citation.

well, I'm not an English expert or anything, but that usage just struck me as odd. Better fix it now before you get a bad habit.


I'm pretty sure that you use quotes like these examples.

example 1:

So, I said to that bitch, "If you can't keep your mouth shut, then you might as well put my dick in it."


example 2:

Anyway, to fix your problem, type 'delete Windows Vista' in the run box, and hit enter.

Ah, okay, it's much more clear now. Thanks.



But do they really like to rev it up in the suburbs to piss people off? D:

 

[Qonfused]

Yes they do.

In case you are unaware of this, many riders feel it's much safer to have a loud bike so that other drivers are aware of their presence. Bikes are easily hidden by blind spots.

In some ways true, but any rider who uses noise for this purpose is lazy. A bike rider should have to work to be seen, not rely on another mode for visibility.

oh so true cookie monster

Ah, okay, it's much more clear now. Thanks.

Welcome mate I personally don't think they do. My brother also lives across the road from the Gypsy Jokers bikie stead and it's pretty quiet. The bikies are polite and courteous as well and even muck around playing football with the kids on the street!
