No they don't. Thats how a lot of them are built. If a car driver cannot see a motorbike. They should not be on the road. Your car engine would be quite loud if it was not fastened in a box.
Serious question. Why ride a motorbike so fast, without being able to hear approaching traffic due to the loud noise coming from the engine.

If you are driving “so fast” the only approaching traffic will be oncoming or from side roads.
People with loud pipes say that

I'm thinking more of motorists, etc who can't see an approaching motorbike due to them having their view restricted by buildings, trees, high sided wagons etc. Not those who could see the motorbike, but choose not to!

Except you cant hear their annoying voices or annoying attitudes over their ****ing annoying exhaust noise. They can **** OFF!!!!

A very cogent point Accy, equally applicable to any other legal roaduser, those that can see ,but choose not to.
None so blind. That the cannot see.

Whilst riding a motorbike at any speed it is mostly wind noise that you hear, and it is loud enough to be a hazard such that wearing earplugs is very strongly advisable. Even with offensively loud exhausts I doubt the rider would hear much of the engine whilst underway however annoying to anyone else.
I should stress I just had the factory pipes on mine albeit it was likely louder than a car because the engine was less enclosed, but still, it's wind noise you hear whilst riding along

The olde FJ1200 was the first bike to failmUK government noises tests because opening it hard from a roll-on in second caused it to wheelspjn past the microphone. Manufacturers dodge this by designing the torque curve to get them through the test without any undue grief.

Yep my mate had one and it was incredible, bought from Chris Vincent's shop in Earl Shilton it was one of Chris' personal bikes and had been 'got at' slightly (gas flowed and the airbox restrictors cut away)

When noise regulations first came in to law the BMW flat twin bikes the Police rode didn't comply.

And didnt need too as it was deemed that they were similar enough to the older twins that they could be sold in the UK on the original Type Approval for a certain number of near (something tells me 6 years, but memory very hazy.)
Owned a ex Met 1977 R80/7 for a while so had all the gen that came with it.

The dB measure is only if any use if measured in real use conditions. I'm not up on the current tests but a long time ago when my company designed a special pipe that met noise related regulations but behaved like a straight through race pipe in real terms use with the associated noise.
It got around by meeting the noise regs at the power or revs and speeds the noise tests were done at. I remember they tested on a colleague's bike on the industrial estate owned by the company. I once helped the tech director test it for noise on a ride past.
These pipes were only designed for iirc the fastest of road legal bikes. IIRC one model was called a fireblade but that was a long time ago. It involved modifying the power profile too with some kit needed. Whilst it was legal the pipe was excessively loud in use except when idling at low speeds. I was told that meant lower revs than the high revving bike would be used IRL.
So now when I hear that excessively loud pipes it might not be from a non road legal race pipe. Personally I think it is highly possible to make a bike pipe that isn't excessively noisy at any time in its use. It's just that I doubt some bikers would agree with that. I would love for all bikes to be 77dB or less at all times in use but I suspect even legal ones go well above that with certain revs in normal use.

Yeah I know they didn't need to but the point is you'd be hard pressed to find a more civilised bike in terms of racket. Certain magazines at the time (Bike and Superbike for sure) used the Police bikes as an example of how ludicrous the new regs were along with the Fj 12 which you quoted earlier (and I have personal experience of) not passing when that was one of the quietest most civilised bikes around (til you gave it the beans)
The original question was
I don’t agree with noisy pipes saving lives but as a motorcycle rider and cyclist we spend most of our time avoiding cars pulling out in front of us. This Is almost a daily occurrence for me as I commute on my bicycle.
So whilst I don’t use noisy exhausts on my motorcycle I completely understand the rationale.
Why are car/van drivers not looking where they are going ?
and
Why do car/van drivers pull out in front of cycles/motorcycles?
Too many distractions radio/phone/passengers
Not taking responsibility seriously of being in control of a potential killer
There are probably too many factors to list, but the primary cause is many car/van drivers don’t care enough. As a rough guide the advanced driver and rider group I belong to has at least three times as many motorcylists as drivers looking to improve road safety.

Motorcycle riders, hear, see and smell their surroundings much more than car drivers, even with full face helmets and noisy engine/exhausts.I don’t agree with noisy pipes saving lives but as a motorcycle rider and cyclist we spend most of our time avoiding cars pulling out in front of us.
