I live about 5 miles (on the same road) as the local Harley Davidson dealership and would love it if HD riders left the stock pipes on their bikes. While the engines do vibrate, don't dismiss the additional concussive force of an unmuffled exhaust.

Isn't there a legal limit on the amount of dB(A) produced by any vehicle?

(Switzerland here)

Yes, but they're surprisingly recent, so most vehicles are grandfathered into "may still make a shitload of noise" levels.

And that's the real reason. These toddler narcissists are out to make it known to the world that here rides a badass, not that there is someone who drives responsibly and whose life depends on the volume of their exhaust. It's pathetic.

It's not possible that they might just enjoy loud machines? And you might not enjoy loud machines?

I have neighbors, friends, and family who ride motorcycles either for the speed or for the sound. They're mostly reasonable about it. But the thing about loud machines is that they are loud for everyone, who didn't get to choose whether to listen to that engine at 2AM.

The comparison to toddlers is apt because we expect adults to be aware of the effects their actions have on others, and take steps to mitigate them in social reciprocity.

This doesn’t deserve to be downvoted. The statement is correct. I have a permanently destroyed right foot and ankle because someone made a left turn from the right lane just outside the Holland Tunnel in NJ back in 2004. The driver “didn’t see me” before making the illegal turn and planting his Mercedes horizontally across my lane as he slowed to enter the gas station driveway. I laid my quiet 800cc bike down and plo…

It sounds equivalent to driving your car around with the horn constantly pressed for safety. Why not get a horn or something for your bike? Or wouldn’t that sound as cool?

I've heard that there are indeed places in the world where people will refuse to drive if the horn is not working, for this reason.

Correct. My bike has a stock exhaust and sounds like a sewing machine, but I wear earplugs mostly to protect against the constant wind noise at speed.

Is that not accomplished by wearing a helmet? I haven't been on a motorcycle in over a decade, but I recall it being pretty quiet in the helmet.

No, there's more than enough noise to cause permanent hearing damage.

Obviously higher speeds=higher wind noise; you might be fine "Measurements of motorcycle riding noise levels vary, but are generally around 85-95 dB at speeds up to 35 mph, climbing to 110-116 dB at 65 mph"

I wonder. Can this same happen on a dashboard mounted phone in a car?

Dashboards are not bolted directly to engines. The issue is that motorcycle parts are more directly connected to the engine. Sportbikes normally use the engine as a structural member, bolting all the other bits and pieces to the engine block. So vibrations through motorcycle handlebars and such are more intense than those on the dash of even an extreme muscle car.

Before someone asks if this could be "fixed": This is a desirable trait. It improves the frame stiffness of the vehicle, resulting in better handling.

I would love to see statistics on how many tickets are issued per year for these violations. I suspect zero.

USA long-time motorcycle owner here: agree. I believe there have been laws on the books for many years regarding noise limits, but they are (effectively) NEVER enforced. No-muffler-at-all ("straight-pipe") exhausts on V-twin (EX: Harley Davidson and its countless clones) are de facto standard (and for reasons unclear to me are accepted).

Also, aftermarket exhaust systems for motorcycles (99.9% of these being much louder than stock/OEM) are a huge business: I'd guesstimate that 50% of motorcycles sold in the USA soon (< 1 year old) end up running aftermarket exhaust systems; it's a standard first modification done by almost all enthusiast owners.

Why would that be relevant or important? Frankly, it's not a justification for antisocial behaviour to 'like' it.

> Attaching your iPhone to vehicles with small-volume or electric engines, such as mopeds and scooters, may lead to comparatively lower-amplitude vibrations. No superbikes for you Apple users :D - recoils in anticipation of onslaught of downvotes - In all fairness I expect it's going to be difficult to design anything with such small delicate moving parts to be invulnerable to arbitrary frequency vibrations. It can a…

I keep my iPhone in my jacket pocket and use the bluetooth module on my helmet. I also have a Garmin GPS on the handebar of my touring bike, although in 2021 you can get GPS built right into the bike's instrument panel.

(To be fair, my most preferred navigation method on long trips is to tape a piece of paper with handwritten notes to the fuel tank anyway.)
