So many threads concerning "noises"

Purchased my '05 3 years ago completely aware these bikes make noises like no other bike I have ever owned. Until the Japanese bikes came along, noises were the norm in the motorized 2 wheel universe. Maybe the solution to noisy BMWs is to trade them in on Hondas. I love my "noises" and will not swap it for a Honda. Sorry to read about the expectations and displeasure. They are of a different culture.... and unlike the rest of the bike universe. IMNSHO.

To that end, have the BMW’s gotten louder...or have I just gotten older?

I used to have a KTM which, compared to my previous Hondas, sounded like a bag of nails but never made an extra (knocking) sound under load. As I have said before on my thread, a engine that knocks under load should not be ignored unless there is a very good reason. It appears that, at long last, an explanation has come to light (see 'Strange R1250GS engine noise' thread).

Some people also "love" to undergo some physical torture while lovemaking. That is evidently their right.
I don't however and hate hearing that unpleasiant and abnormal noise every time I ride my brand-new expensive R1250GS.

An unpleasant noise is not necessarily abnormal, and even an abnormal noise (in the sense that most of the vehicles don't emit it) isn't necessarily a sign of anything actually wrong (in the sense of causing damage or shortening the vehicle's service life).

Story I heard from a Harley tech many years ago: the Evolution motor was designed in the days of high-priced, low-octane gas, and so was intended to run on regular (87 octane). The simple two-curve vacuum advance system (low vacuum triggers a switch to a less-advanced rpm-vs-advance curve) had the quirk that it would generate a fraction of a second's worth of spark rattle if you rolled the throttle on in a wimpy manner. The factory said this was harmless, and the three Evos I owned that all went well over 100,000 miles.

The tech told me people kept bringing their bikes in and complaining about "engine knock." After a road test, they'd be told this is normal, it's not going to damage anything. This didn't go down well--"I didn't spend all this money for a bike that makes funny noises!" So the factory said, fine, you don't want to hear this perfectly normal sound, then fill it up with premium (91 octane) gas. This made customers happy. Eventually, the company started listing premium as the required gas for the late Evos and Twin Cams--not because the engine needed it (an engine with 8.5:1 compression does not need 91 octane fuel), but because that was the easiest way to keep customers from complaining about "funny noises."

Whizzy brakes, no FD drain plug, what's not to like?

Again, in your example ALL H-D of that type made the same "funny" noise because of a well documented and acceptable technical reason.

The "not funny at all" noise I am complaining about is only emitted by a very small (comparatively) number of R1250GS, and should NOT be there... I think this is a different case from your story .

I had 2 other liquid cooled R1200GS LC before and both emitted very loud mechanical noises , compared to my previous oil cooled GS's.

I did not complain about them, knowing what was the reason for it and because of the fact they ALL suffered from it.

My brand new R1250GS still emits all these mechanical noises (albeit at a lower volume) AND adds the new and abnormal (not intended) noise to it when slightly under stress... this I cannot accept.

So you have a decision to make. If your continued efforts to have a dealer acknowledge and fix the source of the noise are unfruitful, then you either live with the noise or sell the bike. Good luck.

It should not be there... according to whom? You obviously don't like it, and I can understand that. BMW, far as I know, has not yet issued a judgment on whether it's a sign of something wrong or just a noise that some portion of the bikes make. Remember that there is a difference between "average/median" and "in the acceptable range." Given that parts tend to be exponentially distributed, it's quite possible that a small fraction of bikes are within acceptable parameters but make a noise that most bikes don't. It remains to be seen whether this is the situation with the noise you describe. We are waiting on tenterhooks until somebody at BMW tells us what causes this noise, whether it's anything more than an unpleasant sound, and just what the heck "tenterhooks" are.

I would hazard a guess that you haven't heard this annoying strange noise. Apart from the exhaust and the wind this is the only other noise I can hear. The last time I was in this situation was when I had a 1978 Yamaha DT250. A crude air cooled two stroke which made a loud 'pinging' noise due to it's large cooling fins.

The R1250GS is a modern state of the art motorcycle and obviously this noise shouldn't exist. I feel that it is increasingly obvious that this problem is only occurring with some but not all 1250s. Probably a batch and I have drawn the short straw!!!
