I think it's very important not to ignore strange noises in vehicles.
Coincidentally my car recently developed a whining noise. Dealer said it was a wheel bearing. Before it could be repaired another strange noise appeared - a clicking noise in fourth gear. Long story short. DSG gearbox knackered. New one required. One month out of warranty £5800! Got some good will so am paying (reluctantly) £580.
Fortunately the BMW GS has over 2 and 3/4 years of warranty remaining so plenty of time for the problem to become terminal, like the car, and be repaired.
Can I live with the strange noise? I feel there is not a lot I can do about it. I hear it every time I ride the bike. It's annoying but the rest of the bike is so good I try to ignore it.
Frankly speaking, not only from a mechanical perspective, health wise these sounds shouldn’t be ‘ignored’ by riders and more importantly BMW. Right out of the dealership the 1250 grated on my hearing. Informed the dealer that I was finding it difficult ride and if they knew a fix, and was told, to ride it out to the first service and see if it improves.
Now, having to deal with Tinnitus from one late night ride where the sound was so piercingly painful I had to stop the bike. A lot of reading since and I understand that permanent Tinnitus can be triggered from one traumatic event.
For all the Company’s safety hype, DBC, etc. there is no dialogue on the impact of sound—perhaps intentionally. The decibel rating stuck to the inside of the steering column confirms the Company is aware of it, maybe from a legal perspective, but at no time did the dealer point this out in the the walk around. And you don’t see ear plugs listed in the catalog.
If the Company is truly going to care for its riders, it needs to make more effort to better inform its dealers, be part of forums like this, and address issues like Tinnitus. So that others don’t end up asking the same question that I now do everyday, ‘Do I really want to ride today?’
