The Mighty ST1300 has started to develop a humming, perhaps drumming, noise at around 100km/h. Hard to know the source, but I'm guessing rear wheel. I have asked my motorcycle mechanic to check it out, he is pretty busy at the moment, so looking (asking) for some input in the meantime.
My thoughts are rear wheel bearing, and whilst that will be an exensive replacement, anything else is likely to be more expensive.
Whilst at another local motorcycle shop (a few parts and accessories, mainly service and repairs) on Thursday, I asked the owner / chief mechanic. His advice was that this is a commonly known noise with the ST1300, and that it was nothing to worry about. As I've never heard of this previously, I'm thinking is this advice plausible? On the other hand, he could've said "wheel bearing or crown & pinion gear wear", got a repair job and pocketed some $$ - so perhaps his opinion is plausible.
Any thoughts fom the brains trust here?
