It's an 2018 R nine t Urban G/S, BMW premium occasion with another 22 months of warranty.
So this would be a spray fault from the factory?.. i just noticed there's tiny blisters around the larger ones.
I dont know if this was already present when i got the bike 2 months ago.. i lifted the tank up yesterday for some wiring work and noticed the blisters.
Already searched the internet for the same problem on the R nine t range.. but did not find a single thing?
If it's still under warranty @Chris I'd suggest getting it back to the dealer for a claim, as it's deffo a defect under the paint.
When you had the tank up did you notice any grittyness or overspray on the underside of the tank, suggesting it has been refinished?
It's not that common, but vehicle manufacturers (especially cars) sometimes do minor paint repairs to chips or scratches caused on the production line......unfortunately not every brand new vehicle has perfect unmolested virgin paintwork when it leaves the factory.
If your bike was bought used, it could have been the dealer used a local paintshop to refinish the tank before putting it on sale if it had any blemishes, but without personally inspecting the tank, I wouldn't be able to say if the paint was factory or not.
As I suggested........go back to the dealer asap......that is only going to get worse, not better.........and the only remedy would be to strip off the paint back to metal and refinish......but I'd personally push for a brand new tank, not a new paint job.
