2025 Street Rs

Your picture isn't very clear, maybe you could post a better close in one?

If its like a blister under the coating then it would be down to surface preparation. I spoke with a very experienced powder coater friend of mine and he said quite often it's either poor surface prep I.e. oxide removal via vapor blasting, or it's time stored between preparation and final coating.
My 900 st has a few blisters under the coating with no chips or external reason obvious for it to happen, hence my discussion with him about it.

 

Eldon calls it right, there are a lot of owners complaining about the same issue. The same thing happened to my machine, thankfully, it was only the sump, it was easy to take off, and I completely stripped it down to the alloy, then sprayed it with high-temperature paint (primer and top coat) that matches the original finish. I have mentioned before that the QC appears very poor at present, it was not the same when all the machines were made at Hinckley. I would take it back to the dealer to look at it if it's still in warranty, at least then you have it recorded, should it get any worse.

 

Interesting what @Eldon and @Iceman say which presented a rabbit hole from my working days in the construction industry where the contract would have a defects liability period (warranty).

Depending on how the contract was executed, Under hand or as a deed the contract terms would be enforceable for 6 or 12 years respectively, irrespective of the contracted construction duration, at the end of which the defects liability period would commence, usually 12 months.

However there may be defects which subsequently arise that could not have been seen or discovered through reasonable inspection because they are hidden or non-apparent. These are termed Latent Defects as opposed to Patent Defects and recourse may be pursued during the life of the contract, depending on method of execution and up to 3 years thereafter.

The 1980 Limitation Act gives the claimant up to 3 years from first knowledge of the defect in which to make their claim. Thus 12+3 =15 years from contract execution. Many prudent contractors will carry Latent Defects insurance cover.

With the purchase of a motorcycle It is somewhat different in timescales and onus of proof here in the UK.

0-6 Months: The law presumes the defect existed at delivery, placing the burden on the trader to prove otherwise.

6 Months - 6 Years: The burden of proof shifts to the consumer to prove the fault was present at the time of sale.

Food for thought.

 

I'd suggest those lines are casting marks and nothing to worry about.
Yes they could've been finished better prior to painting but that costs and as we all know, things are getting trimmed (excuse the pun) to the bear minimum.

Continous improvement my ar5e!

A case in point, I bought the wife a new watch the other week, not a cheapo either. The colour coordinated strap has been cut so short that the last hole doesn't have enough overlap to stay in the retainer wrap.
I now need to buy another strap to make it workable

 

Just for reference, this is mine (24 plate)

 

Evening mate—yeah, I’ve seen similar on a few triples before. Sometimes what looks like blistering on the engine case can actually be minor casting imperfections or slightly uneven paint from the factory, especially in less visible areas. If it’s not flaking off or showing signs of corrosion underneath, it’s usually nothing to worry about.

That said, keep an eye on it—if it starts getting worse, bubbling more, or showing bare metal, it might be worth getting it checked under warranty (if applicable) or at least cleaned and protected to stop any potential corrosion.

Once you upload a clearer pic, people here will be able to give a more accurate opinion
