1250 brake line corrosion.

[Traffic893]

From a different forum. I know this may have been covered but can’t find a thread.
2019 GS1250, 700 miles and the owner has noticed that bolts and brake lines are suffering, in his opinion, excessive corrosion. Took bike back to dealers who went along with it and reported back to BMW. BMW replied basically stating he has used the wrong stuff to wash the bike which has caused the corrosion case closed.
Owner states only been ridden in fine weather and rinsed in water, not been dirty enough for a full wash. Anyone else heard/ experienced this?

The fittings go dull, but corrode? Not on the two I've had.

Frankly, it's impossible to comment without some decent pics. Contamination from debris/fluids on the road is always a possibility - lime/cement/coolant for instance.

However, I think the response was pretty predicable TBH, probably just a means of batting away the complaint without really investigating it in detail. Conveniently, the riders manual does detail cleaning regimes & the products that are acceptable so, when complaining, it is always important to make it clear precisely what has been used, if anything.

Looking forward, the dissatisfied rider needs to see how the matter was referred to BMW though; was the case supportive or not - he/she would be best advised to escalate the complaint by having a meaningful discussion with the dealer principal, in line with the procedures detailed on the BMW Motorrad UK website.

That is my experience as well.
If corrosion is there, it is for a reason, the corrosion does not start out of the blue.

I once had a car where the wheel fasteners where covered with plastic caps for the sake of looking better. On this particular car the caps did not have a tight fit to the nut, so whenever the car was washed, hosing the wheels would make the plastic caps pop off.
I brought the case up with my dealer, who promptly came up with a new set of caps. The new caps where a tight fir, and stayed that way for my entire owner ship.

I had a word with my dealer a while after the new caps where installed, and we where wondering why the first set where soo loose. They all where loose, no exception. I used the same type of soap and solvents as always, and none of these affected the plastic caps.
We ended up our friendly debate concluding that the car most likely had been exposed to some sort of solvents during pre sale preparation, as that would be the only time the car would be exposed for solvents and cleaning prior to my ownership.

Could the case of corrosion be the same type of issue? We are talking about an almost brand new bike, and the corrosion does not make sense. Something must have been done to the bike for the corrosion to begin, and if the owner is dead sure that none of his doing has caused the issue, then dealer/service staff is the only plausible alternative.

I acf50 all metal parts, nuts and bolts on day 1, on delivery. As well as all naked machined parts on the engine block (the ones that remain unpainted), and all painted bits such as final drive and engine. I ride in all weathers (but only 5k miles per year), I repeat acf50 2-3 times per year after a major jet wash. Never had any corrosion or bubbling issues in over 10 examples from 02 model year onwards to today. Except the one example (documented here previously), an 05 hex GS, that I bought privately with 1700miles m-basically new- which apart from being yellow was an absolute lemon of a bike. Corrosion was the least of its problems. In 15k miles it consumed every possible non consumable part.

Valid points Squibb, will pass on and try and get pics.

The bike could have been washed at a supermarket jet wash and we know they cause corrosion...
