Front engine casings on the LC R1200 RT/GS are known for the same. I know some people who have had success in getting it resolved in warranty but there has also been a blood bike group who had an entire fleet of RT’s with the same issue rejected under warranty. It’s a poor show for what is supposed to be the epitome of a durable motorcycle.
The bad, ignore how filthy the bike is, is this paint flaking a fault that would be covered under warranty or how could it have been caused?.
I make a point of giving the bike a rinse after being on salted roads. It also gets a few ACF50 treatments throughout winter.
