Head corrosion

So not strictly RR related but, I did have one [emoji6] my MY17 XR is showing sign of corrosion on the head/rocker cover the rest of the block looks fine. It's just over a year old and was not ridden through the winter so hasn't seen road salt. Has anyone seen similar? I remember the early first gen having sump corrosion issues, my mate had 3 under warranty. I though it was all sorted though. It kind of looks like white pitting from the rocker cover gasket up.
