Yes mine did the same and honda replaced it under 45 day cosmetic warrenty. The new one has not had the sasme issue. If your 45 day cosmetic warrenty hss run out then you can try some metal polish and coat it with a protective film of some kind. May I ask do you have the manual or automatic? I have the manual with 1600 miles and hear a whine at 50 mph when i let off the throttle. I dont know if it was always there or if it just started. I would like to know if you have the same issue. One more thing im not liking is when i washed it water got behind the screen. It dryed out but you think they would mske yhast air tight. Other then that im loving the bike and wouldnt trade it for anything. Ive had lots of compliments on it too.
@SharbshooterB I have the same issue with my 2018 Adventure Sports. I had the guys at the dealership take a look and looks like they buffed it out. I also applied T9 Boeshield when I got it back from the dealer and hopefully it works. Didn't know about the 45 day cosmetic warranty and will keep an eye on it.
