Is this normal?

I was not as clear as I could have been...

My question is really if the pipes indicate the bike as being abused. I've seen pics of the bronzing as being more uniform, but this one seems to look blotchy and speckled/pitted.

Thanks.

Do the bronzed headers on this 2013 CB1100 look normal for approx 4000 miles?

Thanks! --CB360T
