Hmmm.... not impressed. Only just 2 years old, 7600 miles, one winter use, and this happens.
My last bike was a ZX10R with what appeared to be the same finish - 10 years of use, including more than half of them through winter and still as shiny as the day it came out of the crate.
Is it worth complaining to Kawasaki?
I should add the bike was professionally treated with ACF50 before this winter.
