FZS1000 Black engines

[unfazed]

I have been looking at a few FZS1000 online and not sure if this is normal or not. Some of the ones with black engine cases appear to have silver or grey cylinders. Is this right or should i be wary?

It was never available with black casing silver engine onl all black or all silver.
Most likely the owner replaced them due to accident damage or painted them black due to the silver paint peeling as it was an issue with the earlier silver engines.
Just ask when buying, but if the machine is in good condition and no obvious accident damage I would not let it put you off
