Just spoke to John @ Revs. He said the spring rate for the fork springs were most likely 8.5kg/mm (would that be in kg/mm or Nm/mm units... not sure). He said on the Fzs600 it usually ranges from 8.0 to 9.5 depending on the weight of the rider and that you're more than welcome to call him to ask about it.
