The most "common" option that isn't too expensive is the Givi Wingrack (1 or 2) + a FZS600 specific fitting kit. Plenty of Wingracks to be found on ebay but I put "common" in inverted commas because the fitting kit is harder to come by.
Keep a look out and you will likely find one before too long though.
