Nice bike..I have the same one

What colour is the NH, Candy Flair Blue or Cosmo Black?
I'm pretty sure this tank is unique to that model and year. Here is the part number.. I don't see a cross reference to another model.
TANK, FUEL *PB115CU* (CANDY FLAIR BLUE)
175A1-460-840ZA
TANK, FUEL *B100MU* (COSMO BLACK METALLIC)
175A1-460-840ZB
Neither one are available anymore.
