Tail Bag / Luggage / Passenger Back rest?

I have a Ducati ST and it has a GIVI box on the back ( my step daughter calls it a BBQ'er) for storage and also for a passenger back rest. My fiance really loves riding the ST because of the back support. I would like to get one for the 86 VF 500s p we can ride it together as well. Anyone have one? or any brand for that matter?

 

All the luggage systems for these older bikes are long gone. Ocassionally a used setup will appear on ebay, but they get pretty expensive. The only real way to get what you want is to adapt a newer case or bag set to your bike by building or modding the steel mounting brackets.

 

Thanks thats the info I Was looking for
