Hello, I have a blue 1992 K75 low seat model with the tank surround. I recently acquired the tank surround, however the bike has a Corbin low seat that doesn't fit with the tank surround. The Corbin has a hole for a backrest. I do have the backrest that could be part of the deal for the correct seat. The Corbin seat is in good condition, but not new. I live in Savannah GA. USA. Thanks for your consideration.
