Before you do anything I would contact Corbin. All that should be needed is to replace the seat pan with one that matches you bike and model. Since the model of your bike and the the one it is intended to fit are so close the seat foam and cover should be very close if not the same.

All that is different is the curve that gos over the console, the standard is much wider at the front than the Classic.

It's worth a phone call.

 

Why not just post it for sale and use the money towards the proper seat ??
