For anyone interested I have a Corbin seat built for a 2009 R/S. It is a two piece with a spider web design, fuel door, & locking rear seat. I think they are still the same seat for today's Spyders.
Orig. cost was around $650 from Corbin. I put about 20 miles on it before I sold the Spyder, & they didn't want to buy the seat.
I would like to get $500 & I'll ship in the U.S.
I'm not home right now, but will post pix in a few days. If interested PM me.
Ride Safe !
