I did a short write-up on my new Corbin seat for my 1979 R100RT. It's on our blog at www.airheadmoto.com
Thanks for the write-up on the Corbin saddle. I'm getting ready to drop the $ for one myself. What model did you get ? I'm thinking about the Canyon model since I ride more "short" rides than "iron butt" type rides. BTW, Im on a 80 R100RT.
I got the dual touring saddle, but if you just do short rides and don't do two-up riding then I'd get the one you're looking at, the canyon model. Now that I have a couple of thousand miles on it the saddle feels much more comfortable, so much so, that I don't give it a thought.
