To answer your questions:
The seat was done by Rick Mayer:
http://www.rickmayercycle.com/I sent him the original stock seat, and he worked his magic on the original pan. Since the pan was unchanged, I didn't have to change around the mounting brackets. Because of the leather "throw over" part of the saddlebags, I did have to trim the rear rubber pieces to compensate. There was still a bit of a wrestling match to get all three screws started, but it fits great.
I sent the seat to Rick on Jan 15. I remember the date because he extended the winter special that the web site said had to arrive by that date. I just got it back Wednesday May 6. Rick does all the custom work himself -- it's a masterpiece. Being that he extended the special, I sprung for the leather.
Since I had already tried the cheaper upgrade of the pillow top gel seat from Suzuki, I managed OK! (I have a friend with a Savage -- if she doesn't buy that seat from me, it will be offered to you guys.)
(If you only see a Sportster, "slide" the picture over. There's a Savage in there, too!)
Why Rick Mayer? I owned BMW's for about 20 years and have seen his seats on a lot of long distance riders' bikes. I liked the looks and the reputation.
He is just outside of Redding, California. If that's within riding or trailering range for you, you can schedule a ride-in appointment. That will let you break in the new seat on some incredible riding!
As for the luggage rack, that's a standard Suzuki rack. You need the sissy bar to mount it. I got mine from Oneida Suzuki
http://www.oneidasuzuki.com/store/home.phpThey usually discount Suzuki's list price and sometimes even put them on sale!
And I wasn't real pleased with the way the sissybar pad looked. Once it was off, there are the two holes for the screws. I stuck the Suzuki emblem back on the back side, and put a "dash plaque" from the BMW Owners of Japan on the front side.
Thanks for all the positive feedback!
