My first FJR was on 08. Hope you like it. Heat manageability, +1 for FJR. Gas capacity, +1 for ST. Either one outlasts my bladder.
And the FJR does not have the overengineered Secondary Master Cylinder POS. Still wondering why Honda ever came up with that great idea. Affected ST's and...
I find the bike very stable on this type of jack. Used it on my former 2018 Goldwing and very stable there also. You could attach straps to keep it from tipping but I have never felt the need to do that.
Also in your area is the Corbin factory. You can make an appointment and ride in for the build. The one butt on their seat is it can only be used in the low position of the bike so if you are a tall guy then probably not.
I ran it the other way from Alpine south to Morenci. Have made this run many times over the years. They have an old 666 sign at the Bear Wallow Cafe and won't part with it. Not yet anyway. I keep trying.
Being on the ST Owners forum I see the FJR being around for quite some time even if Yamaha ceases production. Someone will post a RTE on that board and maybe one or two ST's will show with all others being Yamaha's, BMW's, and various other brands. Of course the ST has been gone since 2012ish...
