HI DOUG! How ya doin' buddy? Yea, several former Honda ST owners over here you might recognize. You've undoubtedly ridden with Rayzerman at one or more of the ST Rallies in Ohio, although ironically he has moved on from the FJR. ChucklrST is here too. He just posted up some nice pics from a ride in Colorado. Couple more.
If you get an FJR and want a top box you are going to have to get some support for the box in the back (weak subframe), either a Givi SR357 or a stiffy kit made by forum member geraud.
of course the givi trunks come in all sizes and either rounded or angular. I have the 47 liter angular on mine and am very happy with it.
Like the ST a lot of guys swap out the seats for something else and the windshield, and many seem to put on bar risers. I'm still (2 years 31,000 miles) running stock seat, stock bars, and use a cut down shield (-10") in summer but a Yamaha touring shield (+4") in winter.
If you want to ride mine we could meet someplace in between for a test ride. Let me know. Finding a new ES in stock someplace might be tough.
Should have let you take my FJR for a spin at OH-SToc.
Oh yea you are going to like the 6 speed, the cruise control, the power, the brakes, the loss of weight (although the FJR weight is up high), the slipper clutch, the electronics, how ridiculously easy it is to change the oil and filter etc etc
