Been reading this thread with great interest! I'm sadly not a CVO Owner myself (though if they produce the SEEG3 based on an Ultra, I will be!) - I have a 100th FLHTCUI, and a '01 Sporty, both since new. I've ridden a lot of Glides, and there sure is a LITTLE bit of a wobble problem. My own current one was fine when new, but after I replaced the rear tyre (with a Continental - the standard Dunlops are not good in our climate!!!!) I got the high speed "wallowing" wobble on sweeping bends. Not nice, but liveable with. Friends have the same experience. I'd been putting it down to the Continental on the back, with the Dunlop still on the front (I know, I know!) and thought that it might be resolved once the front Dunlop wore out, and I could replace it with a Continental too. Certainly tyre pressure or suspension pressure variations don't make a lot of difference to it.
But recently I got the chance to ride a brand new SEEG2 (600 miles when I rode it) that a friend bought. Man does it go! :-) I really want that torque and power! Two problems with it though 1) FAR too low! Tight curves at any speed are a reall no-no - dig big furrows in the tar with the jiffy stand and to the extent that I could not get it on a big enough lean for our twisty little roads. That one would be easy enough (though expensive!) to cure though. 2) Wobble. JEEZ DOES THAT BIKE WOBBLE! As I say, I've ridden a fair few Glides, and most, including my own, have the "wallowing" wobble, especially on long curves. But this SEEG
