There have been threads upon threads on this topic. No one KNOWS exactly what causes it. I think the whole design is a little susceptible from multiple things being the root cause. I know I have "felt it" with brand new tires. Seated the front axle per the shop manual. Some blame worn front tire. Some blame rear tire. Some blame "bad" new tire. For those that seem to thing it is even an issue at all, seem to instal tapered stem bearings to stop it. I can tell you that I have felt the wobble when I let go of handle bars on decelerate just to see if I could feel what others want to complain about. If I didn't completely let go, would never know it was there. If you install tapered bearings hope you enjoy those. I did only because my new Traxxion system came with them installed. I hated them when torqued as tight as most recommend. If the whole thing really bothers you.... either don't buy a Wing or install tapered bearings if you ever feel it as a significant problem. Lots and lots of threads on this. Almost like oil threads.
I think the OP is concerned that the F6B will do the tank-slapper decel wobble that the Goldwing has been well known for. For my 2008 ABS Goldwing the tank-slapper was very real during decel. I tried letting go a few times and the wobble started slow but quickly became real bad. As I'm aware, there was never a 100% fix for it as no one seemed to know the cause. Plenty of speculation but nothing definitive. I can't see why the F6B would be any different as it's pretty much the same bike minus some Tupperware.
So I dropped the bike into the local Bike tyre place to get the front wheel balanced?
Apparently it wasn't too far out but they did tell me that the steering head bearings will need replacing soon (34000 kilometers) 20000 miles?
Seems their a big culprit when it comes to front end wobble?
Seems way to early to think about replacing steering head bearings?
Well i started out with nothing and I still got a whole lot left
I replaced mine at 95,000 and only because the Traxxion tree came with tapered bearings installed. Mines a 2012. Had the slight decel "wobble" off and on from day one. Sometimes go away for a little while with new tires and sometimes it wouldn't. I would not have installed the tapered bearings at all if the full Traxxion front end didn't come with bearings pre installed. Personally, I would never install tapered stem bearings for the sake of trying to "eliminate" the slight "wobble". Now if one had a real "tank slapper" I suppose I would be concerned. Most I have heard about on this forum were not severe at all, but not good if you were in the habit of slowing down while texting on your phone or sitting with your arms crossed, etc. Very slight pressure with only one hand and mine was always un noticeable. Others experience may vary.
