Honda does not care and their mismatched dampening in the forks and lack of a solid "full box support structure" between the two lower legs to guarantee unison in movement is part of the cause. I have Traxxion matching cartridges in each leg and tapered roller head bearings in my 2010 and that eliminates the issue until the front tire is done with a near slick left side and more tread on the right.

 

OP does not mention the year of the new bike he bought last year. If the OP bought a new bike last year, it could be a 23 or 24 model wing. If so, it would not have cartridges in the forks.

 

Several folks have reported a shimmy or wobble in the speed range you mentioned, especially during deceleration. Honda's answer is don't take your hands off the bars. I've found on a couple of bikes the steering head bearings weren't torqued sufficiently. Basically the front steering was "sloppy".

Not saying that's your issue, just an observation. Jack up the front with the bike on the centerstand, check the looseness/tightness of the front steering.

 

I also recommend to check and probably tighten the steering head bearings. At least it worked on the Harleys I owned and the three Harleys I owned that all were loose. One was scary loose, like 3-4 turns on the nut to tighten.

 

" Head shake is not very common for the 2018+ bikes ...."

Yeah, it's more common on the '18's and above than you know. There's been several on here that have reported it and that's just the ones on this forum. Who knows just how many have it?? Anyway, I've never been a believer of the "loose" steering stem bearings as a cause for this issue. A very, very large percentage of brand new Wings, either 5th or 6th generations don't have the infamous wobble when new. They develop it after a tire is worn or something else causes it. Using the old "tighten the steering head bearings" as a band aid for that situation, is just that, a band aid. I had a wobble in my '08 for quite some time. I had a front tire replaced and that wobble simply disappeared. I could let that bike slow down with no hands on the bars from 50 mph down to the point the bike would almost fall over and not a single wobble.

I was hoodwinked to install the Traxion steering system and all balls when I had the forks down for some seal work. I was also told to torque those "all balls" to 23 ft lbs. That's PHENNOMENALLY TOOOOOOOO MUCH torque on those!!!!!!!!! I've been doing wheel bearing work for decades and those are the same exact bearings as the "all balls" and I've never, EVER, EVER tightened them to that much. When I did torque them in my '08 to that recommended amount, that steering was HORRIBLE!!!!!!!! It wouldn't ever come back to center. I had to force it. So, I backed it way down to 5 lbs. torque. Waaaaaaaaaaay better. But my wobble was still there. That is until I had a new Shinko installed. All better.

So, as to the '18's and above, well, not a clue as there's maybe more than just tires involved.

Sure, it was on Harleys, but I have had the opposite results. Tighten the steering neck bearings and the wobble went away. I had it happen on three of my Harleys and have helped friends with the same on there bikes.

It isn't that the bearings needed more preload, they were simply just loose from the factory. Like I mentioned, on a Harley I had I spun the nut about three turns before the bearings started to get tight, and yes, they can be too tight. On the Harley they had a method of checking the neck bearings called fall away, but it was a ridiculous method of it would take hours to do on a batwing. I would jack up the bike so the front wheel was off the ground and tighten the nut until I noticed a bit of resistance when moving the handlebars bag and forth, then back off the nut about 1/3rd of the turn and snug up the jam nut. Every neck bearing I ever checked on a Harley was loose.

I don't know the procedure on a 2018+ Goldwing, but if I had wobble in the bars and badly cupping tires it would be the first thing I would check and adjust.

 

Was the rear tire replaced along with the front? Quite often shaking in the front originates from a problem with the rear tire. I have experienced this first hand.

 

No...rear not replaced...is wearing beautiful.

 

never had a shake with Bridgestones

First time I had any shake was when Dunlop E4s were getting worn down on the sides, about 70% worn. Shake didn’t happen when they were new. Occurred any speed above 45 but only if I took both of my hands off the handle bars

Now have Michelin’s on- get the shake only during deceleration between 35 and 50 but again, only when I take both hands off the handle bars

in my option, what I experienced is caused by the tire(s) not the bike

Agree with @ssncob
Check the steering nut
Check steering alignment
Both of those considerations can be a factor

 

Same here, I have only experienced mild shaking around 45 mph with no hands on the handlebars, and it never happens with fresh tires. With my hands on the bars there is no sense of shaking or vibration whatsoever. My experience is not limited to deceleration; it would happen for me with the cruise set at 45.

I just swapped my tires last weekend and the shake went away...for the fourth time. The past sets were Bridgestone, and I suspect it will return when these Michelin Road W GTs wear...meh.

 

I noticed a very small amount of this head shake on my 08 so I installed All Ball Bearings and torqued them so I had 3 lbs of pull on the handlebars from lock to lock at the fork tubes with a scale and ended up was around 17 lbs of torque on the head beadings, and it handled great after this.

 

This is a 2023 Model ?
