While on a ride yesterday my riding buddy decided to open his bike up on a long stretch of desert highway. I decided to follow, it did feel good. My 2005 Wing keeps up well with my friends Concours 14. If we were on a track, not the street, I'm sure I would be a spectator. Anyhow, I got up to an indicated 120mph and a vibration started, which made me back off. It seemed to be in the chassis, not the handlebars or fairing. It was smooth right up to 110mph. It's a 2005, 68K miles, new rear drive unit and propeller shaft, recent Dunlop E4 tires, Centramatic balancers, Traxxion suspension all around. The easy answer is to not go that fast. I do wonder and worry that what ever caused the vibration is a fault, and will get worse, so I'm curious as to what caused it. Why is it OK at 110 and not 120? Do the Centramatic balancers not like high speeds? Front wheel bearings or steering head bearings at fault? Is the new propeller shaft not balanced well? So I'm wondering if anyone has had a similar experience and any ideas as to the cause of this. For the record, at 120mph, it felt like it still had a bit left .

Chopin, please elaborate. Is the GoldWing not safe at speed? Is there an upper limit to it's capabilities? I'm not really afraid to take a bike up to those speeds for moments at a time. If Honda designed that bike not to exceed some lower speed, they should have put in a governor. Surely I'm not the first to take a Wing up to those speeds. It's a much better built bike than some I've had up to those speeds in my past, thinking of a few British built vertical twins I rode in my youth.

No the bike is fine at that speed but Chopin isn't. I think his limit is about 70 and that is being generous .
The bike will get up to around 127 mph , measured with my Zumo 590, before it runs out of power. It was rock solid at that speed. I know Dyna beads upper spec is 105 mph. So my guess is the Centramatic balancers.

Mine has been to 115. Not sure if that's the bike limit, but it was my limit on the road I was on.

Now, Lee going over 55 would not shock me, but him beating anyone to an exit would.

Ahh, good to see Jinx had a top speed run. I imagine, what with the built in speedo error, I was actually up to about 105-110. Interesting thing about the Dyna beads, topping out at 105. I wonder why. The Centramatics had no warnings about top speed, but in reality, it seemed like the tires/wheels became unbalanced, it was not a violent shake, just a vibration. If that is what is was, I'll quit worrying. And, for what it's worth, quit doing that high a speed. Anyone else have input about the Centramatics?

at those speeds all you need to do is hita rock or a pot hole, and it's good by. I know a guy that has a Kawasaki ZX 1400, same motor as in the Concours but not tuned down. He hits 180 on the street, he's nuts and awful lucky. (I had an 09 Concours 1400) never took it that fast.

I've always been told over 70 you hit something you're dead anyway, might as well let it stretch its legs! I don't think I've ever been to a hundred and twenty, but definitely a hundred hundred and ten no quiver on the atpck F6B

At that speed it could have been wind sheer on any of the Tupperware or windshield. Something as minor as having the windshield vent open could cause a vibration. I’m betting it was the centamatics also but I’m surprised you were able to isolate the vibration to the wheels and frame. I’ve been at 100 with my 2015 and that’s fast enough for me.

The vibration was minor, but enough to make me back off at that speed. It was definitely in the pegs and seat, not the bars or between my legs. I never took the time to check out my mirrors. As I said, at that speed I was taking no chances. I will say that this GoldWing continues to amaze me, performance beyond what I expect.

I have Centramatics on my Wing ('09) and have seen an observed 220 kph (136mph) on the clock, no worries. Don't really know what your issue might be, but a large fairing equipped m/c book says never exceed 80 mph...if you believe that. To make a point at any speed a brick wall is deadly.

Is that 136 mph with a corrected speedo or thru some other method ? Just curious .

I sent off a polite enquiry to Centramatic as to a higher speed limit to the balancer's effectiveness. A Jerry Robertson replied quite quickly, and said that the Centramatics do not have an upper limit, that I have a list of other culprits to look at, including tire wear and roundness, rim roundness, steering head bearings, wheel bearings, front fork set up and front axle indexing. Maybe a couple of other things as well, so I'm gonna be a busy guy. I do think that with the mileage on my bike, front wheel bearings and steering head bearings may be on the menu for this winter.

There are old riders and bold riders but not many old bold riders. It's going to catch up with him sooner or later and I hope no one gets killed.

There was a year that the frame had a bad weld or had to be re-welded. Does your Wing fall into this category?

Mine is an 05, I think those have the improved heavier frame, no recalls. One other thing Mr. Robertson from Centramatic asked is, did I have needle head set bearings. What is the story on steering head bearings. Is a needle bearing set some upgrade that is a good thing?

I am one of the old bold riders and I think there are a lot more around than you think.

One thing I will say is when ever you get on a motorcycle you better be telling yourself that it may be the last time. Lost too many friends that have lost their lives not because of what they did but because of what someone else did.

I agree with what you're saying. I think doing 180 on city streets is more than stupid. I'm sure we all open our bikes up, I do from time to time hitting 100 &. 110 but not on city streets or where there is traffic or could be traffic.

I see a lot of 'crotch rockets' going like a bat out of hell in traffic areas and I've seen a couple wipe out too. A lot of road rash and one with an open skull. Riding with shorts, flip flops and tank tops.

I too am old and from time to time a bit bold but I can say I'm not stupid like a lot that I see around me in the summer. When the temps drop into the 50's they are no where to be seen.

Wait What ?? is this the same Steve that gave me grief for going a little fast on a nice Sunday morning ride coming back from the Meet & Greet in Pa.?
I guess that get out of jail free card you carry might come in handy someday:wink2:

I went 100 in a 70 MPH zone which is exceeding the posted speed by 42%.

You went 60 in a 35 MPH zone with is exceeding the speed limit by 140%. Hmmmm, I think you were worse!

This was my last venture over a 100 on my '08 with beads in my tires. The ride was very smooth, but I also had a tornado chasing my ass so I may not have noticed anything unusual. :surprise: 117 mph is the fastest I've had my Red '08 and it was smooth as a babies butt. I also run darkside on the rear so that may have been a factor. >:)

FYI, the fastest I had my wing up to was 187 KPH, which converts to 116 MPH. In doing so, it ran very smooth at that speed. The thing that makes me nervous at these speeds is :policeman: I also have Centramatics on my bike.
