Since this issue recently showed up, I would suspect that your front wheel is out of balance. Are any of the wheel weights missing?Hi guys,
Im having a similar problem of pretty hefty vibration when going highway speeds which has only seem to have come on recently (bike is on 4000 miles).
Definitely nothing to do with my grip since it has happened after reading twist of the wrist which led me to completely reduce my grip strength.
I bought my bike used and it doesn't have bar ends which seems like it might be some of the problem (although doesn't explain the sudden onset).
Do you think weighted bar ends would do the trick and if so does anyone know the size I can't seem to find it anywhere? Was gonna go with 7/8
Good suggestion, thanks. Just checked and there's one on each wheel, which is correct right?Since this issue recently showed up, I would suspect that your front wheel is out of balance. Are any of the wheel weights missing?
Bar end weights do make a difference in the amount of felt vibration.
Yeah I noticed there was an internal bar weight when I looked up replacing the end weights. I think when I'm looking into the bar all I see is the end of number 5, the thing thats like a semi circle. So I guess I'm missing 4 and 3. Im definitely gonna just replace the bar ends when I can get to the dealer. I was pretty unsuccessful in trying to work out which non OEM bar ends would fit the bike…Something to possibly consider concerning handlebar vibration.
Along with the bar end weight there is a larger internal bar weight
also. It is located into position with tabbed ring #3 and two rubber
star shaped cushions #4 then secured with the screw that goes
thru the end weight and into the end of the internal weight.
You said your bike has no end weights which would indicate that
the internal weight is not rigidly secured. Possibly over time the
internal weight has loosened and has started to vibrate.
Not saying that is what is happening but maybe it is something
to think about.
See the pic for the assembly illustration.
My extra space is on the clutch side, perfect… Throttle one looks about right but the other one is at least twice that distance, maybe half a cm. I can add a picture if thats helpfulI wasn't thinking when you said there was a gap difference
at the bar ends. There is a larger gap on the throttle side.
I think it a safety thing so nothing would get in and bind
I took a couple of pics of my bar end/grip gap to compare
to yours. If your gap differences are similar then that is ok.
I think the gap is variable, and trivial, providing there is one on the throttle side. I added Helibars about a month ago. Part of the changeover is removing the bar weights from the OEM bars and reinstalling them in the Helibars. The gaps changed from before to after. There is a little play in the mounting mechanism of the weight inside the bar. Basically, a rectangular pin has to fit in a round hole. There is some slop of a few millimeters.I wasn't thinking when you said there was a gap difference at the bar ends. There is a larger gap on the throttle side.

I am a little confused as to whom your post is directed to.I think the gap is variable, and trivial, providing there is one on the throttle side. I added Helibars about a month ago.

Before the change, I had zero (0), zed, nada, gap on the throttle. The bar end would rotate when I twisted the grip. This is not good. My CBR had less than 600 miles on it at the time, so I assume it came that way from the factory! I now have about a 2 mm gap on each side.
Yeah I've been looking at the ends of every bike I come across and mine is definitely the only one with such big gap. Im thinking that the internal weight is not screwed in entirely. Is there a way of adjusting it without taking the bar apart?I am a little confused as to whom your post is directed to.
If it was to me, I have no problem with my bar end gaps.
My pics were only to show Clarko21 what acceptable gaps
might look like.
Take a look at Clarko21's picture and (seriously) tell me that
it looks ok. That is a huge gap and something should be done
Perhaps a little assistance for him would more fitting and I
don't think switching to a complete set of aftermarket bars
is in order.
Thanks very much for your detailed reply. I have just checked and it looks as if the flange is correctly clipped onto the weight, however the internal weight to me looks like it is extending too far out. As you can see the flange is directly in line with the end of the grip, rather than being slightly inside the grip. The last photo shows mw holding the weight in alignment with the ring snap, showing that in the correct position its still jutting out of the bar. I will definitely run by the dealers tomorrow though.Hey Clarko21 I'm back again.
Lets go thru all the bar weight parts, where they are
and what they do. There are only 6 parts plus the
handle bar grip itself. I don't want to bore you but lets
On the handle bar there 2 holes 1 locates the position of
the lever control housing and the one near the end locates
the inner bar weight assembly. Neither one is adjustable
other than a little wiggle room.
The inner bar weight has two rubber (star shaped) cushion
rings that center the bar weight within the handle bar and
helps absorb the vibration. The last inner part is the snap ring
that hooks on the inner weight shaft, has a tab that snaps into
the hole in the handle bar, and 2 flanges that butt against the
end of the handle bar. The double pic shows the snap ring itself
and the red arrows the basic location where the handlebar hole
is and one of the flange tabs that contacts the end of the handle
Now (hopefully) comes the easy part.
Take your bar end weight off and compare the pic with the red
arrows to see if everything looks the same (flange against bar
end) and the handle bar grip extending past the (bar end).
Put the bar end weight in and make sure the flats align. It
could be as simple as that (the grip was installed too far in
or the flats were not seated together).
When screwing the end weight on you must make sure the flats
are aligned and hold the end weight as tight as you can because
there is nothing to prevent the inner weight from turning.
If this doesn't do it, I think you should run it by the dealership
and let them take a look.
