【ACTIVE】Inner Weight Review

The effect is immensely Large!

I tried to reduce the vibration and numbness by using a Barrel Style Grip with thicker rubber, but it still did not reduce the fine vibration transmitted from the handlebar when running at higher speeds. I'm still having a hard time with this.
The OEM Handlebar originally seems to have Weight, but I bought a vehicle that had already been changed to an external Handlebar.....................so vibration is not a problem.


I found out that adding a Weight inside the Handlebar may improve the situation. I bought this one with high hopes that it would work.

The effect of Handlebar Weight in the first place?
We looked into the following

Handlebar Weight ‥
Pierced Type and Closed End are available.
The weight is placed inside the handlebar.

The use of a Pierced Type→Handlebar Weight to embed a weight in the handlebar to enable vibration reduction. 。 Type combined with additional Bar end weight.
Bar end weight→Bar end weight is a weight attached to the end of the handlebar. As you can see when you remove it, it is a very heavy and sturdy part. 。 The end of the handlebar has the effect of reducing vibration.

Closed End→Handlebar Weight is placed inside the handlebar to reduce vibration.
In case of SR, it is Closed End. OEMHandlebar has Weight as a vibration countermeasure.

Effect of Handlebar Weight ‥
*Only if replaced with an external Handlebar and added Weight.
○ Reduction of hand numbness due to vibration. Prevention of fatigue.
○It is effective for Mirror blurring.
When the vibration of the Handlebar is reduced, the vibration of the Mirror, which is the peripheral parts of the Handlebar, is also reduced and visibility is much improved→ It is effective because the Mirror was shaking slightly when the speed was increased. This is a phenomenon that tends to occur especially with external mirrors.
*If the shaking of Mirror is not eliminated after weighting, I would recommend replacing it with →OEMMirror. Because it is stronger, stiffer and more complete.
○ Effective for equipment around handlebars.
There is no need to worry about equipment attached to the Handlebar loosening from vibration or falling off. Especially nowadays, there are many riders who attach a Camera such as Go Pro to the Handlebar to take videos.

[Notes] ‥
▲Note the width of the car on the vehicle inspection certificate.
If the grip is a closed end grip and a new bar end weight is installed after cutting the grip, the value will change from the vehicle width on the vehicle inspection certificate.
Specifically, for vehicles over 251cc, the width of the vehicle must not exceed ±20mm. If it exceeds the width, the vehicle will not be inspected.

Type of Motorcycle that is easy to obtain the effect]. ‥

Small Engine Displacement Volume Single Cylinder Cars 。 → higher vibration.
Large-sized single-cylinder of Engine Displacement Volume such as 400cc single-cylinder ☆ 400cc single-cylinder
RPMs are rarely high, characterized by Idling to low RPMs and Large vibration. → Higher vibration.

Single-cylinder engines (Small Type to Medium Type) &arrarr; Since the engine is originally a type with a lot of vibration, it is effective.

Exceptions...
*Older 3- and 4-cylinder models of the same year at high RPM. At higher RPM, the vibration becomes finer and the hand becomes numb because the fine vibration is transmitted to the Handlebar.
However, many of the newer cars are now equipped with Balancer to reduce vibration, so I thought this would only apply to older cars.


good point
◎Idling has reduced vibration and eliminated numbness in the hands after disembarkation. 。

◎Mirror is no longer loose, and visibility is improved because Mirror is not shaky!

◎The vibration around the Handlebar has been reduced so that I can attach the Smartphone Holder without worrying about it falling off. I often use my smartphone as a navigation device.
◎Easy installation and no worries after installation due to high precision.

I don't think there is anything bad about it, it is a PARTS to increase comfort.
For vehicles over 251cc, the handlebar width should be carefully selected to ensure that it is large and sturdy, as they are subject to vehicle inspections.

Motorcycle vibration is pleasant at low speeds, but becomes unpleasant as the speed increases. 。 Various positive effects can be obtained simply by adding weight to the inside of the handlebar, so if you are concerned about vibration, regardless of the type of car, please do not hesitate to contact us.

Rubber wanted one for Φ14

[Trying to install it on a GSX-S1000GT.
I bought it with the peace of mind that it was Size-worthy and plugged it in. "Not all the way in...?"
I removed the RUBBER on the back side as a test and it went in easily.
It seems that the inner diameter is smaller at the back of the handlebar.
Repair Parts for Φ14-Φ17 were purchased separately and the solution was to replace the back side Rubber.

[Feeling of use]
Originally, GSX-S1000GT has almost no Handlebar vibration, so it would be harsh to compare it with OEM, but I feel that the vibration is suppressed to almost OEM by using this product together with Bar End, which weighs about 110g.
If you want to change the Bar End but do not like Heavy weightType because it is too Large, it may be worth a try.

[Unfortunate point]
Repair parts exist for Φ14-Φ17, but not for Φ17-Φ20.
The Bolt for this product is M4, and the RubberSpacer, which is JUST for M4 Bolt, is something for which no substitute can be found, so we would like it to be available.
Well, it's one of the cheaper Parts and if it deteriorates You'll have to buy another one." I guess that's what it means.
(In my case, as mentioned above, I use it together with Φ14-Φ17, so as a result, Rubber's Spare is still there.)

[Others]
To remove it, an M10 bolt (1.25 pitch, length depends on how far back you put it in) is needed separately, but at 10cm long, it costs several hundred yen and is surprisingly hard to find.


[Opinions and requests to Manufacturer
Quantity of rubbers for Φ14-Φ17 for Taper Handlebar from the beginning.:2pc. I think it would have been helpful to have it included with the Set. View detail

Vibration reduction

[How is it used?

Was the one you received as per Image?
just as one imagined
How was your experience with it?
Good, almost as expected
[Points to note]
Must check the length and inside diameter of the handle you are using
How did it compare to other products?

Sometimes it works, sometimes it doesn't.

In the vehicle used this time (GSX1100S KATANA with Pipe HandlebarSpec.), we could not feel much effect.
The vibration disappeared in batches, not quite, "Have you lost some weight?" The effect of this is only about

It may seem simple to eliminate the vibration of the vehicle, but it is definitely difficult to do so.
However, even if it falls over, it will not be scratched and look bad like Bar End, and it is easy to install, so at this price, it is totally possible to try it anyway. View detail

Too long.

Cut a little longer than 3cm for Gixxer (ED13N), and Bolt also purchased 3cm shorter at Home center for mounting.
I am very satisfied with the product itself, it took me a long time to install due to my lack of research. View detail
