hey guys, first time poster here.

I have an 02 954rr that I've been riding for one season now. I just decided to replace the grips and in doing so realized that I am missing my vibration dampener insert on my throttle side handlebar. I am talking about the factory weight that is about 6" long that slides inside the handlebar tube (along with the bushings, clip etc -- all missing). The plastic slider on the end was just held in with the original allen bolt, and then a nut and some rubber and metal washers, with no weight inside the bar.

On the clutch side, the whole assembly was intact, and i did manage to remove it, but boogered up some of the pieces in the process.

My question is I see a wide array of bar end weights all over amazon and ebay but I'm unclear if these are designed to absorb vibration - and if so is there a model that can be used without the factory weight inserted into the bar. It does look like i can rebuild my factory vibration dampeners through the OEM catalog or can I use one of these aftermarket bar end weights with similar results?

This is kind of ironic because I have recently noticed a fair amount of vibration in my arms while riding. So I'm looking for some exeperienced advice on what you guys would do because I want it to work. Ditch the factory weights for some aftermarket weighted bar ends, or rebuild the factory weights, or something else?

Hello rOob. :welcome:

We need a proper m/c chassis engineer for the full facts and data behind this, however .......

In theory, if you want to keep vibration & therefore tingles down (to the levels of the original design) you need to maintain the same Bar End Mass and the same (effective) Isolation Rubber Stiffness & Damping.

So, by example, replacing steel bar ends, with aluminium bar ends of the same size and therefore 1/3rd of the mass, would not give the same vibration damping effect ......

I'm not keen on losing the blood flow &/or feeling in my fingers, but I have changed my Bar Ends for entirely cosmetic reasons. The ones that I use are Stainless Steel (with plastic outer end), roughly the same mass as OE, and bolt straight into the original inserts, using the OE rubbers.

Not sure how long it would take the rubber isolation to degrade changing stiffness/damping, but they are not expensive.

I have these on the XX and the RR-P:

I have fitted Grip Puppies to a couple of bikes to counter vibration.

https://motorcycleparts-uk.co.uk/pr...2H5dH3Rn1AEpz5OEVx7v-RSV3O7K2P7hoCYtMQAvD_BwE

Less vibration, but it makes the grips a larger circumference so takes a bit of getting used to. Perhaps I could also benefit from better dampeners. Shall do some research!
Research! Good Job, Nigel. :thumb:

My 20p bet would be that the bar end dampers are for vibration from (multi-cylinder, high-er rpm) engine harmonics.

Your Puppies will also isolate your hands from road surface roughness ......

Thanks for the insight. Ended up ordering all the missing pieces off an OEM parts website.

One question. The OEM bar sliders, the actual bar ends, are those weighted as well or are they just plastic?

They are aluminium

Hello rOob, Did you mean the Honda OE bar ends Item #8 on the exploded view above?

If so, they are steel, black painted .......

With the greatest respect, I try to avoid R & G as much as possible. I strongly object to their manner of plastering their logo so prominently on many of their products. Fortunately, the rad guards and tail tidies are 'discretely' marked.:wink

Just sayin', by the way.
Hahahaha! I completely empathise Nigel! :grin:thumb:

The other day I had a partial Basil Fawlty moment, as in about to beat an inanimate object with a tree branch ......

I ordered some R&G Radiator Guard rectangular sheet. The advert photo had a large R&G logo on it, but 1/ I looked carefully, and the logo was clearly also crossing the holes in the mesh, so was just a watermark on the photo, and 2/ who would want to cut the sheet and have a part of the R&G logo on their radiator guard, madness, right? Nope. It turned up with the logo?!? :idunno: I was about to go into the garden to get a branch when I realised that it was only on one side, so can be hidden on the inside of the fairing. But, I will know that it is there ...... :mad: ......

I only get the Bar End sliders because they are, as you say, discreetly marked.

P.S. "With the greatest of respect" :rolleyes::wink:grin

The OEM bar ends on my RR-P are Aluminium, I’ve just checked with a magnet.
I sit corrected, until proven innocent, Gunk. :wink

I’m going to check the OE bar ends that I have up in the loft.

When I say OE, I mean originally on my bikes - none of which I have owned from new. :angel

P.S. Aluminium bar ends don’t feel like they have enough mass to work the rubbers and damp out the tingles. :nerd Just saying.

Hello rOob. Have you had a delivery of your parts yet? If so, what are the bar ends made of, please?

I know the bar ends on my 87 600f were steel, but have never owned an SC28 with OEM bars so I don't know. I think I agree that aluminum bar ends are like tits on a bull (useless).

I've just done some sums :nerd:

- I weighed the "OE" bar ends, and they are 125-ish grams

- Then I filled my bath to the brim, dropped a bar end in and collected all of the spilled water and measured the volume
(no, not really, I measured the diameters and lengths and calculated the volume, but that is very dull).

- The density is waaaaaay above Aluminium. But, interestingly not quite steel.

Using the old adage, "If you (live in the UK and) hear the sound of hooves, think horse, not zebra", my conclusion is that the bar ends are quite clearly made from Unobtainium. :wink

Maybe just me.... but I don't mind a little (and to me it is a little) extra vibration in exchange for weight... I'll take my lack of "vibration dampening" for shaving a pound or so of weight1

Not just you RRDemon. When I had my 929 - lovely bike :thumb::thumb::thumb: - I had Harris clip-ons (aluminium tube with a plastic end cap) and cannot say that I noticed.

Having said that, I was only riding for about 20 minutes at a time ........ and the 'road' surface was very smooth. :devil
