I have a loose o ring between the 2 bars behind the front wheel on my givi bars. There is about 1 or 2 mm of play and it rattles really loud at 5,000 rpm. The bolt below the washer with the spacer is as tight as it can go. Any ideas on how to make that o ring secure and is there any safety issues with it being a little loose? I was thinking a shorter spacer or a bigger o ring.

vibration on givi bars 2018 vstrom 650 due to loose o ring

It was a very long time ago I did mine and I think I remember shortening up the tube that the bolt runs through to get things a little tighter.
It is hard to tell from your pic ,but the o rings should sit at the shoulder of the plastic spacer,not be pulled into the tube.
I think the design of that spacer was changed,on my '22 the spacer is more square than yours,again difficult to tell.
Electrical tape round the spacer has helped for some ,as has silocone sealer .
It is weird , a LOT of people have this problem ,so it is a THING , and some don't?
Mine have been on 25,000 miles and never vibrated.......
I have the slider puck on the top bar not the middle, 'cos I fitted highway pegs in that position and have smallbags mounted.This MAY be a difference,but I had the bars on without pegs/bags for a while and no vibes.
The fact yours are vibrating points to movement that may have damaged the o rings so they cannot do their job?....

thanks for all the info. it seems to bee a common problem with the bars. I am gonna unscrew it and take a look at the oring and connector and see if I can fix it. it is only a little loose but annoying to hear.
Gert, on your diagram, I don't have the 2 - #6 rubber o rings. I only have the #3. I assume those #6 are rubber at least. can you tell me if they are in fact rubber? I guess they were not installed when they bars were put on. (i just bought the bike and the givi bars were already on) I could go and get some and try to put them on either side to keep the #3 part from moving. The bar is 25 mm wide so maybe find some that are like 23 mm or something close. If that does not work, I am gonna try your shortening #9 by 2mm like you did. hopefully just adding those rubber $6 o rings will fix it. this is super helpful. so thank you so much.
From what i remember they were a std looking O ring , nothing special, probably synthetic not actual rubber. And not super tight on the spacer, they slid on easily without stretching.
The x2 #6 O-rings were supplied with my GiVi crashbar installation kit. Did you have a look at the pdf link in reply #3 above?
thank you for the info. I am going to try the rubber o rings and see what happens. i think it will work.
I would include at least one tap washer as well, as the O-rings to me are not that durable. See the drawing in reply #6.
