Givi Engine Bars - Vibration.
«

Yesterday I fitted the Pile of Poo Givi engine bars. Pile of Poo because they are so distorted by welding getting the middle holes lined up is a nightmare. But they looked good and I can live with a bit of a struggle.
Today I took the bike out and DISASTER. As soon as the rev counter hits 5000 and on to 5200 there is a terrible vibration through the bars and I can even feel it through the pegs. Any gear. Slightly worse on the overrun.
I'm about to rip them off and send them back, it's turned a lovely sweet, new, bike into a chainsaw at those revs. Not acceptable.
Has anyone else had this ?

I have over 18,000 km with my GIVI and there is no vibration.

This is crazy. The only test was to remove the bars, done that, road test, not a hint of vibration now. My sweet X is restored and the bars are going back to the dealer.

You are not the first one having this problem not only on the 500x and not only Givi guards seems it has a lot to do with how they fit and how tight the bolts are might want to take them off and see if maybe a washer spacer or two will make them fit without binding and torque to factory spec's if that don't work than send the pile of poo back

Mine vibrate a bit at 5000 but doesn't bother me since I'm rarely cruising at that rpm. Did you put the two rubber o-rings on the centre part when assembling?

Mine came with the Givi crash bars already fitted and i get no vibration from them either. Maybe the mount points on yours are twisted so when torquing up the fixing bolts they aren't sitting solidly against the engine mount.

Yes I did. And torqued to 60/45 as shown on a page in here. Back in the post right now, hopefully Givi may improve their engineering.

Guess I've been lucky. Aside from some colorful language heard in my neighborhood while installing, they have not imparted any noticeable vibrations throughout the power band. I'd send em back and ask for a replacement if you can. Sounds like you are an expert getting them on and off now so a swap might be worth a try

Great topic, really makes me think! I have the Givi bars and no vibrations (yet). This is really puzzling and we need to get to the bottom of this, there has to be some good reason to what's going on.
Hope everyone keeps posting their ideas and finally something will pop up. (with a good answer maybe it might get back to Italy!)

My long road trip starts in a few days, vibrations have their way of appearing on trips like these...I'll keep you posted if something suspicious occurs...

Trouble is I like things "right" and now I know these bars are being sent out twisted I have no desire to own them. There's a huge satisfaction in offering two parts together that fit perfectly, that's how it should be in the CNC age, for goodness sake they managed it 200 years ago as seen in many ancient steam engines all over the UK. We went to a steam engine rally a few weeks ago, enormous great lumps of cast iron machined to perfection.
I am looking at all the other alternatives, none of which actually look as attractive as the Givi ones, but that's Italians for you, drop dead gorgeous but don't expect too much reliability.
I've had a comment from a Strom owner, he fitted Suzuki bars to his and ended up with terrible vibration, Suzuki altered the design later but by then he had been hit by a car and the bike was a right off, he is riding again, a BMW GS.
