I have a buddy that loves his new Stelvio NTX except he's annoyed by handlebar vibes. Throttle bodies are balanced, and bike runs well. But at certain RPM's, handlebars vibrate. I filled my 2009 with lead shot and decreased it to some degree. Are the threaded bar end inserts in the newer NTX's removable for insertion of a Bar snake, or do I need to dribble shot into the threaded hole on the new one like I did to mine years ago?

Anything loose on the bike? Engine mounts things like that? Might want to check that first, make sure everything on the bike is tight and nothing has shift to make contact where it shouldn't. Sometimes even a cable routed poorly or making contact with something will cause bad vibes.

I don't think the bars or bar end weights have changed over the Stelvio model years.

Another thought would be bar end weights of one kind or another. I have used the heavier version of the Throttlemeister on many of my bikes, gaining a quality throttle lock as well as great damping weights.

Some people are more sensitive to bar vibrations than others. I found I am one of those. The only bikes I have ridden that did not buzz were a Gold wing (that one was the 6cyl) and an HD (it shook but no buzz, yes, there is a difference).
There is not a complete solution. Some buzz more than others (like the little BMW F800ST). You can dampen it a little with bar weight. Sometimes the insulated ROX risers work. Usually it just changes where in the RPM band it is the worst.
I have found that gel grips and gel padded gloves do more than the other solutions.
The most difference for me is the throttle lock. That way I can take my hand off the bar, or just rest my hand on the bar instead of gripping it.
FWIW, ask if he has any circulation issues or carpal tunnel. My right hand (and lower arm) will go numb easily due to previous shoulder injuries. Just so happens that the angle of putting my hands on the bars is one of the worst for my shoulder.
-
What tires are on the bike? I would guess the more "off road" the tire tread, the more buzz.

Tell your friend to take a serious pull-bar and/or wrench and go around and tighten the hell out of the attachment points for the tubular engine guard.

By the way, might be a good idea to jerk the gas tank and check the engine mount bolts or lack thereof.
Thread lock and tighten them too.

Some folks claim the stock, internal signal mirrors make the bars shake worse.

Has he got those mirrors with the signal lights included? They tend to shake and feed vibration back into the bars. If so change to the euro signal lights and the plain mirrors. On my 2102 Stelvio, that solved a lot of my vibration challenges.
Also, I am not so sure how well a bar snake would work on a Stelvio because it has tapered bars, so it would be difficult to get the correct diameter bar snake inserted.
Bar Snake advertises a liquid version, but they always seemed to be out of stock. . . . haven't checked their site recently. But it might be useful if available.
And of course there is the option of gel grips!

Huh, I always thought a bar snake was a nasty woman in a tavern.
