Yes, I used a set of Honda bars off the V4 1200, and the bar inserts were about 5" long steel slugs. I had to remove them to fit my internal bar heaters, and a right pig they were to get out.The few stock Standard handlebars I’ve dealt with have what appears to be steel in the ends.
I tried scratching at one to see if it was lead but it didn’t mar.
These bars have an opening between the knurls for what I assume is hiding wiring. If that be the case then the metal inserts must be limited in their depth to allow control wiring to enter the hollow of the bars. I’d venture the weights are grip length at most.
If I had to weigh some ends down I’d look into lead anchors.
I think I'd do the test slightly different. Have someone sit on the bike and hold the handlebars while testing. In the real world, that's how the bike will be configured... two hands on the bars. After all, your hands will provide a slight dampening effect. So that's what we need to see, the difference in different weights with hands on the bars.Hey Vic, check this out. DIY vibration testing.
Interesting watch. I’m a bit surprised it didn’t make a more significant difference, however we really don’t know what we were looking at. As he mentioned, perhaps the frequency has bern changed.Hey Vic, check this out. DIY vibration testing.
What a BRILLIANT test!Not too convinced that DIY laser vibration test tels us much of anything. The spread of light on the target looks similar both with & without the weights. And I don't reckon the vibes could be at lower frequencies because he uses similar revs in both cases.
So I think this is one where we'll have to wait for Bosco's feedback when he gets out & about with the weighted bars.

are these the stock handlebar rubber dampers?
Yes they are OEM Yamaha that I bought a couple of years ago.are these the stock handlebar rubber dampers?
a very scientific experiment in my basement laboratory
Moto Guzzi's don't vibrate! They are a 90 v twin with perfect primary balance.My Moto Guzzi comes from factory with bar end weights. I still get a good vibe through the bars at certain engine speeds. I added Grip Puppies last year and they helped but I’d like to make it better. I removed one of the weights tonight and it weighed 240 gms. Trying to load these bars with lead shot will be quite a bit more challenging because the factory has the ends of the bars blocked off with a threaded plug to hold the bar end weights on.
I think I’ll wait until spring to see if the XS weighted bars have improved things before I attack the Moto Guzzi.
I wonder if 240 gms at the tips of the bars will have a better damping effect than my 350 gms along the last 8” of the bars? Time will tell.
