Hello everyone, Boo here.
When you check behind you in your mirrors while riding, have you ever found that vibration blurs everything and makes it hard to see?
In fact, Honda and Suzuki both sell genuine rubber mounts that reduce motorcycle mirror vibration.
Conclusion: genuine rubber mounts get rid of the fine buzzing
- Fit a genuine Honda or Suzuki rubber mount between the mirror and the handlebar
- Fine vibration (a buzz) no longer reaches the mirror
- Large movements remain, but they become slow swings, so it is easier to see
- It does not get rid of vibration completely

The bikes I fitted them to, and how they worked
I fitted rubber mounts to my XR250 and G650GS. Now I use one only on the XR250 (I no longer have the G650GS).
This is how the mirror movement changed before and after fitting them:
- Without the rubber mount: fine vibration (a buzzing feel) reaches the mirror, and the mirror shakes rapidly
- With the rubber mount: fine vibration does not reach the mirror, but larger vibration does, so the mirror sways slowly (a slow wobble)
To put it another way: without the rubber mount, the mirror is like the twigs and leaves of a big tree thrashing in a strong wind. With the rubber mount, it is like the trunk of the tree bending slowly in the wind.
I couldn't get rid of the vibration completely, but just losing the fine buzz makes it much easier to see behind you. I haven't tried other fixes, such as adding washers or rubber.
If mirror vibration bothers you, I think it is worth a try.
