Ever since I have my Vit 701 I wondered if I could reduce the vibrations in the bars. They’re not really bad, but they are there. My bike came with those little bar end mirros, so not much bar end weight.
I didn’t want to make the bars any wider than they already are (filtering through traffic), yet I did want to add some extra mass to the bar ends. Then I found weights from Sato racing that go inside the bars! Very happy with them.
