Sway bar

Has anyone installed a sway bar or steering damper on their bikes. A picture of the install and a manufacturer would be great.
Thanks

I'm wondering about the benefits of having such dampener. I suppose on long highway trips it's easier on the arms to have the front firmer following the straight line? I took my Vmax to 230 km/hr and the KZ1300 to about 160 km/hr, and my '83 GL 1100 to 170 km/hr. All of them very stable, yet easy to turn the handlebar when parking.
