Maybe..... Because I WANT one.. (sorry, pet peeve.. People not answering but instead asking "why".. )
But longer answer.. I set my suspension up as well as I could, but my loads vary wildly. The bike is super light (and I'm only 130 lbs) and at over 70mph (I'm commonly at 80+) the front end can get really light and busy. Especially with the high, gusting winds we tend to have around here and 50 lbs of gear mounted on/behind the pillion.
A steering damper will hurt nothing, and easily clean up some of the busyness I am experiencing at speed. I woods raced (enduro and hare scrambles) for ~30 years and then road raced for almost 20 more and I always had dampers (usually Scotts) on all my bikes. It certainly won't kill me to put some kind of damper on this machine. The issue is fitment.. Just finding a mount that works. I may end up just fabricating one from some aluminum in my little garage shop.
