I spoke to Steve Harris about steering dampers when I was building my Harrier. I been reading about chassis set up and how someone had wrote that a steering damper is just covering up poor chassis design.
When I relayed this to Steve his reply was something along the lines of: “hmmm... frankly ALL motorcycles should have steering dampers. It’s insurance. You hope you’ll never need it a d yiu probably won’t, but if you do, it could save your life”.
