I know nearly nothing about this setup. I acquired it in a "horse trade." I had it fitted to my 2011 the day before I got it sold. It mounted over the triple clamps and under the bars. Needed some sort of riser to make it fit and I didn't care to do it since the bike was sold. I bought a 13 and mounts don't fit and I guess I ride tight stuff so I don't need the dampner. Make an offer, I don't want to high jack your thread with selling this thing so if somebody else wants it pm me instead. Thanks. Was recently rebuilt and I had the paperwork to prove it.
