I have a set of Kosman fully adjustable triple clamps for sale that came off a 2005 fs650c. I know for sure they will work on '05-'08 but probably fit other years. I am the 4th owner, but they were only used by the original owner. The guy who originally owned them used them for roadrace and had them set up at 11mm offset. From what I was told these were $900 new. Asking $250 shipped.
