Eccentric Standard Footpeg w/BH bolt (04-BH1030Z) Buell, Ducati 750-1000SS (99+), ZX6.
These replacement pegs are designed to work with your Woodcraft rearsets. They are sold individually and come with a mounting bolt. These are a good idea to have in your toolbox as spares, as the most common scenario in a crash with Woodcraft rearsets is that the peg gets ground down and the bracket can be re-used.
Not actual peg on photo.
