Thanks to Craig NOS in the comments and a link to a French message board.
- Racer made by Sebastien in the south of France (Var) then sold. More details in the forum link. I am looking for more information.Craig NOS from Ze Craignos Monstercycles.blog
And one more bonus pic lifted from over there: Stunner!
I really want to know more bout this bike but I found it in a really obscure place. Can anyone enlighten me a bit on what must be a fairly well known ride in BMW circles?
