All owners have meanwhile got a bulletin telling them they can get themselves in contact with there dealer for a new component; a bit of the slide with component number 13271-0169 of the drive chain to the camshaft. This is causing some problems and need to be replaced.
Furthermore every owner gets a new handbook, as there were some minor errors in the books of the 250 and 450F. How the matter is handled in your own country is not clear to us, but be awake!!
