not sure - i can see the lock washer tabs bent over on yours so not sure what else it needs...
I have since changed mine ( 12mm nut now ) but was looking at the old thread and someone said the front sprocket was worn and it does appear to be so i may as well dort it all now as i am putting an R6 shock in as well so will do it all at once before the MOT
