M8 nut with a wrench size of only 11mm instead of the usual 13mm. Required for closed 8, 9 and 10 inch rims. With some rim types the motage with SW13 is otherwise very cumbersome. Furthermore the standard M8=SW13 is not as old as the vehicles. So here with M8 you often find SW12 and with Piaggio in special cases also SW11. A historically correct restoration can be recognized by these details.
