Top quality, made by MB's / MRB. A set of 3 shims to set up your ignition switches.
New ignition switches come with a washer but are usually too big and loose but as the nut is tightened it doesn't tighten to the switch.   
  Headset castings vary in thickness so we've made a set of varying sized shims to make switch fit correctly.
  Comes with one of each 0.5mm, 0.9mm and 1.5mm made in aluminium.
