Right, tried taking the seat unit off again and these Ducati s**t allen key bolts that hold the actual seat have burred off!!
  Tried using hex allen keys,standard,wd40 & pliers. Cant gring it off because its recessed. 
 Any ideas...it's driving me bloody mad now,why cant they just use quality steel rather than this toffee aluminium s**t!
 
  Typically, its the last one to come off too.
