Its probably because the first time you would have used the allan key it either would have broke or just chewed the allan key head. Ive used one or 2 different took kits with bikes and all the keys, spanners ever thing are cheap crap. I think they make it like that so you damage something so have to go back to them to replace the parts you wrecked with there crappy tool kit.

I always carry a torch once had a ZZR250 which the battery once slide from the holder to short it self on the mod'ed carbs. I could see i thing pitch black and only had the torch for a friends until i notice what the probelm was, then it was full speed home to charge the battery again.
