Motor-Runner's Helmet

Motor-Runner's Helmet is a piece of headwear

Gameplay
It grants a +5 bonus to Melee Weapons and a +1 bonus to Perception. It is created with a skull and decorated with keys.

Locations

 * It can be taken from Motor-Runner's corpse after killing him in Vault 3.
 * Alternatively, it is given by Motor-Runner if one decides to tell Hsu that Motor-Runner is "dead."

Bugs

 * Sometimes the helmet will give a +2 Perception and a +10 Melee weapons bonus.
 * Motor-Runner's Helmet will sometimes remain in the Courier's inventory even after the associated quest is completed. It is a quest item: it cannot be dropped, placed into a container, or given to a companion. Simple console commands can remove this item from the Courier's inventory.
 * Killing Motor-Runner without having been assigned to do so will cause you to fail a quest. HOWEVER, you can still give the helmet to Hsu for the quest XP (the helmet won't be removed from your inventory though the option appears to exist to drop it. Clicking the "Drop" button will not drop the helmet, and you will simply get the Quest Item error message).
 * Sometimes, in the add-on Dead Money, when this helmet is in your inventory, the game will crash when you find the 'source' of the signal, and the 'trap' is sprung.
