Motor-Runner's Helmet

 is a piece of headwear in Fallout: New Vegas.

Characteristics
It grants a +5 bonus to Melee Weapons and a +1 bonus to Perception.

Visually, it differs from the average Fiend battle helmet by the Bighorner horns, it's missing the feathers on the horns, there is a key hanging from the left horn and the symbol on the skull is different.

Locations

 * It can be taken from Motor-Runner's corpse after killing him in Vault 3.
 * Alternatively, it is given to you by Motor-Runner if you decide to tell Hsu that Motor-Runner is "dead."
 * You can also pickpocket it. First reverse pickpocket a headgear with 3 or higher DT, and go to another zone and wait for 3 day. Then return to pickpocket it. Hsu will accept it like you have arrangement with Motor-Runner. You can use it when you can't speak with him (seePage) and want to keep him alive and still complete the mission.

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. Note: Despite initially having a weight of 1 pound listed in it's stats, the helmet has always been weightless. Obsidian eventually corrected the incorrectly listed weight.
 * 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.
