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. If you show it to Colonel Hsu after the mission is over, you earn NCR fame and caps. Alternatively, it is given to you by Motor-Runner if you decide to tell Hsu that Motor-Runner is "dead."

Bugs

 * If you saved in front of Motor-Runner and then asked for his helmet for the first time, reloading your save-game after he gives it to you will sometimes show Motor-Runner without his helmet. This bug can be fixed by reloading again.
 * Even if you ask him for his Motor-Runner's helmet over and over, you will never give him caps.
 * Sometimes the helmet will impart a +2 perception and a +10 Melee weapons.
 * Another bug appears to be if you have more than 1 Motor-Runner's helmet in your inventory. The dialog about Motor-Runner death for Colonel Hsu will not appear. This bug can be fixed using, by dropping all the helmets and let only one to be in your inventory. After finishing the quest, you can take them back.
 * 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: It also weighs 1 pound. (On normal or "non-hardcore" mode even though the helmet's weight is 1 pound, it does not count towards the Courier's weight limit. In other words, the helmet is weightless. Confirmed on 360 and PS3.) Players on the pc can remove using the console command . This will remove the helmet permanently from your inventory.
 * A fix for the helmet can be found here.


 * To fix this on the PC, just open the console and type "SetQuestObject 000F3797 0". (But see below -- you may not want to fix it.)


 * 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).


 * In the new add-on Dead Money, it seems when this helmet is stuck, the game will crash during a beginning quest sequence. When you find the 'source' of the signal, and 'trap' is sprung.


 * On the other hand, if you still have Motor-Runner's helmet in your inventory when you begin Dead Money, you can put it on and enjoy the +5 Melee Weapons and +1 perception it confers -- both quite useful in this particular add-on. (Confirmed)
