Want to add some style to your helmet or look like one of those guys in the stunt videos? Here is your chance! These brand new metal helmet spikes are made of highly polished, chrome-plated tempered steel to stand up to harsh outdoor conditions. The spikes have threaded screw holes in the bottom and the matching screws are included in case you want to mount them somewhere else (the screws can be used for other parts of your bike with minor modification, i.e. windshield or fairing fasteners, etc.). This helmet spike kit comes complete with 3" or 4" tall spike and screws!
