Yes we’re completely serious. These have been tested to 175mph (your results may vary) and will allow you to appear silly whenever you feel like it. The idea of being pulled over and lectured/screamed at by an agitated officer while glumly sitting on your red-hot Blackbird/Hayabusa/ZX12 with droopy bunny ears does admittedly have a sort of humor potential. Large clear suction cups attach these clever accessories to your helmet and allow the ears to flap in the breeze realistically, enhancing the sensation of speed as you roar by unsuspecting normal people. Choose Tiger, Cat, Pig, Bunny, Dog, Angel and Devil. (Helmet not included or available.)
