Bell’s rear spoilers are designed to help improve the overall aerodynamic performance of the helmet. The HP7 spoiler is designed specifically for the HP7 and can be used on models based on this design including the RS7 Carbon, RS7, RS7 Kart and KC7 CMR. The spoiler is available in clear and attaches with aggressive double sided adhesive. Bell spoilers can be custom painted but Bell recommends using the adhesive to attach the spoiler to the helmet
