Bell’s rear spoilers are designed to help improve the overall aerodynamic performance of the helmet. Bell spoilers can be custom painted, but Bell recommends using the adhesive to attach the spoiler to the helmet. The HP7 F1 spoiler is designed specifically for the HP7 and can be used on models based on this design including the RS7SC LTWT, RS7SC LTWT, RS7 Carbon, RS7 Pro, RS7K LTWT, RS7K, GP3 Carbon, GP3 Sport, KC7-CMR Carbon, and KC7-CMR. The spoiler is available in clear and attaches with aggressive double-sided adhesive. Available in Small (1.5 inches), Medium (1.75 inches), and Large (2 inches).
