Bell BR1/Star Infusion Vent Top Plate - Matte Black H778C31L Three shell sizes for optimumThanks to the versatility of the BR. 1 and Star Infusion Helmets, racers no longer have to choose between a side forced air or top forced air model. By installing either the side forced air or top forced air kit, the BR. 1 and Star Infustion become a full ventilation forced air helmet. By using the kit system, racers can easily switch the BR. 1 to the appropriate configuration for their type of racing.
