The BR.1 features a lightweight composite shell, leading-edge styling and a large eyeport. The standard BR.1 is sold in the standard helmet configuration that utilizes rear facing vents and a venturi ventilation system to exchange air inside the helmet. As air flows over the helmet, the venturi effect increases cooling inside the helmet and prevents shield fogging by creating a vacuum to pull airflow thought the helmet. The helmet's rear facing chin bar vents and top vent provide ventilation while preventing dirt and dust from entering the helmet.
Thanks to the versatility of the BR.1, racers no longer have to choose between a side forced air or top forced air model. By installing either the side (left) forced air or top forced air kit (kits sold separately), the BR.1 becomes 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. The BR.1 incorporates Bell's air chamber technology to increase pressure and accelerate airflow (when used with an external forced air system) to maximize airflow for improved ventilation and comfort. Bell's 2011 forced air helmet features the new Quick Lock forced air nozzle that locks the forced air connector in place yet allows for easy release. The smaller nozzle design helps accelerate airflow into the helmet. The Quick Lock nozzle can be used with traditional 1 diameter forced air hoses by using the following forced air adaptor that connects the hose with the Bell Quick Lock nozzle.
The BR.1 also features Bell's redesigned face piece with recessed areas that allow for seamless radio integration and easy installation. Racers can also customize the fit of the BR.1 by using Bells Cheek Pad Inserts in 5mm, 10mm, 15mm and 20mm sizes to tighten the fit in the cheek area. The helmet is available in White and Rubberized Matte Black finish the rubberized surface is more resistant to finger prints and smudges than traditional flat finishes. The BR.1 is pre-drilled for use with head and neck restraint devices.
