The Star Infusion has an ultra lightweight carbon composite shell and aggressive aero styling. The pro-plus interior delivers a custom fit by combining Bell's soft plush density pad system, contoured cheek grip pads, and integrated collar to reduce movement and support the driver's lower jaw bone area.

With the Star Infusion's versatility, professional racers no longer have to choose between a side forced air or top forced air helmet. In the top forced air configuration, the helmet can be transformed into a side (left) forced air helmet (side air kit sold separately). The Star Infusion incorporates Bell's air chamber technology to increase pressure and accelerate airflow (when used with an external forced air system) to improve ventilation and comfort. In the top forced air configuration, the Star Infusion divides the air inflow evenly in vent channels that direct ventilation to the front of the helmet to cool the face and prevent shield fogging. The Star Infusion features the new Quick Lock Nozzle that locks the forced air connector in place yet allows easy release. This smaller nozzle increases airflow into the helmet; it can be used with traditional 1.5" forced air hose by using a forced air adapter that connects the hose toh the Quick Lock Nozzle.
