The HP Star Infusion is the latest helmet added to Bell's HP lineup and is intended for racers who use an external cooling system (available separately) or air duct system in a closed vehicle. The helmet can also be used as a non-ventilated model for open wheel racers to meet the FIA 8860 requirement.

The HP Star Infusion features a high-strength, lightweight carbon autoclave shell, aggressive aero styling and a pro-plus style interior that provides superior comfort. The pro-plus interior delivers a custom interior fit by combining Bell's soft plush-density fit pad system, contoured cheek-grip pad system to reduce movement and integrated collar that is designed to fully support the driver's lower jaw bone area. With the versatility of the HP Star Infusion, professional racers no longer have to choose between a side forced air or top forced air model. Sold in the standard top air configuration, the helmet can be transformed into a side (left) forced air helmet in addition to a top forced air helmet (both the side and top air kits are included). The HP Star Infusion incorporates Bell's ground-breaking 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. In the top forced air configuration, the HP Star Infusion divides the air evenly in vent channels that direct ventilation to the front of the helmet to cool the face and prevent shield fogging and into the air chamber top pad, evenly dispersing airflow to cool the driver around the top of the head. The HP Star Infusion has the new Quick Lock forced air nozzle that locks the forced air connector in place yet allows easy release.
