The M-4 Top Air features aggressive styling and an extra large eyeport for maximum visibility. The M-4 Top Air incorporates a low profile top forced air chamber designed to accelerate airflow around the top of the head to improve comfort and ventilation. In addition, the M-4 Top Air features our new SRV friction shield system. This new system has a slide mechanism that allows the driver to adjust the tension on the shield allowing for multiple opening positions. When properly adjusted and in the locked position, the SRV systems helps reduce the possibility of the shield opening during an impact.
Bell Racing Helmets are pre-drilled specifically for use with HANS Clips and the HANS device. Consult the manufacturer of any other head and neck restraint device for proper use and installation as hardware and mounting locations may be different.
