The M-4 is an aggressively styled, multi-featured, full-ventilation helmet with an extra large eyeport. The M4 can be used in all forms of racing. In addition, the M-4 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.
