Product information

Description

BELL 4Forty Air MIPS is a full-face helmet designed for mountain biking and aggressive trail use. It combines in-mold construction for lightweight impact resistance with integrated MIPS technology to reduce rotational forces during impacts. The helmet offers extended facial and rear coverage, multiple ventilation ports for airflow, a matte finish, an adjustable visor and internal comfort features intended for demanding on- and off-road riding.

Advantages

The helmet’s in-mold construction delivers impact resistance while keeping overall weight low. Integrated MIPS provides an added layer to manage rotational energy transfer in certain impacts. Built-in ventilation and an adjustable visor contribute to comfort on long or technical rides, and extended coverage around the face and rear of the head increases protection compared with open-face mountain bike helmets.

Suitable for

  • Aggressive trail and enduro mountain biking where additional facial protection is required
  • All-mountain riding that combines climbs and technical descents
  • Riders seeking a balance of protection, ventilation and low weight

When it may not be suitable

This full-face helmet is intended for mountain biking and aggressive trail use; it may be less suitable for casual road cycling, commuting, or situations where a lightweight open-face helmet is preferred for minimal coverage. Riders who require certified downhill-specific features beyond what is listed should verify certification and compatibility for their discipline and local regulations.

Key specifications

  • Construction: In-mold shell designed for impact resistance with reduced weight
  • Safety system: Integrated MIPS to help reduce rotational forces in certain impacts
  • Coverage: Extended facial protection and increased rear head coverage compared to open-face helmets
  • Finish: Matte exterior surface
  • Fit system: Internal fit adjustment (Float Fit) and sweat management features
  • Comfort: Ventilation ports for airflow and an adjustable visor

How to use

Choose the correct helmet size for a snug, secure fit around the head. Adjust the internal fit system so the helmet sits level on the head and the rim does not obstruct vision. Use the chin strap and buckle to fasten the helmet, ensuring the strap is snug but comfortable and the chin pad rests comfortably under the jaw. Adjust the visor and ventilation as needed for visibility and airflow during rides. After any significant impact, replace the helmet or have it inspected according to manufacturer guidance.

What to consider before purchase

  • Intended use: confirm that full-face coverage and MIPS protection match your riding style (aggressive trail, enduro)
  • Size and fit: measure head circumference and consult sizing to select the correct size range
  • Certification and regional availability: check local dealer information for certification and color/price availability

Usage recommendations

Regularly inspect the helmet for visible damage, clean with mild soap and water, and replace it after significant impacts or according to the manufacturer’s lifespan guidelines. Use this helmet for off-road and trail riding where extended protection is desired, and pair it with other appropriate protective gear such as gloves and pads.
