LEATT Gravity 4.0 MTB Helmet — Lightweight DH protection for enduro and bike park

The LEATT Gravity 4.0 MTB Helmet in stealth black/grey is for riders who refuse to compromise between certified downhill safety and everyday comfort. Designed for enduro, bike park sessions, and e-MTB rides, it combines lightness, breathability, and advanced protection on every meter of the trail.

Construction and materials

The polymer composite shell houses a molded, dual-density EPS and EPO impact foam, designed to absorb impact energy at both low and high speeds. This combination of materials ensures a robust yet lightweight structure, ideal for technical terrain where every impact counts.

360° Turbine Technology

At the heart of the Gravity 4.0 is Leatt 's exclusive Turbine 360° technology, which forms a unique 3-in-1 safety system:

• Protection against rotational forces : carefully optimized "turbine" discs allow slight relative movement between the helmet and the head during an impact, helping to reduce the maximum acceleration transmitted to the brain.
• Low-speed protection : EPO foam absorbs low-energy impacts to preserve comfort during minor contacts.
• High-speed protection : EPS foam absorbs the high-energy impacts characteristic of rapid downhill falls.

This system is combined with a detachable visor which, in the event of a fall, helps to reduce rotational impact forces.

Ventilation

With its 22 strategically placed vents, the Gravity 4.0 maintains efficient airflow even at low speeds. The removable chin vent cover allows you to adjust airflow according to riding conditions, offering valuable flexibility for both climbs and descents.

Comfort and fit

The Dri-Lex® inner lining ensures rapid moisture wicking while remaining breathable and odor-resistant. Fully washable, it maintains a fresh and clean environment, even on long rides. The closure is secured by a Fidlock magnetic buckle, allowing for effortless, one-handed helmet entry and removal, even with gloves. The Gravity 4.0 is also compatible with Leatt neck braces for riders seeking an additional level of protection.

The Gravity 4.0 helmet is certified according to the most demanding standards on the market:

• AS/NZS 2063:2008
• ASTM F1952–10
