Leatt Helmet MTB Enduro 4.0 V26

The Leatt MTB Enduro 4.0 V26 Helmet is a premium enduro helmet built for riders who want serious downhill-level protection without being locked into a permanently fixed full-face helmet. Its removable chin bar gives you the flexibility to ride with full-face protection when the trail gets technical, then remove it for longer climbs or less demanding sections.

The Enduro 4.0 uses a lightweight polycarbonate shell combined with dual-density EPS and EPO impact foam to provide protection across a range of impact speeds. Leatt's 360° Turbine Technology works alongside the impact foam as part of a three-stage protection system, helping manage rotational forces as well as energy from lower- and higher-speed impacts. The helmet is ASTM F1952 downhill certified and also carries NTA 8776 certification for suitable high-speed e-bike applications.

Despite its full-face capability, ventilation is a major part of the Enduro 4.0's design. 18 vents are positioned to maintain airflow even at lower speeds, which is particularly important during long South African climbs and warmer riding conditions. The removable mouthpiece can also be used to increase airflow or provide additional coverage in poor weather.

A Fidlock magnetic buckle makes securing the helmet quick and straightforward, while the adjustable breakaway visor provides additional functionality on the trail. A dedicated sunglasses dock gives you a convenient place to store your eyewear when you switch to climbing or stop for a break.

The easy-fit removable chin bar system is what makes this helmet particularly versatile. Rather than carrying a second helmet for different parts of your ride, you can adapt the Enduro 4.0 to suit the terrain you're riding.

Who is this best suited for?
The Leatt Enduro 4.0 V26 is best suited to enduro riders, aggressive trail riders, e-MTB riders and mountain bikers who want the protection of a DH-certified full-face helmet with the flexibility of a removable chin bar.

It's particularly well suited to riders who face long climbs followed by technical descents and don't want to choose between ventilation and protection. For South African MTB riding, where temperatures can rise quickly and trails can vary significantly during the same ride, the ability to adapt the helmet is a major advantage.
