The Enduro 4.0 helmet is built as a full-face-first option for enduro racers who want downhill-certified protection with the flexibility to remove the chin bar for long climbs or mellower trails. The lightweight polycarbonate shell is paired with in-molded dual-density EPS + EPO impact foam to meet ASTM F1952–10 (downhill MTB) and NTA 8776 (e-bike) standards—delivering serious coverage for high-speed descents and e-MTB rides. Leatt’s 360° Turbine Technology helps reduce rotational forces and absorb low-speed impact energy, working together with the impact foam as a 3-in-1 safety system. For enduro racing and aggressive days in the saddle, the Enduro 4.0 delivers DH-level protection in a versatile, race-ready design.
