Pre-Order

With Pre-Order, you can purchase the latest items added to our store in advance of them arriving with us.

Your Pre-Order is prioritised (at no additional charge); meaning that as soon as the product arrives with us, we can wrap it straight back up; ready for collection via Click & Collect or despatch to you — it often never even hits the stock room shelves!

Pre-Launch

With Pre-Launch, the date when we expect to receive the product ourselves is still a little too hazy to be confident in accepting Pre-Orders.

Leatt Enduro 4.0 MTB Full Face Helmet in Stealth Black/Grey

Season:All Year Round

Brand:Leatt

Code:LE102301445Stea

Renowned for its ventilation and comfort, this enduro MTB helmet has been advanced from the much loved 4.0 full face helmet. Packed with unique features, there is not another helmet on the market like it! 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.

A universal sunglasses dock lets you safely dock your sunglasses under the visor when not in use, protected from scratches and unwanted impacts. The adjustable visor opens up enough to place your goggles underneath, so you do not have to constantly remove them. This fully ASTM DH certified helmet is the go-to helmet for enduro riders. Uphill or downhill, e-bike or trail - you name it, the Leatt 4.0 Enduro helmet has you covered. The full-face design with removable chin bar with an incredible strong magnesium lock offers outstanding ventilation and its convenient Fidlock buckle makes life just peachy!

Safety Technology:

  • 360 Turbine Technology: Reduces both rotation acceleration and concussion level impact energy to your head and brain.
  • Rotation Protection: The optimally designed turbine discs enable the helmet to move slightly on the head upon impact, helping to reduce peak acceleration to the head and brain.
  • Low Impact Protection: The special energy absorbing material in the turbines absorbs low impact energy associated with concussion.
  • Impact Foam: In-molded, dual-density EPS + EP0 impact foam for superior energy absorption.
  • Visor Breakaway Function: Adjustable visor with breakaway function for rotational impact force reduction.

Design and Comfort Features:

  • Removable Chin Bar: A removable mouthpiece in the chin bar increases ventilation or can be installed to protect you when riding in poor weather conditions.
  • Ventilation: 18 vents effective even at low speeds.
  • Liner: Moisture wicking, breathable, anti-odor and washable inner liner.
  • Fit System: Flat Lock Strap divider and fit system developed for custom fit, ease, and comfort.
  • Closure: Fidlock magnetic closure system.
  • Other Features: Optimal neck brace compatibility; soft touch and moisture wicking chin straps.

Technical Specifications:

  • Shell: DH certified lightweight polycarbonate shell
  • Safety System: 3-in-1 safety system (when combined with the impact foam, 360° Turbine Technology offers protection against low-speed impacts, high-speed impacts, and rotational forces)
  • Weight: From 810g (1.79 lbs)
  • Certifications: AS/NZS 2063:2008, ASTM F1952–10, EN1078, CPSC 1203, NTA 8776 (Helmets for S-EPAC riders)
