MT Thunder 4 SV Full Face Helmet

Advanced European Safety. Aerodynamic Performance. Touring Comfort.

The MT Thunder 4 SV Full Face Helmet is engineered for riders who demand world-class safety, aerodynamic efficiency, and long-distance comfort. Designed with advanced European technology, the Thunder 4 SV combines cutting-edge impact protection with intelligent ventilation and rider-focused ergonomics, making it an ideal choice for touring, sport riding, and everyday commuting.

Constructed using HIRP (High Impact Resistant Polymer), a specially formulated polymer blend, the shell delivers exceptional impact resistance while maintaining an optimized weight for enhanced rider comfort. Every aspect of the helmet has been developed to provide superior protection without compromising everyday usability.

The aerodynamic shell incorporates MT-RADD (Reduced Aero Drag Design), a technology developed through extensive engineering and airflow analysis to minimize wind resistance, improve high-speed stability, and reduce rider fatigue on extended journeys.

Complementing its aerodynamic profile is the MT-AFCS (Air Flow Channel System), an advanced internal ventilation network designed using computational fluid dynamics. Strategically positioned air channels maximize airflow circulation while efficiently removing heat and moisture, ensuring a cooler and more comfortable riding experience across varying weather conditions.

Adding to its practicality, the helmet features MT's exclusive Three-Point Protector System, which provides enhanced stability when the helmet is placed on flat surfaces. This innovative design minimizes contact between the interior liner and external surfaces, helping reduce wear while improving cleanliness and overall hygiene.

The redesigned MT-MDTC (Micrometric Double Toothed Closure) retention system delivers a secure and reliable fit by locking at multiple engagement points, offering an excellent balance of rider comfort, convenience, and safety for everyday riding and long-distance touring.

Certified to the latest ECE 22.06, DOT, and ISI safety standards, the MT Thunder 4 SV meets and exceeds some of the world's most demanding helmet certification requirements, providing riders with complete confidence on every journey.

Measure your head ~2 cm above the eyebrows and match it to our size chart. It should sit snug with no pressure points and barely move once fastened. Always buckle the chin strap fully before riding, and replace the helmet after any major impact.

Channelled ventilation keeps you cool, a Pinlock-ready visor stays fog-free, and a lightweight shell with plush padding keeps you comfortable — commute, tour or weekend ride.
