MT Helmets Thunder 4 SV – Sport-Touring Excellence
The Thunder 4 SV stands at the top of MT Helmets' sport-touring range, offering exceptional performance, comfort, and value. Engineered for long-distance riding, it delivers outstanding ergonomics, enhanced safety features, and a broad field of vision — all while maintaining an eco-conscious design for long-term durability.
Crafted for sport-touring riders, the Thunder 4 SV is built with HIRP (High Impact Resistance Polymer), striking the perfect balance between weight and safety. Its interior features removable, washable, and hypoallergenic liners, ensuring a fresh and hygienic ride on every journey.
Developed using fluid dynamics, the helmet’s airflow channel system delivers maximum ventilation with minimal drag. The wide-view face shield comes equipped with a Pinlock 100% MaxVision anti-fog lens for clear vision in all weather conditions, while the improved retractable sun visor offers full coverage and UV protection.
MT-QVSS (Quick Visor Swap System): Easily change visors in seconds — even with the helmet on.
Emergency Release System: Allows safe and fast removal in the event of an accident.
Shield Lock: Prevents accidental visor opening during impact.
Reflective Fabric: Increases visibility during night rides.
The Thunder 4 SV is Bluetooth-compatible and features a dedicated intercom compartment designed for UCS (Universal Communications System) intercoms — the new industry standard. Designed with sustainability in mind, its modular components can be easily replaced to extend the helmet’s lifespan and reduce environmental impact.
