The Thunder 4 SV features a sharp, aerodynamic shell profile that gives it a sporty appearance without sacrificing everyday comfort. Aggressive lines, a streamlined rear spoiler and contemporary styling help the helmet look at home on sportsbikes, naked motorcycles and sport-tourers alike.
Its aerodynamic design also helps improve stability at higher speeds, making it a strong choice for riders who regularly combine commuting with motorway travel.

ECE 22.06 Certified Protection
One of the standout features of the Thunder 4 SV is its compliance with the latest ECE 22.06 safety standard. This certification requires more demanding impact and rotational testing than previous regulations, helping ensure the helmet meets modern protection requirements.
The helmet's shell and multi-density EPS liner are engineered to provide effective energy absorption while maintaining rider comfort and manageable overall weight.
Integrated Sun Visor Convenience
Touring riders and commuters will appreciate the integrated drop-down sun visor. Easily operated while wearing gloves, the internal sun visor allows riders to adapt quickly to changing light conditions without needing to swap visors or carry additional eye protection.
This feature proves particularly useful during early morning rides, bright summer days and journeys that extend into the evening.

Comfortable Interior for Everyday Riding
The Thunder 4 SV uses a removable and washable interior lining designed to maintain comfort during both short commutes and longer touring journeys. Soft-touch materials and carefully shaped padding help create a secure fit while reducing pressure points during extended riding sessions.
The moisture-managing interior also contributes to rider comfort in warmer conditions and during regular daily use.

Advanced Ventilation System
Maintaining airflow is essential for rider comfort, and the Thunder 4 SV incorporates multiple intake and exhaust vents designed to channel fresh air throughout the helmet. Effective airflow helps reduce heat build-up and improves comfort during warmer weather and slower-moving traffic.
The ventilation system works in conjunction with the internal channels of the EPS liner to maximise airflow efficiency.
Wide Vision and Pinlock Compatibility
The helmet's wide visor aperture provides excellent visibility and enhanced peripheral awareness. Whether navigating busy urban traffic or enjoying fast-flowing country roads, the broad field of vision helps improve rider confidence and situational awareness.
Pinlock compatibility also helps minimise visor fogging, allowing riders to maintain clearer vision during cold mornings and wet-weather riding.
Prepared for Modern Riding Technology
Many riders now use communication systems for navigation, music and rider-to-rider communication. The Thunder 4 SV offers a design that accommodates modern Bluetooth communication systems, making it easy to integrate technology into everyday rides and longer tours.
This flexibility enhances the helmet's appeal for both solo riders and touring groups.
