Advanced Shell Construction

The helmet features a shell constructed from HIRP High Impact Resistance Polymer. This material offers an excellent balance between impact protection and reduced weight. The Thunder 4 R SV is available in two outer shell sizes for improved fit across the size range.

Ventilation and Aerodynamics

The refined Airflow Channel System improves internal airflow efficiency. A dual button front intake allows precise ventilation control, while rear extraction ports assist with hot air removal. The redesigned spoiler and diffuser enhance aerodynamic stability at speed.

Visor and Vision Performance

The Thunder 4 R SV uses the MT V 28C visor with MT Quick Visor Swap System, allowing shield changes in seconds. The visor includes a lock system to prevent unintentional opening during impact. When the visor lock button is pressed, it opens to a first anti fog position to improve airflow and reduce misting. The helmet is Pinlock DKS435 ready and prepared for a MaxVision 70 insert. A retractable internal sun visor fully covers the viewing area for improved glare protection.

Comfort and Safety Features

The interior is made from hypoallergenic fabrics and is fully removable and washable. An emergency release system allows safe cheek pad removal in the event of an accident. The helmet includes a micrometric closure system with double teeth retention for secure fastening. A nose deflector and housing for an intercom system headset are also included.

The 3 point protector system helps prevent surface rubbing and improves hygiene by protecting key helmet areas. The Thunder 4 R SV is also designed with replaceable elements to extend product life.
