(Sun Visor) is a mid-range, full-face motorcycle helmet designed for versatility across commuting, touring, and sport riding. It incorporates racing-derived aerodynamics and a high-resistance thermoplastic shell, while featuring a convenient drop-down internal sun visor.
Core Technical Features
The helmet is engineered using Finite Element Analysis (FEM) to balance safety, weight, and comfort.
Shell Construction: Made from HIR-TH (High Resistance Thermoplastic Resin), the shell is contoured at the base specifically to reduce the risk of collarbone injuries during an impact.
Integrated Sun Visor (ISV): A scratch-resistant internal visor that can be operated easily with gloves and replaced without tools.
Ventilation System: Features a high-flow system optimized in wind tunnels, consisting of four front vents (three on the forehead, one on the chin) and two rear extractors.
Visor Mechanism: Uses the Extra Quick Release System (XQRS) for tool-free shield swaps and the Personalized Visor Mechanism (PVM) to customize the opening steps (Touring, Race, or City).
Interior: The 3D inner liner is made from Dry-Comfort fabric, which is fully removable, washable, and sanitized.
Performance and Safety Ratings
Safety Certifications: Most models available in 2026 are certified to ECE 22.06 standards, which include rigorous rotational impact testing. Older variants often carry ECE 22.05 and DOT ratings.
Aerodynamics: According to the official AGV technical sheet, the shell is designed to have zero dynamic weight at speeds of 130 km/h (80 mph), significantly reducing neck fatigue.
SHARP Rating: The AGV K3 SV has previously earned a 4/5 star rating from the SHARP safety testing program.
