AGV K1 S Street Full-Face Motorcycle Helmet Black Large — DOT, Pinlock-Ready

The AGV K1 S Street is a DOT-approved full-face motorcycle helmet that pairs a lightweight, high-resistance thermoplastic shell with active ventilation and a wide-view Pinlock-prepared visor for reliable everyday protection and comfort.

Built to balance affordability, comfort, and performance, the AGV K1 S Street was designed for street riders who want a dependable full-face helmet without extra bulk. It uses two shell sizes to improve fit across head shapes, a washable interior for easy care, and a clear GT4 visor ready for Pinlock MaxVision to reduce fogging in variable conditions.

How does the helmet manage airflow on longer rides?

Ventilation is engineered to move fresh air in and expel warm air quickly. Large front and crown intakes feed cooling air into channels, while rear extractors push heat and moisture out to help regulate temperature.

• Prominent chin and crown vents for increased intake
• Rear extractors for continuous exhaust flow
• Internal air channels that reduce helmet interior heat buildup
• Vent controls accessible with gloved hands

What visibility and visor features does the K1 S Street offer?

The helmet includes a wide-field GT4 visor that comes clear out of the box and is prepared for a Pinlock MaxVision insert to cut down on fogging. The visor design maximizes peripheral vision and is user-friendly for quick changes when needed.

• Pinlock MaxVision-prepared GT4 visor for anti-fog capability
• Wide opening for improved peripheral sightlines
• Tool-free visor removal and replacement
• Clear visor included; tinted options available separately

Is the fit secure and comfortable for daily use?

Yes — the K1 S Street uses a race-proven double-D ring chinstrap to ensure a snug closure, and removable, washable interior pads for long-term hygiene. Two shell sizes allow a closer match to different head circumferences for a more balanced feel.

• Double-D ring chinstrap for a reliable, adjustable closure
• Removable and washable liner to maintain freshness
• Two-shell sizing strategy to improve overall fit and stability
• Padded cheek pieces for comfort on extended rides

Does the helmet meet safety standards and what materials are used?

The AGV K1 S Street meets DOT FMVSS 218 certification for use on U.S. roads and features a high-resistance thermoplastic outer shell built to manage impact energy. The construction focuses on balanced protection while remaining lightweight for everyday riding.

• Certified to DOT FMVSS 218 for road use in the U.S.
• High-resistance thermoplastic shell in two sizes for fit optimization
• Internal EPS energy-absorbing liner to dissipate impact forces
• Washable interior materials that maintain shape and comfort

Who is this for? The AGV K1 S Street (Black, Large) is ideal for commuter and casual sport riders who want a full-face helmet that combines proven safety standards, good ventilation, and easy-care interiors without the premium price of composite shells. It suits riders who prioritize clear sightlines and anti-fog readiness, need a secure double-D chinstrap, and prefer a helmet that’s simple to maintain.
