AGV K1 S Street full-face motorcycle helmet — Black, Large | DOT-certified, Pinlock-ready ventilation

AGV K1 S Street is a DOT-certified full-face motorcycle helmet engineered for everyday riders who want a lightweight shell, strong ventilation, and a wide, Pinlock-ready visor.

The K1 S Street from AGV blends track-derived design with street-focused practicality. Built on a high-resistance thermoplastic shell available in two shell sizes, this large black helmet balances protection and comfort while keeping weight down. It includes adjustable airflow, a wide GT4-style visor prepared for Pinlock MaxVision inserts, and a removable, washable interior to simplify upkeep. The double-D ring chinstrap and DOT (FMVSS 218) certification ensure it meets U.S. safety requirements for legal road use.

How does the AGV K1 S Street keep riders cool on long rides?

Ventilation is prioritized to maintain a fresh airflow through the helmet during extended use. Large intake vents at the front and crown work with rear extractors to move warm air out and bring cooler air in, reducing heat build-up without adding complexity.

• Large front and crown vents for significant air intake
• Rear extractors expel warm air for continuous circulation
• Internal channels route airflow across the head for even cooling

What vision features make this helmet practical for street riding?

The K1 S Street provides a broad field of view thanks to its GT4-inspired visor geometry, improving situational awareness in traffic. The visor comes clear and is Pinlock MaxVision-prepared, so you can add an anti-fog insert for wet or cold conditions without altering the helmet shell.

• Wide GT4 visor opening for improved peripheral sight
• Pinlock MaxVision-prepared visor compatibility to reduce fogging
• Clear visor included so you can ride immediately out of the box

Is the fit secure and easy to maintain for everyday use?

Fit and fasten are straightforward with race-proven hardware and a design that balances stability and comfort. The helmet uses a double-D ring chinstrap for a positive closure, and the interior pads are removable and washable to keep the helmet fresh after daily use.

• Double-D ring chinstrap for a secure, proven closure system
• Two shell sizes for an optimized, balanced fit across head shapes
• Removable, washable liner for simple maintenance and hygiene
