AGV K1 S Street Full-Face Motorcycle Helmet Matte Black, Medium — DOT, Pinlock-ready visor

Built to balance protection, airflow and an expansive field of view, the K1 S Street blends a high-resistance thermoplastic shell with race-proven details and user-friendly features. Its two-shell sizing improves fit across head shapes while a Pinlock-ready wide visor keeps vision clear. Removable, washable interior pads and straightforward controls make it practical for daily commuters and occasional sport riders alike.

How does the AGV K1 S Street protect while staying lightweight?

The helmet uses a durable thermoplastic outer shell engineered for impact resistance without excess weight. Offering two shell sizes helps maintain a compact profile across medium and larger sizes, keeping bulk minimal.

• High-resistance thermoplastic shell built for street impacts
• Two shell sizes for a balanced, proportionate fit
• Double-D ring chinstrap proven in racing environments for reliable retention
• Meets DOT FMVSS 218 safety standard for road use

Will ventilation and visibility meet everyday riding needs?

Yes—the K1 S Street incorporates large intake vents at the front and crown, paired with rear extractors to pull heat and moisture away from the head. A wide GT4-compatible visor (Pinlock MaxVision-prepared) gives a broad field of view and reduces peripheral obstruction.

• Front and crown vents maximize fresh air entry
• Rear extractors help constant airflow and heat evacuation
• GT4 visor cut for an expanded visual range; clear visor included
• Pinlock MaxVision preparation supports anti-fog inserts for damp conditions

How comfortable and practical is the liner and fit for frequent use?

The interior uses removable, washable padding to keep the helmet feeling fresh after long commutes or multi-day trips. The double-D chinstrap offers an adjustable, secure closure that racers and street riders trust, while the shell sizing strategy reduces pressure points for better long-ride comfort.

• Removable, washable inner liner for hygiene and longevity
• Double-D ring chinstrap for a compact, secure fit
• Two shell sizes to better match head shape and reduce hotspots
• Medium size tailored for average adult head circumference

What accessories and maintenance should I consider?

The helmet ships with a clear GT4 visor and is prepared for Pinlock MaxVision anti-fog inserts, so adding a Pinlock insert can improve fog resistance. Routine cleaning of the removable liner and periodic inspection of vents and the chinstrap will keep performance consistent.

• Clear visor included; Pinlock MaxVision insert compatible
• Clean removable liners with mild soap and air-dry only
• Check vents and extractors for debris after off-road or dirty commutes
• Replace visor or inner padding if worn or damaged
