The Simpson Speed is the newest addition to Simpson's ECE-certified motorcycle helmet lineup and it makes an immediate impression. Built for riders who refuse to compromise on either safety or style, this matt black lid carries the unmistakable Simpson attitude in a package that's lighter than you'd expect. Whether you're carving through morning commutes or weekend canyon runs, the Speed delivers the confidence to push harder. Engineered with a lightweight thermo-injected polycarbonate shell available in three shell sizes, the Speed ensures an optimum outer profile across all six sizing options (XS to XXL). The signature Simpson Speed Brow channels airflow through a low-pressure venturi effect, working in tandem with venturi chin vents and a central rear exhaust vent to keep you cool under pressure. The ultra-wide, quick-release shield offers a maximum field of view with a 4-position locking feature and it's Pinlock ready for fog-free riding in all conditions. Comfort is where the Speed truly earns its keep. The padded hypoallergenic liner wraps your head in a soft, skin-friendly fit that's fully removable and washable for long-term freshness. The adjustable 4-position shield locks precisely where you need it, and with Pinlock compatibility, fogging up on cold or wet rides is a thing of the past. Speaker cut-outs are built in for seamless communication system integration, and the Double D-ring retention system keeps everything secure mile after mile. This is a helmet built for riders who mean business.
