Stilo ST5.1 GT Carbon: the Legend Continues

The ST5.1 GT Carbon is Stilo's Snell SA2020-compliant version of their legendary best-selling carbon helmet. With an autoclave molded carbon fiber shell, the Stilo Helmets ST5.1 GT Carbon offers strength superior to fiberglass and composites while minimizing weight.

With its large eye-port, the Stilo ST5.1 GT Carbon offers unsurpassed peripheral vision and all of the available tinted, mirrored, and iridium-colored visors (sold separately) have a center pinch-clip to make opening and closing easy, even while wearing nomex racing gloves.

Although updated to meet the newest Snell SA2020 certification, the Stilo ST5.1 GT Carbon also retains its FIA 8858-2015 homologation. This makes the helmet legal for nearly all road race usage (except for those sanctioning bodies requiring FIA 8860 homologation).

Stilo Helmets Famously Flexible Integration

The Stilo Helmets ST5.1 GT Carbon is unsurpassed in built-in flexibility. Its two side ports can be fitted separately with integrated communication electronics, forced air, helmet eject system, or a driver hydration system. Thanks to its innovative shell design, mounting and routing these options into the ST5.1 GT is sleek and seamless.

Whether you're using side-mounted communications, side air, or a built-in hydration kit for staying hydrated during long enduro stints, everything is neat, tidy and completely out of the way when not needed. Stilo simply offers the best-designed modular racing helmet on the market.

Industry-standard M6 threaded receivers are molded into the helmet shell to accommodate anchors for your head-and-neck restraint.

Stilo Sizing Note:

We have found that customers who typically wear a size 59 in other brands are most comfortable in a Stilo size 60, which uses the large shell. Please order accordingly.

Measuring Your Head

The most effective helmet is one that fits properly. To measure your head, have an assistant use a dressmaker's tape or a piece of string to measure the circumference of your head. Start at a point about an inch above your eyebrows, looping around the back of your head at the point that results in the largest measurement, and finally around to the front again. It's a good idea to take two or three measurements to make sure you have the largest one.
